Combining automatic gas pressure generation and control with Q-RPT quartz reference pressure transducer technology, AutoRange and flexible system architecture, the PPCH-G provides a powerful solution for professional calibration laboratories, pressure sensor manufacturers, research facilities and automated production testing.<\/p>\n<p>Unlike the hydraulic Fluke Calibration PPCH, the <strong>PPCH-G uses gas as its pressure medium<\/strong>. This makes the system particularly attractive for high-pressure devices that must remain free from hydraulic oil or other liquid contamination.<\/p>\n<p>The PPCH-G platform is available in controller configurations with maximum pressures of <strong>20 MPa, 40 MPa, 70 MPa and 100 MPa<\/strong>, corresponding to approximately <strong>200, 400, 700 and 1,000 bar<\/strong> or <strong>3,000, 6,000, 10,000 and 15,000 psi<\/strong>.<\/p>\n<p>High-accuracy reference pressure measurement is provided by Fluke Calibration <strong>Q-RPT \u2013 Quartz Reference Pressure Transducer<\/strong> technology. Available Q-RPT ranges extend from <strong>7 MPa (1,000 psi)<\/strong> to <strong>100 MPa (15,000 psi)<\/strong>.<\/p>\n<p>Depending on the configuration, the PPCH-G can contain one or two internal Q-RPT modules. Additional external Q-RPTs installed in RPM4 Reference Pressure Monitors can also be integrated into the system. Up to four Q-RPT modules can be included in a complete PPCH-G configuration.<\/p>\n<p>This open architecture enables the pressure reference to be selected according to the calibration workload and

PPCH-G<\/strong> was specifically developed for automated high-pressure gas calibration.<\/p>\n<p>Depending on the selected controller configuration, pressures can be generated and controlled up to:<\/p>\n<p><strong>100 MPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>15,000 psi<\/strong><\/p>\n<p>which corresponds to approximately:<\/p>\n<p><strong>1,000 bar<\/strong><\/p>\n<p>This high pneumatic pressure capability enables many sensors and pressure instruments to be calibrated without using a hydraulic pressure medium.<\/p>\n<p>The PPCH-G is therefore particularly valuable when cleanliness and gas compatibility are important.<\/p>\n<h2>PPCH-G Controller Configurations<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> was offered in several maximum-pressure configurations.<\/p>\n<p>These include:<\/p>\n<p><strong>PPCH-G-20M<\/strong><\/p>\n<p>Maximum controller pressure:<\/p>\n<p><strong>20 MPa \/ 3,000 psi \/ approximately 200 bar<\/strong><\/p>\n<p><strong>PPCH-G-40M<\/strong><\/p>\n<p>Maximum controller pressure:<\/p>\n<p><strong>40 MPa \/ 6,000 psi \/ approximately 400 bar<\/strong><\/p>\n<p><strong>PPCH-G-70M<\/strong><\/p>\n<p>Maximum controller pressure:<\/p>\n<p><strong>70 MPa \/ 10,000 psi \/ approximately 700 bar<\/strong><\/p>\n<p><strong>PPCH-G-100M<\/strong><\/p>\n<p>Maximum controller pressure:<\/p>\n<p><strong>100 MPa \/ 15,000 psi \/ approximately 1,000 bar<\/strong><\/p>\n<p>The appropriate configuration can therefore be selected according to the required high-pressure workload.<\/p>\n<h2>Q-RPT Quartz Reference Pressure Transducers<\/h2>\n<p>The measurement performance of the <strong>Fluke Calibration PPCH-G<\/strong> is based on Fluke Calibration Q-RPT technology.<\/p>\n<p>Q-RPT stands for:<\/p>\n<p><strong>Quartz Reference Pressure Transducer<\/strong><\/p>\n<p>The sensor determines pressure from pressure-induced changes in the natural oscillation frequency of quartz elements.<\/p>\n<p>Individual pressure transducers are characterized before selection for use as Q-RPT reference modules.<\/p>\n<p>The resulting reference system provides excellent:<\/p>\n<ul data-spread=\"false\">\n<li>Linearity<\/li>\n<li>Repeatability<\/li>\n<li>Stability<\/li>\n<li>Resolution<\/li>\n<li>Long-term performance<\/li>\n<\/ul>\n<p>Q-RPT technology is designed specifically for demanding reference and transfer-standard applications.<\/p>\n<h2>Available Q-RPT Ranges<\/h2>\n<p>The following Q-RPT maximum ranges are available for the <strong>Fluke Calibration PPCH-G<\/strong>:<\/p>\n<ul data-spread=\"false\">\n<li><strong>A7M \u2013 7 MPa \/ 1,000 psi<\/strong><\/li>\n<li><strong>A10M \u2013 10 MPa \/ 1,500 psi<\/strong><\/li>\n<li><strong>A20M \u2013 20 MPa \/ 3,000 psi<\/strong><\/li>\n<li><strong>A40M \u2013 40 MPa \/ 6,000 psi<\/strong><\/li>\n<li><strong>A70M \u2013 70 MPa \/ 10,000 psi<\/strong><\/li>\n<li><strong>A100M \u2013 100 MPa \/ 15,000 psi<\/strong><\/li>\n<\/ul>\n<p>Different Q-RPT ranges can be combined to optimize measurement performance over the required calibration workload.<\/p>\n<h2>Standard and Premium Q-RPT Performance<\/h2>\n<p>For the lower Q-RPT ranges, Fluke Calibration offered different performance classes.<\/p>\n<p>For suitable <strong>Premium Class<\/strong> lower-range Q-RPT configurations, precision can reach:<\/p>\n<p><strong>\u00b10.005 % of reading<\/strong><\/p>\n<p>subject to the specified AutoRange and Q-RPT span limits.<\/p>\n<p>Measurement uncertainty for these Premium configurations can reach:<\/p>\n<p><strong>\u00b10.008 % of reading<\/strong><\/p>\n<p>under the applicable conditions.<\/p>\n<p>For Standard Class lower-range Q-RPTs, precision and measurement uncertainty are specified at correspondingly higher values.<\/p>\n<p>This allows the system to be configured according to the required measurement uncertainty and calibration workload.<\/p>\n<h2>High-Pressure Q-RPT Performance<\/h2>\n<p>For higher-pressure Q-RPTs, Fluke specifies precision as the greater of:<\/p>\n<p><strong>\u00b10.012 % of reading<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.0036 % of Q-RPT span<\/strong><\/p>\n<p>Measurement uncertainty is specified as the greater of:<\/p>\n<p><strong>\u00b10.013 % of reading<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.004 % of Q-RPT span<\/strong><\/p>\n<p>The percent-of-reading specification applies over the manufacturer&#8217;s specified portion of the Q-RPT range.<\/p>\n<p>This provides excellent measurement capability for high-pressure pneumatic calibration.<\/p>\n<h2>Long-Term Stability<\/h2>\n<p>Fluke specifies predicted one-year Q-RPT measurement stability of:<\/p>\n<p><strong>\u00b10.005 % of reading<\/strong><\/p>\n<p>when the AutoZero function is used as specified.<\/p>\n<p>Long-term stability is particularly important when the PPCH-G is used as a reference instrument in a professional calibration laboratory.<\/p>\n<p>Stable reference performance helps maintain predictable measurement uncertainty between calibration intervals.<\/p>\n<h2>Resolution Down to 1 ppm<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> provides user-adjustable measurement resolution down to:<\/p>\n<p><strong>1 ppm<\/strong><\/p>\n<p>High resolution makes small pressure changes visible and helps operators evaluate pressure stability.<\/p>\n<p>Resolution should not be confused with measurement uncertainty, but it is an important practical characteristic in high-accuracy pressure calibration.<\/p>\n<h2>AutoRange Function<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> includes Fluke Calibration&#8217;s AutoRange function.<\/p>\n<p>AutoRange adapts the controller to the pressure range of the device under test.<\/p>\n<p>Instead of operating every calibration according to the complete maximum range of the system, AutoRange optimizes relevant operating parameters for the selected DUT range.<\/p>\n<p>This helps optimize:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure measurement<\/li>\n<li>Pressure control<\/li>\n<li>Resolution<\/li>\n<li>Ready criteria<\/li>\n<li>Safety limits<\/li>\n<li>Calibration parameters<\/li>\n<\/ul>\n<p>AutoRange therefore simplifies operation when devices with significantly different pressure ranges are calibrated using the same system.<\/p>\n<h2>Infinite Ranging<\/h2>\n<p>Fluke Calibration describes the broad adaptability of the PPCH-G as <strong>Infinite Ranging<\/strong>.<\/p>\n<p>Wide rangeability requires more than a percent-of-reading measurement specification.<\/p>\n<p>Pressure control behavior and other operating parameters must also adapt to the actual calibration range.<\/p>\n<p>By combining Q-RPT reference technology with AutoRange, the PPCH-G can adapt to a broad range of pressure devices and calibration requirements.<\/p>\n<h2>Open Measurement Architecture<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> provides a flexible open architecture.<\/p>\n<p>A complete system can incorporate up to:<\/p>\n<p><strong>four Q-RPT modules<\/strong><\/p>\n<p>These reference modules can be located internally or externally.<\/p>\n<p>External Q-RPT modules are installed in:<\/p>\n<p><strong>RPM4 Reference Pressure Monitors<\/strong><\/p>\n<p>The PPCH-G then manages these external Q-RPTs as part of the complete pressure control system.<\/p>\n<p>This architecture provides considerable flexibility when designing a high-pressure calibration workstation.<\/p>\n<h2>One or Two Internal Q-RPTs<\/h2>\n<p>A standalone <strong>Fluke Calibration PPCH-G<\/strong> can be configured with one or two internal Q-RPT modules.<\/p>\n<p>This creates a compact pressure controller\/calibrator with integrated reference pressure measurement.<\/p>\n<p>Two ranges can be selected to provide improved measurement performance across a broader calibration workload.<\/p>\n<p>For many applications, this provides a complete automated high-pressure calibration solution in a single system.<\/p>\n<h2>External Q-RPT Reference<\/h2>\n<p>An external RPM4 can be used when it is advantageous to position the reference pressure measurement separately from the pressure controller.<\/p>\n<p>For example, the reference sensor can be positioned closer to the device under test.<\/p>\n<p>This can reduce the influence of pressure gradients or other installation effects.<\/p>\n<p>Another advantage is that the external reference can be removed for recalibration while the PPCH-G remains installed in the calibration system.<\/p>\n<p>External Q-RPTs must be disconnected or suitably protected when the PPCH-G is operated above their maximum pressure range.<\/p>\n<h2>Operation without an Internal Q-RPT<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> was also available without an internal high-accuracy Q-RPT.<\/p>\n<p>In this configuration, a lower-cost utility sensor provides pressure indication and supports safety and control functions.<\/p>\n<p>An external RPM4 with Q-RPT can then provide the high-accuracy reference measurement.<\/p>\n<p>Alternatively, the PPCH-G can be used primarily as an automatic high-pressure gas generation and control system.<\/p>\n<p>This architecture provides flexibility when an existing external reference standard is already available.<\/p>\n<h2>Dynamic Pressure Control<\/h2>\n<p>In dynamic pressure control mode, the <strong>Fluke Calibration PPCH-G<\/strong> automatically approaches the target pressure and actively maintains the selected setpoint.<\/p>\n<p>Small pressure changes caused by system behavior or temperature effects are continuously compensated.<\/p>\n<p>Fluke specifies a typical time to ready in dynamic mode of approximately:<\/p>\n<p><strong>90 to 150 seconds<\/strong><\/p>\n<p>depending on the system configuration and operating conditions.<\/p>\n<h2>Lowest Controllable Pressure<\/h2>\n<p>The specified lowest controllable pressure for the PPCH-G is approximately:<\/p>\n<p><strong>0.7 MPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>100 psi<\/strong><\/p>\n<p>This characteristic reflects the controller&#8217;s specialization in high-pressure pneumatic calibration.<\/p>\n<p>For significantly lower pressure ranges, other Fluke Calibration controller platforms are more appropriate.<\/p>\n<h2>Gas Operation and Clean Calibration<\/h2>\n<p>One of the major advantages of the <strong>Fluke Calibration PPCH-G<\/strong> is the use of gas rather than hydraulic liquid.<\/p>\n<p>High-pressure calibration has traditionally relied heavily on hydraulic pressure generation.<\/p>\n<p>Hydraulic systems are highly effective but can introduce oil into the device under test.<\/p>\n<p>Gas operation avoids this issue.<\/p>\n<p>This is particularly useful for:<\/p>\n<ul data-spread=\"false\">\n<li>Gas pressure sensors<\/li>\n<li>Clean pressure systems<\/li>\n<li>Aerospace instrumentation<\/li>\n<li>Sensor production<\/li>\n<li>Research equipment<\/li>\n<li>Devices that must remain free from hydraulic oil<\/li>\n<\/ul>\n<h2>Calibration of Pressure Sensors<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> is particularly suitable for automatic calibration and characterization of high-pressure sensors.<\/p>\n<p>The controller automatically generates the required gas pressure while the Q-RPT provides the reference measurement.<\/p>\n<p>External electrical measurement equipment can simultaneously record the sensor output.<\/p>\n<p>Typical sensor characteristics that can be evaluated include:<\/p>\n<ul data-spread=\"false\">\n<li>Zero<\/li>\n<li>Span<\/li>\n<li>Linearity<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Pressure sensitivity<\/li>\n<\/ul>\n<p>Automated pressure generation is especially useful when many measurement points or repeated pressure cycles are required.<\/p>\n<h2>Calibration of Pressure Transmitters<\/h2>\n<p>High-pressure transmitters can also be calibrated using the PPCH-G.<\/p>\n<p>The controller generates and measures the required pneumatic reference pressure.<\/p>\n<p>Suitable electrical measurement equipment measures the transmitter output.<\/p>\n<p>Typical signals include:<\/p>\n<ul data-spread=\"false\">\n<li>4\u201320 mA<\/li>\n<li>DC voltage<\/li>\n<li>Digital output signals<\/li>\n<\/ul>\n<p>Automatic pressure generation reduces manual work and improves repeatability during multipoint transmitter calibration.<\/p>\n<h2>Calibration of Pressure Gauges<\/h2>\n<p>Mechanical and digital high-pressure gauges can also be calibrated using the <strong>Fluke Calibration PPCH-G<\/strong>.<\/p>\n<p>The controller automatically generates defined pressure points.<\/p>\n<p>The indication of the device under test is compared with the pressure measured by the Q-RPT reference.<\/p>\n<p>Increasing and decreasing pressure sequences allow characteristics such as:<\/p>\n<ul data-spread=\"false\">\n<li>Indication deviation<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Zero deviation<\/li>\n<\/ul>\n<p>to be evaluated.<\/p>\n<h2>Piston Gauge Automation<\/h2>\n<p>The PPCH-G can also be used to automate pressure generation for a compatible piston gauge.<\/p>\n<p>Fluke specifically describes configurations in which a PPCH-G with an integrated Q-RPT provides automated pressure control for a:<\/p>\n<p><strong>PG7202 piston gauge<\/strong><\/p>\n<p>This significantly reduces the manual pressure generation traditionally associated with high-pressure piston gauge operation.<\/p>\n<p>It also enables advanced high-pressure reference systems combining automatic pressure generation with piston gauge metrology.<\/p>\n<h2>Intelligent AutoZero<\/h2>\n<p>The Q-RPT system supports automatic zeroing.<\/p>\n<p>In gauge mode, AutoZero can be performed when the pressure system is vented.<\/p>\n<p>For absolute pressure operation, suitable reference techniques can be used.<\/p>\n<p>Regular AutoZero operation contributes to the specified long-term stability of the Q-RPT measurement system.<\/p>\n<h2>High-Pressure Connections<\/h2>\n<p>High-pressure gas calibration requires suitable pressure-rated connections and tubing.<\/p>\n<p>The PPCH-G uses dedicated high-pressure fittings for its test gas supply and test connections.<\/p>\n<p>All components connected to the system must be rated for the maximum intended operating pressure.<\/p>\n<p>This includes:<\/p>\n<ul data-spread=\"false\">\n<li>Tubing<\/li>\n<li>Adapters<\/li>\n<li>Valves<\/li>\n<li>Pressure fittings<\/li>\n<li>Devices under test<\/li>\n<\/ul>\n<p>Correct installation is particularly important because compressed gas stores significantly more energy than hydraulic liquid at comparable pressures.<\/p>\n<h2>Safety at High Gas Pressure<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> can operate at gas pressures approaching 100 MPa.<\/p>\n<p>This represents a significant amount of stored energy.<\/p>\n<p>Appropriate high-pressure safety procedures are therefore essential.<\/p>\n<p>The calibration installation should include suitable:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure-rated tubing<\/li>\n<li>High-pressure fittings<\/li>\n<li>Mechanical protection<\/li>\n<li>Safe venting arrangements<\/li>\n<li>Operating procedures<\/li>\n<li>Personnel training<\/li>\n<\/ul>\n<p>The maximum pressure ratings of all components must always be observed.<\/p>\n<h2>Automated Calibration<\/h2>\n<p>The PPCH-G is designed for integration into automated calibration systems.<\/p>\n<p>Remote communication allows software to control functions such as:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure setpoints<\/li>\n<li>Pressure generation<\/li>\n<li>Pressure stabilization<\/li>\n<li>Measurement acquisition<\/li>\n<li>Calibration sequences<\/li>\n<li>Leak testing<\/li>\n<li>Device-under-test evaluation<\/li>\n<\/ul>\n<p>Automation is particularly useful in production and calibration environments with repetitive high-pressure workloads.<\/p>\n<h2>Technical Highlights<\/h2>\n<p>The

PPCH-G?<\/h2>\n<p>The <strong>Fluke Calibration PPCH-G<\/strong> combines automatic high-pressure gas generation with precision reference pressure measurement.<\/p>\n<p>With maximum controller configurations up to <strong>100 MPa (15,000 psi \/ approximately 1,000 bar)<\/strong>, the system enables demanding high-pressure calibration without requiring hydraulic oil as the pressure medium.<\/p>\n<p>This is particularly valuable for pressure sensors, transducers and other devices that must remain clean and free from liquid contamination.<\/p>\n<p>Q-RPT quartz reference pressure transducers provide excellent measurement stability, repeatability and resolution.<\/p>\n<p>Available Q-RPT ranges from <strong>7 MPa to 100 MPa<\/strong> allow the reference system to be matched to the required calibration workload.<\/p>\n<p>The AutoRange function automatically adapts important measurement and control parameters to the range of the device under test.<\/p>\n<p>Open architecture allows internal and external Q-RPTs to be combined, with up to four Q-RPT modules available in a complete system.<\/p>\n<p>An external RPM4 reference can be positioned closer to the device under test or removed separately for recalibration.<\/p>\n<p>The PPCH-G can also automate pressure generation for compatible piston gauges such as the PG7202.<\/p>\n<p>These capabilities make the PPCH-G suitable for demanding calibration laboratories, pressure sensor production and automated high-pressure test systems.<\/p>\n<p>The <strong>PPCH-G has been discontinued or reclassified by Fluke Calibration<\/strong>. Fluke currently recommends the <strong>8270A and 8370A Modular High-Pressure Controllers\/Calibrators<\/strong> as successor solutions.
