<strong>Fluke Calibration PPCH<\/strong> is specifically designed for automated hydraulic high-pressure calibration.<\/p>\n<p>Its operating range extends from approximately:<\/p>\n<p><strong>1 MPa<\/strong><\/p>\n<p>to:<\/p>\n<p><strong>200 MPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>150 psi to 30,000 psi<\/strong><\/p>\n<p>The maximum pressure corresponds to approximately:<\/p>\n<p><strong>2,000 bar<\/strong><\/p>\n<p>This pressure capability makes the PPCH suitable for demanding high-pressure applications that exceed the ranges of many conventional pneumatic pressure controllers.<\/p>\n<p>Typical devices under test include:<\/p>\n<ul data-spread=\"false\">\n<li>High-pressure sensors<\/li>\n<li>Pressure transducers<\/li>\n<li>Pressure transmitters<\/li>\n<li>Digital pressure gauges<\/li>\n<li>Mechanical pressure gauges<\/li>\n<li>Reference pressure transducers<\/li>\n<li>Industrial high-pressure instrumentation<\/li>\n<\/ul>\n<h2>Four Maximum Pressure Configurations<\/h2>\n<p>The <strong>Fluke Calibration PPCH<\/strong> can be configured according to the maximum required pressure.<\/p>\n<p>Available controller configurations include:<\/p>\n<p><strong>PPCH-70M<\/strong><\/p>\n<p>Maximum controlled pressure:<\/p>\n<p><strong>70 MPa \/ 10,000 psi \/ approximately 700 bar<\/strong><\/p>\n<p><strong>PPCH-100M<\/strong><\/p>\n<p>Maximum controlled pressure:<\/p>\n<p><strong>100 MPa \/ 15,000 psi \/ approximately 1,000

to be selected according to the actual high-pressure workload.<\/p>\n<h2>Automatic Hydraulic Pressure Generation<\/h2>\n<p>Traditional high-pressure hydraulic calibration often requires considerable manual effort.<\/p>\n<p>Manual pumps and pressure intensifiers must be operated repeatedly, while fine adjustment devices are required to reach the desired pressure accurately.<\/p>\n<p>The <strong>Fluke Calibration PPCH<\/strong> automates this process.<\/p>\n<p>The system generates the required hydraulic pressure and automatically approaches the selected setpoint.<\/p>\n<p>This provides major advantages when many calibration points or repetitive pressure sequences are required.<\/p>\n<h2>Q-RPT Quartz Reference Pressure Transducers<\/h2>\n<p>The outstanding pressure measurement performance of the PPCH is based on Fluke Calibration <strong>Q-RPT technology<\/strong>.<\/p>\n<p>Q-RPT stands for:<\/p>\n<p><strong>Quartz Reference Pressure Transducer<\/strong><\/p>\n<p>The sensor determines pressure by measuring the change in the natural oscillation frequency of a quartz crystal caused by pressure-induced mechanical stress.<\/p>\n<p>Individual transducers are characterized before they are selected for use as reference pressure transducers.<\/p>\n<p>The resulting 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 measurement performance<\/li>\n<\/ul>\n<p>Q-RPT technology makes the PPCH suitable for demanding calibration and transfer-standard applications.<\/p>\n<h2>Available Q-RPT Pressure Ranges<\/h2>\n<p>Several Q-RPT ranges are available for the <strong>Fluke Calibration PPCH<\/strong>.<\/p>\n<p>These include:<\/p>\n<ul data-spread=\"false\">\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<li><strong>A140M \u2013 140 MPa \/ 20,000 psi<\/strong><\/li>\n<li><strong>A200M \u2013 200 MPa \/ 30,000 psi<\/strong><\/li>\n<\/ul>\n<p>The A100M, A140M and A200M modules are available only in the high Q-RPT position.<\/p>\n<p>The low Q-RPT position uses a range of A70M or lower.<\/p>\n<p>This enables a PPCH system to combine pressure ranges for improved measurement performance over the required workload.<\/p>\n<h2>Excellent Measurement Performance<\/h2>\n<p>For Q-RPT ranges below A200M, Fluke specifies precision of:<\/p>\n<p><strong>\u00b10.012 % of reading<\/strong><\/p>\n<p>For the A200M Q-RPT, precision is:<\/p>\n<p><strong>\u00b10.015 % of reading<\/strong><\/p>\n<p>Predicted one-year stability is:<\/p>\n<p><strong>\u00b10.005 % of reading<\/strong><\/p>\n<p>for both configurations when the AutoZero function is used as specified.<\/p>\n<p>Delivered measurement uncertainty for Q-RPTs below A200M is:<\/p>\n<p><strong>\u00b10.013 % of reading<\/strong><\/p>\n<p>For the A200M Q-RPT, delivered measurement uncertainty is:<\/p>\n<p><strong>\u00b10.018 % of reading<\/strong><\/p>\n<p>The percent-of-reading specifications apply from 30 % to 100 % of the selected Q-RPT span. Below 30 %, the corresponding 30 % span value is used.<\/p>\n<h2>Dynamic Pressure Uncertainty<\/h2>\n<p>When the PPCH is actively controlling pressure in dynamic mode, the complete pressure uncertainty includes both measurement uncertainty and the dynamic control contribution.<\/p>\n<p>Fluke specifies pressure uncertainty in dynamic control mode of:<\/p>\n<p><strong>\u00b10.016 % of reading<\/strong><\/p>\n<p>for Q-RPTs below A200M.<\/p>\n<p>For the A200M range, the corresponding specification is:<\/p>\n<p><strong>\u00b10.020 % of reading<\/strong><\/p>\n<p>These values apply under the manufacturer&#8217;s specified conditions and over the defined portion of the Q-RPT range.<\/p>\n<h2>High-Resolution Pressure Control<\/h2>\n<p>The <strong>Fluke Calibration PPCH<\/strong> provides pressure control precision to:<\/p>\n<p><strong>\u00b10.003 % of Q-RPT span<\/strong><\/p>\n<p>The controller offers a pressure control turndown of:<\/p>\n<p><strong>10:1<\/strong><\/p>\n<p>This allows the hydraulic pressure generation system to be adapted to different calibration ranges.<\/p>\n<p>Measurement resolution is user-adjustable down to:<\/p>\n<p><strong>1 ppm<\/strong><\/p>\n<p>This combination of measurement resolution and automatic pressure control makes the PPCH suitable for high-performance hydraulic pressure calibration.<\/p>\n<h2>AutoRange Function<\/h2>\n<p>One of the important features of the <strong>Fluke Calibration PPCH<\/strong> is AutoRange.<\/p>\n<p>The AutoRange function automatically adapts the controller to the pressure range of the device under test.<\/p>\n<p>Instead of operating every test using the complete maximum range of the controller, AutoRange optimizes relevant parameters for the selected DUT range.<\/p>\n<p>This includes aspects of:<\/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>Test parameters<\/li>\n<\/ul>\n<p>This simplifies operation when the same PPCH is used to calibrate devices with very different pressure ranges.<\/p>\n<h2>Infinite Ranging<\/h2>\n<p>Fluke Calibration refers to the broad adaptability of the PPCH as <strong>Infinite Ranging<\/strong>.<\/p>\n<p>True rangeability involves more than simply specifying measurement uncertainty as a percentage of reading.<\/p>\n<p>The pressure controller must also adapt its control characteristics and operating parameters to the device under test.<\/p>\n<p>The PPCH combines Q-RPT measurement technology with AutoRange to optimize operation for the selected calibration range.<\/p>\n<p>This enables one controller to cover a wide variety of high-pressure devices.<\/p>\n<h2>Open Measurement Architecture<\/h2>\n<p>The <strong>Fluke Calibration PPCH<\/strong> provides a flexible open architecture.<\/p>\n<p>Reference pressure measurement can be:<\/p>\n<ul data-spread=\"false\">\n<li>Integrated into the PPCH<\/li>\n<li>Located externally<\/li>\n<li>Positioned closer to the device under test<\/li>\n<\/ul>\n<p>A PPCH can be configured with one or two internal Q-RPT modules.<\/p>\n<p>Alternatively, external Q-RPTs can be installed in an <strong>RPM4 Reference Pressure Monitor<\/strong>.<\/p>\n<p>The PPCH then manages the external Q-RPT as part of the pressure control system.<\/p>\n<p>This architecture can be particularly useful when the reference sensor needs to be removed separately for recalibration while the controller remains installed.<\/p>\n<h2>PPCH without Internal Q-RPT<\/h2>\n<p>The PPCH can also be configured without an internal Q-RPT.<\/p>\n<p>In this configuration, a lower-cost utility sensor provides basic pressure indication and control capability.<\/p>\n<p>An external RPM4 containing the required Q-RPT can then provide the reference pressure measurement.<\/p>\n<p>Another possible application is using the PPCH primarily as an automatic hydraulic pressure generation and control system.<\/p>\n<p>This provides considerable flexibility when designing specialized high-pressure calibration systems.<\/p>\n<h2>Dynamic Control Mode<\/h2>\n<p>In <strong>Dynamic Mode<\/strong>, the PPCH automatically reaches the target pressure and continuously adjusts pressure to maintain the selected setpoint.<\/p>\n<p>This mode is useful when pressure must remain actively controlled during measurement.<\/p>\n<p>Small changes caused by factors such as temperature or system behavior are automatically compensated by the controller.<\/p>\n<h2>Static Control Mode<\/h2>\n<p>In <strong>Static Mode<\/strong>, the PPCH generates the target pressure within the defined hold limit and then stops active control.<\/p>\n<p>The hydraulic system is allowed to stabilize naturally.<\/p>\n<p>This mode can be advantageous for high-accuracy measurements where continuous control activity is undesirable.<\/p>\n<h2>Monotonic Control Mode<\/h2>\n<p>The <strong>Monotonic Mode<\/strong> is designed for applications where pressure should approach the target while maintaining a very slow pressure change in the same direction as the original pressure increment.<\/p>\n<p>This specialized mode provides additional flexibility for demanding pressure calibration procedures.<\/p>\n<h2>Ramp Control Mode<\/h2>\n<p>The PPCH also provides a programmable <strong>Ramp Mode<\/strong>.<\/p>\n<p>The user defines the required rate of pressure change.<\/p>\n<p>The controller then generates and maintains the specified pressure ramp.<\/p>\n<p>This can be useful for:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure sensor characterization<\/li>\n<li>Pressure switch testing<\/li>\n<li>Dynamic pressure testing<\/li>\n<li>Component testing<\/li>\n<li>Research applications<\/li>\n<\/ul>\n<h2>Piston Gauge Control<\/h2>\n<p>The <strong>Fluke Calibration PPCH<\/strong> can also be integrated into automated piston gauge systems.<\/p>\n<p>In Piston Gauge Mode, a compatible piston gauge system can control the PPCH.<\/p>\n<p>For example, the PPCH can provide automated hydraulic pressure generation for a PG7000-series piston gauge system.<\/p>\n<p>This eliminates much of the manual pressure generation normally required when operating a high-pressure piston gauge.<\/p>\n<h2>Automatic Fluid Head Correction<\/h2>\n<p>Hydraulic pressure measurements are affected by differences in vertical height.<\/p>\n<p>Because the pressure medium has a much higher density than gas, fluid head correction can be particularly significant in hydraulic pressure calibration.<\/p>\n<p>The <strong>Fluke Calibration PPCH<\/strong> therefore provides automatic fluid pressure head correction.<\/p>\n<p>This enables the pressure indication to be corrected for the vertical distance between the reference level and the device under test.<\/p>\n<p>Correct reference-level definition is essential for high-accuracy hydraulic pressure calibration.<\/p>\n<h2>Intelligent AutoZero<\/h2>\n<p>The PPCH includes an intelligent <strong>AutoZero<\/strong> function.<\/p>\n<p>Regular zeroing helps maintain the measurement performance of the Q-RPT reference sensors.<\/p>\n<p>In gauge pressure mode, AutoZero can occur automatically when the system is vented.<\/p>\n<p>For absolute pressure operation, a suitable barometric reference can be used for the AutoZero process.<\/p>\n<p>This function contributes to the excellent long-term stability specifications of the Q-RPT system.<\/p>\n<h2>Automated Calibration Sequences<\/h2>\n<p>The <strong>Fluke Calibration PPCH<\/strong> can store and execute programmable calibration sequences.<\/p>\n<p>This allows frequently used pressure calibration procedures to be automated directly from the controller.<\/p>\n<p>The system can also perform DUT tolerance testing.<\/p>\n<p>This can reduce operator workload during repetitive calibration tasks.<\/p>\n<p>A remote ENTER footswitch can be used for hands-free execution of test steps.<\/p>\n<h2>Automated Leak Testing<\/h2>\n<p>High-pressure hydraulic systems must be sufficiently leak-tight to achieve stable pressure.<\/p>\n<p>The PPCH therefore includes automated leak testing routines.<\/p>\n<p>These functions help evaluate the pressure system before or during calibration.<\/p>\n<p>Leak testing can help identify problems with:<\/p>\n<ul data-spread=\"false\">\n<li>Pressure fittings<\/li>\n<li>Tubing<\/li>\n<li>Adapters<\/li>\n<li>Devices under test<\/li>\n<li>Seals<\/li>\n<li>Test connections<\/li>\n<\/ul>\n<p>This can improve both calibration efficiency and measurement reliability.<\/p>\n<h2>Pressure Medium<\/h2>\n<p>The standard operating medium for the <strong>Fluke Calibration PPCH<\/strong> is:<\/p>\n<p><strong>Sebacate oil<\/strong><\/p>\n<p>Other operating fluids may be available for special applications in consultation with Fluke Calibration.<\/p>\n<p>The internal reservoir volume is:<\/p>\n<p><strong>250 cc<\/strong><\/p>\n<p>An external reservoir can also be used.<\/p>\n<p>Correct fluid selection is important for both measurement performance and compatibility with the device under test.<\/p>\n<h2>Calibration of High-Pressure Sensors<\/h2>\n<p>The PPCH is particularly suitable for calibration and characterization of high-pressure sensors.<\/p>\n<p>The controller automatically generates the required pressure while the Q-RPT provides the reference measurement.<\/p>\n<p>An external data acquisition system can simultaneously record the electrical output of the sensor.<\/p>\n<p>Typical 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>Automatic 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 <strong>Fluke Calibration PPCH<\/strong>.<\/p>\n<p>The PPCH generates and measures the hydraulic reference pressure.<\/p>\n<p>Suitable electrical measurement equipment measures the transmitter output.<\/p>\n<p>Typical transmitter outputs include:<\/p>\n<ul data-spread=\"false\">\n<li>4\u201320 mA<\/li>\n<li>DC voltage<\/li>\n<li>Digital signals<\/li>\n<\/ul>\n<p>Automated pressure control significantly reduces manual effort when multiple calibration points must be tested.<\/p>\n<h2>Calibration of Pressure Gauges<\/h2>\n<p>The PPCH can be used for automatic calibration of high-pressure mechanical and digital pressure gauges.<\/p>\n<p>A typical calibration sequence includes increasing and decreasing pressure points.<\/p>\n<p>The gauge indication is compared with the reference pressure measured by the Q-RPT.<\/p>\n<p>Depending on the calibration procedure, the results can be used to evaluate:<\/p>\n<ul data-spread=\"false\">\n<li>Indication

<strong>Fluke Calibration PPCH<\/strong> is designed for laboratories and production environments that require automated hydraulic pressure generation at pressures beyond the practical operating range of many pneumatic controllers.<\/p>\n<p>With a maximum pressure of <strong>200 MPa (30,000 psi \/ approximately 2,000 bar)<\/strong>, the PPCH covers demanding high-pressure calibration and testing applications.<\/p>\n<p>Automatic hydraulic pressure generation eliminates much of the manual work traditionally associated with high-pressure liquid systems.<\/p>\n<p>The system&#8217;s Q-RPT quartz reference pressure transducers provide excellent measurement performance, with delivered measurement uncertainty down to <strong>\u00b10.013 % of reading<\/strong> for suitable configurations.<\/p>\n<p>AutoRange automatically adapts important measurement and control parameters to the range of the device under test.<\/p>\n<p>The open measurement architecture allows Q-RPT reference sensors to be installed internally or remotely in an RPM4 Reference Pressure Monitor.<\/p>\n<p>Four different pressure control modes provide flexibility for calibration, sensor characterization and specialized testing applications.<\/p>\n<p>Integration with compatible piston gauges further expands the PPCH into primary and high-level reference pressure systems.<\/p>\n<p>Automatic fluid head correction, intelligent AutoZero, programmable calibration sequences and automated leak testing simplify demanding high-pressure calibration
