bar<\/h2>\n<p>The outstanding feature of the <strong>Additel ADT 761A-1.5K<\/strong> is its ability to automatically generate pneumatic pressure up to:<\/p>\n<p><strong>100 bar(g)<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>1,500 psig<\/strong><\/p>\n<p>without requiring an external high-pressure gas cylinder for normal pressure generation.<\/p>\n<p>The internal high-performance electric pump generates the required pneumatic pressure and the integrated controller automatically regulates the pressure to the selected setpoint.<\/p>\n<p>This provides a major advantage over conventional calibration setups consisting of separate:<\/p>\n<ul>\n<li>Pressure pumps<\/li>\n<li>Pressure controllers<\/li>\n<li>Reference pressure gauges<\/li>\n<li>Fine adjustment valves<\/li>\n<li>Electrical process calibrators<\/li>\n<li>Communication devices<\/li>\n<\/ul>\n<p>The ADT 761A-1.5K integrates these functions into a portable automated calibration platform.<\/p>\n<h2>Pressure Range from Vacuum to 1,500 psi<\/h2>\n<p>The ADT 761A-1.5K generates and controls pressure from vacuum conditions up to:<\/p>\n<p><strong>1,500 psig<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>100 bar(g)<\/strong><\/p>\n<p>The high-range CP1.5K module covers approximately:<\/p>\n<p><strong>-13.5 to 1,500 psig<\/strong><\/p>\n<p>This corresponds approximately to:<\/p>\n<p><strong>-0.9 to 100 bar(g)<\/strong><\/p>\n<p>The combination of vacuum and positive pressure generation provides a wide operating span for calibrating many different pneumatic pressure instruments.<\/p>\n<h2>Gauge and Absolute Pressure<\/h2>\n<p>The <strong>Additel ADT 761A-1.5K<\/strong> supports both:<\/p>\n<p><strong>Gauge Pressure<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Absolute Pressure<\/strong><\/p>\n<p>Gauge pressure is referenced to atmospheric pressure:<\/p>\n<p><strong>p_gauge = p_absolute &#8211; p_atmosphere<\/strong><\/p>\n<p>Absolute pressure is referenced to an ideal vacuum:<\/p>\n<p><strong>p_absolute = p_gauge + p_atmosphere<\/strong><\/p>\n<p>The integrated barometric reference enables the ADT 761A-1.5K to use its gauge pressure modules for absolute pressure applications.<\/p>\n<p>This significantly increases the versatility of the calibrator.<\/p>\n<h2>Integrated Barometric Reference<\/h2>\n<p>An integrated barometer measures the surrounding atmospheric pressure.<\/p>\n<p>This allows the instrument to convert between gauge and absolute pressure values without requiring a separate external barometer.<\/p>\n<p>The barometric reference is particularly useful when a calibration laboratory needs to handle both gauge and absolute pressure instruments using the same portable calibration platform.<\/p>\n<h2>Dual Internal Pressure Modules<\/h2>\n<p>One of the key features of the <strong>Additel ADT 761A-1.5K<\/strong> is its ability to accommodate:<\/p>\n<p><strong>two internal pressure modules<\/strong><\/p>\n<p>The high-pressure position is equipped with the:<\/p>\n<p><strong>CP1.5K<\/strong><\/p>\n<p>module.<\/p>\n<p>This module covers the high-pressure range up to 1,500 psi \/ 100 bar.<\/p>\n<p>A second internal pressure module can be configured for a lower pressure range.<\/p>\n<p>For the ADT 761A-1.5K, lower-range configurations are available down to approximately:<\/p>\n<p><strong>35 psi \/ 2.5 bar(g)<\/strong><\/p>\n<p>This dual-module concept is particularly useful when the same calibrator must be used for instruments with widely differing measuring ranges.<\/p>\n<h2>Why Two Pressure Modules Are Useful<\/h2>\n<p>Pressure sensor accuracy is commonly specified relative to the sensor&#8217;s full span.<\/p>\n<p>Using only a 100 bar sensor to calibrate a device at a few bar can therefore result in a relatively large absolute accuracy contribution.<\/p>\n<p>The ADT 761A-1.5K solves this problem by allowing a second lower-range module to be installed.<\/p>\n<p>For example, the high-range module can be used for high-pressure instruments while the lower-range module is selected automatically or manually for lower-pressure devices.<\/p>\n<p>This extends the useful measurement capability of the system.<\/p>\n<h2>Accuracy Down to 0.01 % FS<\/h2>\n<p>Depending on the selected pressure module, the <strong>Additel ADT 761A-1.5K<\/strong> can provide pressure accuracy down to:<\/p>\n<p><strong>0.01 % FS<\/strong><\/p>\n<p>Other module configurations are available with:<\/p>\n<p><strong>0.02 % FS<\/strong><\/p>\n<p>accuracy.<\/p>\n<p>FS refers to the full span of the respective pressure module.<\/p>\n<p>For professional calibration applications, selecting an appropriate internal module range is therefore important for achieving the required measurement uncertainty.<\/p>\n<h2>Automatic Pressure Control<\/h2>\n<p>Generating pressure is only one part of a professional automatic calibration system.<\/p>\n<p>The ADT 761A-1.5K also automatically controls the generated pressure.<\/p>\n<p>The user enters the desired setpoint and the instrument:<\/p>\n<ol start=\"1\">\n<li>Generates the required pressure<\/li>\n<li>Approaches the selected setpoint<\/li>\n<li>Regulates the pressure<\/li>\n<li>Stabilizes the pressure<\/li>\n<li>Measures the reference pressure<\/li>\n<\/ol>\n<p>This makes repetitive multipoint calibrations significantly more efficient than manual pressure generation.<\/p>\n<h2>Automated Calibration Tasks<\/h2>\n<p>The <strong>Additel ADT 761A-1.5K<\/strong> supports automated calibration procedures.<\/p>\n<p>Calibration tasks can be configured for repetitive workflows involving several increasing and decreasing pressure points.<\/p>\n<p>This is particularly useful when calibrating instruments such as:<\/p>\n<ul>\n<li>Digital pressure gauges<\/li>\n<li>Analog pressure gauges<\/li>\n<li>Pressure transmitters<\/li>\n<li>Pressure sensors<\/li>\n<li>Pressure transducers<\/li>\n<li>Pressure switches<\/li>\n<\/ul>\n<p>Automated procedures improve consistency and reduce repetitive manual operation.<\/p>\n<h2>Electrical Process Calibration<\/h2>\n<p>In addition to pressure generation and measurement, the ADT 761A platform provides electrical process calibration functionality.<\/p>\n<p>This allows the pressure input and electrical output of a transmitter to be evaluated with one calibration system.<\/p>\n<p>A typical example is a:<\/p>\n<p><strong>4\u201320 mA pressure transmitter<\/strong><\/p>\n<p>The ADT 761A-1.5K generates the required reference pressure while simultaneously measuring the transmitter&#8217;s electrical output.<\/p>\n<p>This reduces the need for separate instruments in many field calibration applications.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>The instrument provides:<\/p>\n<p><strong>24 V loop power<\/strong><\/p>\n<p>for compatible process transmitters.<\/p>\n<p>This is particularly useful for two-wire 4\u201320 mA pressure transmitters.<\/p>\n<p>The calibrator can therefore provide:<\/p>\n<ul>\n<li>Reference pressure<\/li>\n<li>Transmitter loop power<\/li>\n<li>Electrical signal measurement<\/li>\n<\/ul>\n<p>within one integrated calibration setup.<\/p>\n<h2>HART Communication<\/h2>\n<p>The <strong>Additel ADT 761A-1.5K<\/strong> supports:<\/p>\n<p><strong>HART communication<\/strong><\/p>\n<p>for compatible smart pressure transmitters.<\/p>\n<p>HART capability allows communication with intelligent field instruments for tasks such as:<\/p>\n<ul>\n<li>Device identification<\/li>\n<li>Configuration<\/li>\n<li>Reading digital process values<\/li>\n<li>Diagnostics<\/li>\n<li>Calibration support<\/li>\n<\/ul>\n<p>This makes the ADT 761A-1.5K particularly useful for modern process instrumentation.<\/p>\n<h2>PROFIBUS PA Support<\/h2>\n<p>The ADT761A platform also provides support for:<\/p>\n<p><strong>PROFIBUS PA<\/strong><\/p>\n<p>communication.<\/p>\n<p>This expands the application range beyond conventional analog transmitters and allows the calibration system to be used with compatible digital process instrumentation.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>The <strong>Additel ADT 761A-1.5K<\/strong> can also be used for pressure switch calibration.<\/p>\n<p>Automatic pressure generation allows the pressure to be increased and decreased in a controlled manner.<\/p>\n<p>This makes it possible to determine:<\/p>\n<ul>\n<li>Switching point<\/li>\n<li>Reset point<\/li>\n<li>Hysteresis<\/li>\n<\/ul>\n<p>with significantly less manual adjustment than a conventional hand-pump setup.<\/p>\n<h2>Data Logging<\/h2>\n<p>The ADT761A provides integrated data logging capability.<\/p>\n<p>Additel specifies internal storage for up to:<\/p>\n<p><strong>1,000,000 time- and date-stamped readings<\/strong><\/p>\n<p>This allows measurement data to be recorded directly by the calibrator.<\/p>\n<p>Data logging is particularly useful for:<\/p>\n<ul>\n<li>Long-term pressure monitoring<\/li>\n<li>Stability testing<\/li>\n<li>Calibration documentation<\/li>\n<li>Process measurements<\/li>\n<li>Troubleshooting<\/li>\n<\/ul>\n<h2>External Pressure Modules<\/h2>\n<p>The ADT761A platform also supports external pressure modules.<\/p>\n<p>This allows additional pressure ranges to be measured beyond the two installed internal modules.<\/p>\n<p>External modules can therefore extend the usefulness of the ADT 761A-1.5K as a general pressure measurement and calibration platform.<\/p>\n<p>The external module does not replace the pressure-generation limits of the internal pneumatic system; it expands pressure measurement capability.<\/p>\n<h2>Modern Communication Interfaces<\/h2>\n<p>The <strong>Additel ADT 761A-1.5K<\/strong> provides several communication interfaces, including:<\/p>\n<ul>\n<li>Wi-Fi<\/li>\n<li>Bluetooth<\/li>\n<li>USB<\/li>\n<li>Ethernet<\/li>\n<\/ul>\n<p>These interfaces allow the calibrator to be integrated into modern calibration and data-management workflows.<\/p>\n<p>Wireless communication is particularly useful for field applications, while Ethernet and USB provide convenient wired connectivity in laboratory environments.<\/p>\n<h2>Touchscreen Operation<\/h2>\n<p>The ADT761A uses a large touchscreen user interface.<\/p>\n<p>Pressure setpoints, measurement functions, calibration tasks and instrument settings can be accessed directly from the display.<\/p>\n<p>The graphical interface simplifies the configuration of automated calibration procedures and reduces the number of external controls required.<\/p>\n<h2>Portable High-Pressure Calibration<\/h2>\n<p>Generating pneumatic pressure up to 100 bar normally requires comparatively substantial pressure-generation equipment.<\/p>\n<p>The ADT 761A-1.5K combines high pneumatic pressure capability with a portable architecture.<\/p>\n<p>This makes it particularly attractive for applications where pressure instruments cannot easily be removed from the process and transported to a stationary laboratory pressure controller.<\/p>\n<p>The calibrator can instead be brought to the device under test.<\/p>\n<h2>Technical
