Pressure Generation from -0.86 to 2.5 bar<\/h2>\n<p>The <strong>Additel ADT 760A-D<\/strong> is designed specifically for gauge and differential pressure calibration.<\/p>\n<p>Its maximum pressure generation and control range is:<\/p>\n<p><strong>-0.86 to +2.5 bar<\/strong><\/p>\n<p>corresponding to:<\/p>\n<p><strong>-12.5 to +35 psi<\/strong><\/p>\n<p>The negative pressure capability allows the calibrator to generate vacuum relative to atmospheric pressure, while positive pressure can be automatically generated up to 2.5 bar.<\/p>\n<p>This bidirectional pressure capability makes the ADT 760A-D particularly useful for process instrumentation and differential pressure applications.<\/p>\n<h2>Fully Automatic Pressure Generation<\/h2>\n<p>One of the major advantages of the <strong>Additel ADT 760A-D<\/strong> is its integrated automatic pressure generation.<\/p>\n<p>A conventional field calibration setup may require:<\/p>\n<ul>\n<li>Manual pressure pump<\/li>\n<li>Reference pressure gauge<\/li>\n<li>Pressure adjustment valve<\/li>\n<li>Electrical process calibrator<\/li>\n<li>Test leads<\/li>\n<li>Pressure tubing<\/li>\n<\/ul>\n<p>The ADT 760A-D combines many of these functions into one compact instrument.<\/p>\n<p>The user enters the desired pressure setpoint and the internal electric pump and pressure controller automatically generate and regulate the required pressure.<\/p>\n<p>This significantly reduces manual pumping and fine adjustment during repetitive calibration procedures.<\/p>\n<h2>Pressure Accuracy up to 0.01 % FS<\/h2>\n<p>Depending on the installed interchangeable ADT155 internal pressure module, the ADT 760A-D provides pressure accuracy of:<\/p>\n<p><strong>0.01 % FS<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.02 % FS<\/strong><\/p>\n<p>FS refers to the span of the selected pressure module.<\/p>\n<p>This modular approach allows the internal pressure measurement range to be selected according to the actual application.<\/p>\n<p>Using a lower-range pressure module can improve the absolute measurement performance when calibrating instruments significantly below the maximum 2.5 bar pressure capability.<\/p>\n<h2>Pressure Control Stability<\/h2>\n<p>The specified pressure stability is:<\/p>\n<p><strong>0.005 % FS<\/strong><\/p>\n<p>The stability specification is based on the full scale of the installed internal pressure module.<\/p>\n<p>Stable pressure control is particularly important during automated calibration because the device under test should be evaluated only after the reference pressure has reached a sufficiently stable condition.<\/p>\n<h2>Gauge and Differential Pressure<\/h2>\n<p>The <strong>Additel ADT 760A-D<\/strong> supports:<\/p>\n<p><strong>Gauge pressure<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Differential pressure<\/strong><\/p>\n<p>This distinguishes the D version from the MA version of the ADT760A family.<\/p>\n<p>Differential pressure capability is especially useful for calibration of instruments such as:<\/p>\n<ul>\n<li>Differential pressure transmitters<\/li>\n<li>Low-pressure transmitters<\/li>\n<li>Filter monitoring instruments<\/li>\n<li>Flow transmitters using differential pressure<\/li>\n<li>Pressure switches<\/li>\n<li>Process pressure instruments<\/li>\n<\/ul>\n<h2>Interchangeable ADT155 Pressure Modules<\/h2>\n<p>The ADT 760A-D uses interchangeable internal pressure modules from the <strong>Additel ADT155 series<\/strong>.<\/p>\n<p>This provides an important advantage over instruments with only one permanently installed measuring range.<\/p>\n<p>The internal module can be selected according to the pressure range and required accuracy.<\/p>\n<p>The maximum module compatible with the ADT 760A-D supports pressure up to:<\/p>\n<p><strong>35 psi \/ 2.5 bar<\/strong><\/p>\n<p>Lower pressure configurations are also available.<\/p>\n<p>For improved performance at lower differential pressures, configurations down to approximately:<\/p>\n<p><strong>\u00b110 inH\u2082O<\/strong><\/p>\n<p>can be selected.<\/p>\n<p>This allows the same ADT 760A-D platform to be adapted to different calibration tasks.<\/p>\n<h2>Pressure Measurement Resolution<\/h2>\n<p>The pressure display provides:<\/p>\n<p><strong>6-digit resolution<\/strong><\/p>\n<p>A wide selection of pressure units is supported, including:<\/p>\n<ul>\n<li>Pa<\/li>\n<li>hPa<\/li>\n<li>kPa<\/li>\n<li>MPa<\/li>\n<li>bar<\/li>\n<li>mbar<\/li>\n<li>psi<\/li>\n<li>mmHg<\/li>\n<li>cmHg<\/li>\n<li>inHg<\/li>\n<li>inH\u2082O<\/li>\n<li>mmH\u2082O<\/li>\n<li>cmH\u2082O<\/li>\n<li>kgf\/cm\u00b2<\/li>\n<li>torr<\/li>\n<li>Custom units<\/li>\n<\/ul>\n<p>This allows the calibrator to be adapted easily to different industrial and laboratory applications.<\/p>\n<h2>Integrated Electrical Measurement<\/h2>\n<p>In addition to pressure generation and measurement, the <strong>Additel ADT 760A-D<\/strong> provides integrated electrical process calibration functions.<\/p>\n<p>This makes it possible to evaluate both the pressure input and electrical output of a pressure transmitter using one instrument.<\/p>\n<h3>Current Measurement<\/h3>\n<p>The ADT 760A-D measures:<\/p>\n<p><strong>\u00b130 mA<\/strong><\/p>\n<p>with a resolution of:<\/p>\n<p><strong>0.0001 mA<\/strong><\/p>\n<p>and an accuracy of:<\/p>\n<p><strong>0.01 % of reading + 1.5 \u00b5A<\/strong><\/p>\n<p>This is particularly useful for calibration of conventional:<\/p>\n<p><strong>4\u201320 mA pressure transmitters<\/strong><\/p>\n<h2>Voltage Measurement<\/h2>\n<p>The calibrator can measure voltage over a range of:<\/p>\n<p><strong>\u00b130 V<\/strong><\/p>\n<p>with a resolution of:<\/p>\n<p><strong>0.0001 V<\/strong><\/p>\n<p>The specified voltage measurement accuracy is:<\/p>\n<p><strong>0.01 % of reading + 1.5 mV<\/strong><\/p>\n<p>This provides additional flexibility for process instrumentation and sensor calibration.<\/p>\n<h2>Current Source<\/h2>\n<p>The ADT 760A-D can also source current up to:<\/p>\n<p><strong>24 mA<\/strong><\/p>\n<p>with a resolution of:<\/p>\n<p><strong>0.001 mA<\/strong><\/p>\n<p>This allows the instrument to simulate process current signals when testing control systems, indicators and other process equipment.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>An integrated:<\/p>\n<p><strong>24 V loop power supply<\/strong><\/p>\n<p>is available for powering process transmitters during calibration.<\/p>\n<p>The maximum load is specified as:<\/p>\n<p><strong>50 mA<\/strong><\/p>\n<p>This allows a pressure transmitter to be powered and measured directly by the ADT 760A-D without requiring a separate loop power supply.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>The ADT 760A-D supports automated:<\/p>\n<p><strong>pressure switch testing<\/strong><\/p>\n<p>Mechanical pressure switches as well as NPN and PNP digital switches are supported.<\/p>\n<p>The calibrator can determine switching points while automatically generating and controlling the applied pressure.<\/p>\n<p>This can considerably simplify pressure switch calibration compared with a completely manual test setup.<\/p>\n<h2>Automatic Step Function<\/h2>\n<p>The integrated automation functions include:<\/p>\n<p><strong>Auto Step<\/strong><\/p>\n<p>Pressure points can therefore be approached automatically according to a predefined sequence.<\/p>\n<p>This is useful for calibrations requiring several increasing and decreasing pressure points.<\/p>\n<p>Instead of manually pumping and adjusting each point, the ADT 760A-D automatically generates the requested reference pressures.<\/p>\n<h2>Leak Testing<\/h2>\n<p>The ADT 760A-D also includes a:<\/p>\n<p><strong>Leak Test<\/strong><\/p>\n<p>function.<\/p>\n<p>A stable pressure can be generated and the subsequent pressure change monitored over a defined period.<\/p>\n<p>This function is useful for evaluating:<\/p>\n<ul>\n<li>Pressure connections<\/li>\n<li>Tubing<\/li>\n<li>Adapters<\/li>\n<li>Test setups<\/li>\n<li>Pressure instruments<\/li>\n<\/ul>\n<p>before beginning a precision calibration.<\/p>\n<h2>Four Measurement Channels<\/h2>\n<p>The ADT760A platform provides four channels:<\/p>\n<ul>\n<li>One internal pressure channel<\/li>\n<li>Two external pressure measurement channels<\/li>\n<li>One electrical measurement\/source channel<\/li>\n<\/ul>\n<p>The external pressure channels allow compatible external Additel pressure modules to be connected.<\/p>\n<p>This significantly extends the measurement capability of the handheld calibrator beyond its internal pressure module.<\/p>\n<h2>4.95-Inch Touchscreen<\/h2>\n<p>The new ADT760A generation features a:<\/p>\n<p><strong>4.95-inch color touchscreen<\/strong><\/p>\n<p>with a resolution of:<\/p>\n<p><strong>854 \u00d7 480 pixels<\/strong><\/p>\n<p>The capacitive touchscreen provides a modern smartphone-like user interface for setting pressure values, configuring calibration functions and viewing measurement results.<\/p>\n<p>The interface supports multiple languages, including:<\/p>\n<ul>\n<li>English<\/li>\n<li>German<\/li>\n<li>French<\/li>\n<li>Italian<\/li>\n<li>Spanish<\/li>\n<li>Portuguese<\/li>\n<li>Chinese<\/li>\n<li>Japanese<\/li>\n<li>Russian<\/li>\n<\/ul>\n<h2>Bluetooth, Wi-Fi and USB<\/h2>\n<p>The <strong>Additel ADT 760A-D<\/strong> supports modern communication interfaces including:<\/p>\n<p><strong>Bluetooth<\/strong><\/p>\n<p><strong>Wi-Fi<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>USB<\/strong><\/p>\n<p>These communication options allow the instrument to be integrated into digital calibration and documentation workflows.<\/p>\n<p>Compatible Additel software includes solutions such as ACal, Land and LogII.<\/p>\n<h2>Optional HART Communication<\/h2>\n<p>For applications requiring communication with intelligent process transmitters, Additel offers the corresponding:<\/p>\n<p><strong>ADT 760A-D-DL<\/strong><\/p>\n<p>configuration.<\/p>\n<p>The DL version adds a full:<\/p>\n<p><strong>HART field communicator<\/strong><\/p>\n<p>This allows direct communication with compatible HART transmitters.<\/p>\n<p>HART capability is particularly valuable when commissioning, configuring, diagnosing and calibrating smart pressure transmitters.<\/p>\n<h2>Optional Data Logging and Tasks<\/h2>\n<p>The corresponding DL configuration also provides data logging and task documentation.<\/p>\n<p>Data logging capacity is up to:<\/p>\n<p><strong>1,000,000 readings<\/strong><\/p>\n<p>with date and time information.<\/p>\n<p>Task documentation supports up to:<\/p>\n<p><strong>1,000 tasks<\/strong><\/p>\n<p>These functions are particularly useful for organized field calibration and digital documentation workflows.<\/p>\n<h2>Optional Contamination Prevention System<\/h2>\n<p>A new optional <strong>Contamination Prevention System (CPS)<\/strong> is available for the ADT760A series.<\/p>\n<p>The CPS is designed to help protect the internal pneumatic components from contamination entering through connected devices or pressure lines.<\/p>\n<p>This can be particularly useful when calibrating process instruments that may contain:<\/p>\n<ul>\n<li>Oil<\/li>\n<li>Moisture<\/li>\n<li>Dirt<\/li>\n<li>Process residues<\/li>\n<li>Other contaminants<\/li>\n<\/ul>\n<p>Protecting the internal pneumatic system can reduce maintenance requirements and improve long-term reliability.<\/p>\n<h2>Portable Handheld Design<\/h2>\n<p>Despite integrating a pressure pump, controller, pressure measurement system and electrical process calibrator, the ADT 760A-D weighs approximately:<\/p>\n<p><strong>1.8 kg \/ 4 lb<\/strong><\/p>\n<p>Dimensions are approximately:<\/p>\n<p><strong>235 \u00d7 110 \u00d7 70 mm<\/strong><\/p>\n<p>This compact format makes the ADT 760A-D particularly suitable for field calibration and maintenance work.<\/p>\n<h2>Rechargeable Battery<\/h2>\n<p>The instrument uses a rechargeable:<\/p>\n<p><strong>Li-ion battery<\/strong><\/p>\n<p>Typical operating time is approximately:<\/p>\n<p><strong>10 hours<\/strong><\/p>\n<p>and charging time is less than:<\/p>\n<p><strong>4 hours<\/strong><\/p>\n<p>This allows the ADT 760A-D to be used throughout a typical working day without permanent connection to an external power supply.<\/p>\n<h2>Robust Design for Field Calibration<\/h2>\n<p>The enclosure is rated:<\/p>\n<p><strong>IP52<\/strong><\/p>\n<p>The specified operating conditions are:<\/p>\n<p><strong>Temperature: 0 to 50 \u00b0C<\/strong><\/p>\n<p><strong>Relative humidity: 0 to 90 % RH<\/strong><\/p>\n<p><strong>Altitude: below 3,000 m<\/strong><\/p>\n<p>The instrument is also designed to withstand vibration and shock associated with portable field use.<\/p>\n<h2>Long Pump Life<\/h2>\n<p>Additel specifies a pump life of more than:<\/p>\n<p><strong>500,000 cycles<\/strong><\/p>\n<p>This is particularly important for an automatic handheld pressure calibrator because the internal electric pump performs the pressure generation that would otherwise be carried out manually.<\/p>\n<h2>ISO\/IEC 17025
