configurations.<\/p>\n<h3>ADT 780-1K<\/h3>\n<p>The ADT 780-1K provides a pressure range of:<\/p>\n<p><strong>-14.5 to 1,000 psi<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>-0.95 to 70 bar<\/strong><\/p>\n<p>This configuration is particularly suitable for common industrial pressure calibration applications.<\/p>\n<h3>ADT 780-3K<\/h3>\n<p>The ADT 780-3K extends the pressure capability to:<\/p>\n<p><strong>-14.5 to 3,000 psi<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>-0.95 to 200 bar<\/strong><\/p>\n<p>The higher-pressure configuration requires an appropriate high-pressure gas supply to reach the full 3,000 psi \/ 200 bar range.<\/p>\n<p>The two configurations allow laboratories to select the pressure controller that best matches their calibration workload.<\/p>\n<h2>Gauge and Absolute Pressure<\/h2>\n<p>The <strong>Additel ADT 780 Pressure Controller<\/strong> supports:<\/p>\n<p><strong>Gauge Pressure<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Absolute Pressure<\/strong><\/p>\n<p>Gauge pressure is measured relative to atmospheric pressure:<\/p>\n<p><strong>pGauge = pAbsolute &#8211; pAtmosphere<\/strong><\/p>\n<p>The ADT780 incorporates a built-in barometric sensor, allowing the system to switch between gauge and absolute pressure measurements.<\/p>\n<p>This provides considerable flexibility for laboratories calibrating different types of pressure instruments.<\/p>\n<h2>Modular Pressure Measurement System<\/h2>\n<p>One of the most important features of the ADT 780 is its modular architecture.<\/p>\n<p>The system supports:<\/p>\n<p><strong>one internal Intelligent Pressure Module<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>one external Intelligent Pressure Module<\/strong><\/p>\n<p>The internal and external pressure sensors can be exchanged for compatible modules.<\/p>\n<p>This allows the pressure controller to be adapted to different pressure ranges and metrological requirements.<\/p>\n<p>A laboratory can therefore configure the ADT 780 according to the devices being calibrated instead of relying exclusively on a single pressure range.<\/p>\n<h2>Standard Accuracy of 0.02 % FS<\/h2>\n<p>Standard pressure sensor configurations provide a one-year accuracy specification of:<\/p>\n<p><strong>0.02 % FS<\/strong><\/p>\n<p>FS means Full Scale.<\/p>\n<p>For a full-scale-based accuracy specification, the absolute contribution depends on the measuring range of the installed pressure module.<\/p>\n<p>Selecting a reference module with a range appropriately matched to the device under test is therefore important when optimizing calibration capability.<\/p>\n<h2>High-Accuracy Pressure Modules<\/h2>\n<p>Higher-performance pressure modules are available for applications requiring improved measurement capability.<\/p>\n<p>Depending on the selected module generation and pressure range, Additel provides high-accuracy configurations with specifications based on percentage of reading and full scale.<\/p>\n<p>This is particularly advantageous when one controller is used over a wide range of pressures.<\/p>\n<p>The exact accuracy specification should therefore always be evaluated for the specific pressure module installed in the ADT 780.<\/p>\n<h2>Pressure Control Stability<\/h2>\n<p>The pressure control stability of the <strong>Additel ADT 780<\/strong> is specified as:<\/p>\n<p><strong>0.003 % FS<\/strong><\/p>\n<p>The stability specification is based on the full scale of the installed control sensor.<\/p>\n<p>Stable pressure control is important for calibration because the reference pressure should remain sufficiently stable while the device under test is read and documented.<\/p>\n<p>This is particularly important when calibrating high-resolution digital pressure instruments.<\/p>\n<h2>User-Selectable Resolution<\/h2>\n<p>The ADT 780 provides user-selectable pressure resolution of:<\/p>\n<p><strong>4, 5, 6 or 7 digits<\/strong><\/p>\n<p>depending on the pressure module configuration.<\/p>\n<p>Seven-digit resolution is associated with suitable precision pressure modules.<\/p>\n<p>The selectable display resolution allows the indication to be adapted to the measurement task.<\/p>\n<h2>Minimum Controllable Pressure<\/h2>\n<p>The minimum controllable pressure depends on the installed pressure module and controller configuration.<\/p>\n<p>For the ADT 780-1K, Additel specifies a minimum control pressure down to:<\/p>\n<p><strong>0.0001 psi<\/strong><\/p>\n<p>For the ADT 780-3K, the specified value is:<\/p>\n<p><strong>0.001 psi<\/strong><\/p>\n<p>The actual useful calibration range must nevertheless be evaluated together with the accuracy and uncertainty of the installed pressure module.<\/p>\n<h2>Optional Electric Pump<\/h2>\n<p>A particularly useful feature of the <strong>ADT 780-1K<\/strong> is the optional electric pressure pump.<\/p>\n<p>With the:<\/p>\n<p><strong>ADT780-1K-EPUMP<\/strong><\/p>\n<p>the controller can generate pressures up to:<\/p>\n<p><strong>1,000 psi \/ 70 bar<\/strong><\/p>\n<p>without requiring an external compressed-gas cylinder.<\/p>\n<p>This transforms the ADT 780-1K into a highly integrated standalone automatic pressure calibration system.<\/p>\n<h2>Standalone Pressure Generation up to 70 bar<\/h2>\n<p>Traditional pneumatic pressure controllers typically require an external nitrogen or compressed-gas supply.<\/p>\n<p>With the optional electric pump, the ADT 780-1K can generate its own pressure up to 70 bar.<\/p>\n<p>This can simplify:<\/p>\n<ul>\n<li>Laboratory installations<\/li>\n<li>Mobile calibration systems<\/li>\n<li>Calibration carts<\/li>\n<li>Temporary calibration setups<\/li>\n<li>Production test stations<\/li>\n<\/ul>\n<p>It also eliminates the need to move or connect a high-pressure gas cylinder for applications within the electric pump&#8217;s operating range.<\/p>\n<h2>ADT 780-3K up to 200 bar<\/h2>\n<p>For higher pressure applications, the <strong>ADT 780-3K<\/strong> extends the pneumatic control range to:<\/p>\n<p><strong>200 bar \/ 3,000 psi<\/strong><\/p>\n<p>An appropriate high-pressure gas supply is required to achieve the full pressure range.<\/p>\n<p>This makes the ADT 780-3K suitable for calibration of industrial pressure instruments with measuring ranges substantially above the 70 bar capability of the ADT 780-1K.<\/p>\n<h2>Clean Gas Pressure Medium<\/h2>\n<p>Additel specifies:<\/p>\n<p><strong>Clean gas<\/strong><\/p>\n<p>as the pressure medium.<\/p>\n<p>Clean pneumatic operation helps protect:<\/p>\n<ul>\n<li>Internal control valves<\/li>\n<li>Pressure modules<\/li>\n<li>Pressure lines<\/li>\n<li>Reference sensors<\/li>\n<li>Devices under test<\/li>\n<\/ul>\n<p>Suitable contamination control is particularly important when different customer instruments are repeatedly connected to the same pressure controller.<\/p>\n<h2>Integrated Process Calibrator Functions<\/h2>\n<p>The ADT 780 differs from the simplified ADT 780S by providing extensive electrical process calibration functionality.<\/p>\n<p>The ADT 780 includes capabilities for:<\/p>\n<ul>\n<li>Current measurement<\/li>\n<li>Voltage measurement<\/li>\n<li>Millivolt measurement<\/li>\n<li>24 V loop power<\/li>\n<li>Pressure switch measurement<\/li>\n<li>HART communication<\/li>\n<li>PROFIBUS PA communication<\/li>\n<\/ul>\n<p>This combination allows the ADT 780 to perform many pressure transmitter calibration tasks without requiring several separate instruments.<\/p>\n<h2>Current and Voltage Measurement<\/h2>\n<p>The integrated calibrator function can measure electrical signals associated with pressure transmitters and sensors.<\/p>\n<p>Available measurement functions include:<\/p>\n<p><strong>Current<\/strong><\/p>\n<p><strong>Voltage<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Millivolts<\/strong><\/p>\n<p>This allows the pneumatic input pressure and electrical output of a pressure transmitter to be evaluated within the same calibration system.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>The ADT 780 provides:<\/p>\n<p><strong>24 V loop power<\/strong><\/p>\n<p>for compatible process transmitters.<\/p>\n<p>A two-wire pressure transmitter can therefore be supplied directly during calibration.<\/p>\n<p>Combined with automatic pressure control and current measurement, this creates an efficient setup for 4\u201320 mA pressure transmitter calibration.<\/p>\n<h2>HART Communication<\/h2>\n<p>The <strong>Additel ADT 780<\/strong> supports:<\/p>\n<p><strong>HART communication<\/strong><\/p>\n<p>for compatible smart process instruments.<\/p>\n<p>HART capability can simplify calibration and service work on smart pressure transmitters by combining digital communication with the pneumatic calibration process.<\/p>\n<h2>PROFIBUS PA Communication<\/h2>\n<p>The ADT 780 also supports:<\/p>\n<p><strong>PROFIBUS PA<\/strong><\/p>\n<p>communication.<\/p>\n<p>This extends the system&#8217;s capabilities to compatible digital process instrumentation and makes the controller useful in industrial process calibration environments.<\/p>\n<h2>Pressure Switch Testing<\/h2>\n<p>Pressure switches can be tested using the integrated switch measurement functionality.<\/p>\n<p>During a pressure switch test, the ADT 780 can record the pressure at which the switch:<\/p>\n<p><strong>Sets<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Resets<\/strong><\/p>\n<p>This enables parameters such as switching pressure and hysteresis to be evaluated.<\/p>\n<p>Automatic pressure control can make these tests considerably easier and more repeatable than manual pressure generation.<\/p>\n<h2>Pressure Transmitter Calibration<\/h2>\n<p>The combination of automatic pressure control and electrical process measurement makes the ADT 780 particularly suitable for pressure transmitter calibration.<\/p>\n<p>A typical 4\u201320 mA transmitter calibration can include:<\/p>\n<ol start=\"1\">\n<li>Supplying the transmitter with 24 V loop power<\/li>\n<li>Generating the required reference pressure<\/li>\n<li>Stabilizing the pressure<\/li>\n<li>Measuring the transmitter current<\/li>\n<li>Recording the pressure and electrical values<\/li>\n<li>Repeating the procedure at several pressure points<\/li>\n<\/ol>\n<p>This integrated approach reduces the amount of external equipment required for the calibration.<\/p>\n<h2>Digital Pressure Gauge Calibration<\/h2>\n<p>The <strong>Additel ADT 780 Pressure Controller<\/strong> is also suitable for calibrating digital pressure gauges.<\/p>\n<p>The controller generates and stabilizes the required reference pressure while the indication of the device under test is compared with the ADT 780 reference measurement.<\/p>\n<p>Typical calibration sequences include increasing and decreasing pressure points to evaluate:<\/p>\n<ul>\n<li>Indication error<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Zero behavior<\/li>\n<\/ul>\n<h2>Pressure Sensor Calibration<\/h2>\n<p>Industrial pressure sensors and transducers can also be calibrated using the ADT 780.<\/p>\n<p>The modular pressure sensor architecture allows the reference range to be selected according to the pressure range of the device under test.<\/p>\n<p>This is especially useful for laboratories handling many different sensor ranges.<\/p>\n<h2>Large 7-Inch Touchscreen<\/h2>\n<p>The ADT 780 uses a large:<\/p>\n<p><strong>7-inch color touchscreen<\/strong><\/p>\n<p>with an icon-based user interface.<\/p>\n<p>The touchscreen provides access to pressure measurement, control and process calibration functions.<\/p>\n<p>The large display makes the controller suitable for stationary laboratory operation and automated calibration workstations.<\/p>\n<h2>Wide Selection of Pressure Units<\/h2>\n<p>The ADT 780 supports numerous pressure units, 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>mHg<\/li>\n<li>inHg<\/li>\n<li>inH\u2082O<\/li>\n<li>mmH\u2082O<\/li>\n<li>cmH\u2082O<\/li>\n<li>kg\/cm\u00b2<\/li>\n<li>torr<\/li>\n<li>mtorr<\/li>\n<li>atm<\/li>\n<\/ul>\n<p>User-selectable units simplify operation when calibrating instruments with different engineering units.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> Additel ADT 780<\/p>\n<p><strong>Device
