integrated data logging<\/li>\n<li>No DL version<\/li>\n<\/ul>\n<h2>Automatic Pressure Generation from Vacuum to 25 bar<\/h2>\n<p>The <strong>Additel ADT 760S-MA<\/strong> provides the highest pressure generation capability within the ADT760S handheld series.<\/p>\n<p>Its pressure range extends from:<\/p>\n<p><strong>-0.86 to 25 bar(g)<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>-86 to 2,500 kPa(g)<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>-12.5 to 375 psig<\/strong><\/p>\n<p>The negative pressure capability allows vacuum relative to atmospheric pressure to be generated, while the integrated electric pump generates positive pneumatic pressure up to 25 bar.<\/p>\n<p>This wide pressure range makes the ADT 760S-MA suitable for many industrial pressure calibration applications without requiring an external hand pump or pressure source.<\/p>\n<h2>Fully Automatic Pressure Control<\/h2>\n<p>One of the major advantages of the <strong>Additel ADT 760S-MA<\/strong> is its fully automatic pressure generation.<\/p>\n<p>A conventional pressure calibration setup may require:<\/p>\n<ul>\n<li>Manual pressure pump<\/li>\n<li>Precision reference pressure gauge<\/li>\n<li>Fine pressure adjustment valve<\/li>\n<li>Pressure tubing<\/li>\n<li>Pressure adapters<\/li>\n<li>Additional pressure control components<\/li>\n<\/ul>\n<p>The ADT 760S-MA combines pressure generation, reference pressure measurement and automatic pressure control in one compact instrument.<\/p>\n<p>The operator enters the required pressure setpoint and the integrated electric pump automatically generates the pressure.<\/p>\n<p>The closed-loop pressure controller then regulates the pressure until the required setpoint is reached and stabilized.<\/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 ADT155 internal pressure module, the <strong>Additel ADT 760S-MA<\/strong> 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 installed pressure module.<\/p>\n<p>This is an important consideration when selecting the appropriate internal module.<\/p>\n<p>Using a pressure module that is closely matched to the actual calibration range can improve absolute measurement performance compared with using the maximum 25 bar module for substantially lower pressures.<\/p>\n<h2>Pressure Control Stability<\/h2>\n<p>The specified pressure control 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 useful during multipoint calibration because the device under test can be evaluated after the reference pressure has automatically reached a stable condition.<\/p>\n<h2>Gauge Pressure Measurement<\/h2>\n<p>The <strong>Additel ADT 760S-MA<\/strong> supports:<\/p>\n<p><strong>Gauge Pressure<\/strong><\/p>\n<p>Gauge pressure is measured relative to the surrounding atmospheric pressure.<\/p>\n<p>The relationship can be expressed approximately as:<\/p>\n<p><strong>p_gauge = p_absolute &#8211; p_atmosphere<\/strong><\/p>\n<p>A gauge pressure of zero therefore corresponds approximately to the current atmospheric pressure.<\/p>\n<p>Gauge pressure is commonly used for:<\/p>\n<ul>\n<li>Industrial pressure gauges<\/li>\n<li>Pressure transmitters<\/li>\n<li>Pressure sensors<\/li>\n<li>Pressure switches<\/li>\n<li>Pneumatic process instrumentation<\/li>\n<\/ul>\n<h2>Absolute Pressure Measurement<\/h2>\n<p>The MA version also supports:<\/p>\n<p><strong>Absolute Pressure<\/strong><\/p>\n<p>Absolute pressure is referenced to an ideal vacuum.<\/p>\n<p>The approximate relationship is:<\/p>\n<p><strong>p_absolute = p_gauge + p_atmosphere<\/strong><\/p>\n<p>To calculate absolute pressure accurately from a gauge pressure measurement, the current atmospheric pressure must therefore be known.<\/p>\n<p>The ADT 760S-MA solves this by incorporating its own barometric reference.<\/p>\n<h2>Integrated Barometric Reference<\/h2>\n<p>The <strong>Additel ADT 760S-MA<\/strong> includes a built-in:<\/p>\n<p><strong>barometric reference<\/strong><\/p>\n<p>This enables the instrument to switch between gauge and absolute pressure measurement.<\/p>\n<p>This capability is one of the most important differences between the MA configuration and the D or LLP configurations.<\/p>\n<p>For absolute pressure measurement, Additel specifies that an additional:<\/p>\n<p><strong>55 Pa uncertainty<\/strong><\/p>\n<p>must be included.<\/p>\n<p>This additional contribution is associated with the barometric reference and should be considered when evaluating the complete measurement uncertainty in absolute pressure mode.<\/p>\n<h2>Interchangeable ADT155 Pressure Modules<\/h2>\n<p>The ADT 760S-MA uses interchangeable internal:<\/p>\n<p><strong>Additel ADT155 pressure modules<\/strong><\/p>\n<p>The maximum MA configuration provides pressure generation and measurement up to:<\/p>\n<p><strong>25 bar \/ 375 psi<\/strong><\/p>\n<p>Additional internal sensors with lower pressure ranges are available.<\/p>\n<p>Selecting a lower-range pressure module can provide improved measurement performance when the calibration application does not require the complete 25 bar range.<\/p>\n<p>The interchangeable sensor concept also provides greater flexibility than an instrument with only one permanently installed pressure range.<\/p>\n<h2>Six-Digit Pressure Resolution<\/h2>\n<p>The ADT760S platform provides:<\/p>\n<p><strong>6-digit pressure resolution<\/strong><\/p>\n<p>A wide range of pressure units is available, 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>torr<\/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>Custom units<\/li>\n<\/ul>\n<p>This makes the ADT 760S-MA suitable for international calibration applications and different industrial pressure measurement conventions.<\/p>\n<h2>Two External Pressure Module Channels<\/h2>\n<p>In addition to the interchangeable internal ADT155 module, the ADT760S platform supports:<\/p>\n<p><strong>two external pressure module channels<\/strong><\/p>\n<p>Compatible Additel external pressure modules can therefore be connected for additional pressure measurement applications.<\/p>\n<p>This expands the measurement flexibility of the instrument beyond the installed internal pressure module.<\/p>\n<p>The external measurement channels do not, however, extend the pressure generation capability of the internal pneumatic system.<\/p>\n<h2>ADT 760S-MA \u2013 Pressure-Focused Design<\/h2>\n<p>The <strong>Additel ADT 760S-MA<\/strong> is designed for applications where automatic pressure generation and precision pressure measurement are the primary requirements.<\/p>\n<p>Additel describes the ADT760S as the streamlined version of the ADT760A platform.<\/p>\n<p>The ADT 760S provides the same pressure ranges and pressure accuracy as the corresponding ADT 760A but does not include its electrical ports or integrated device communication functions.<\/p>\n<p>This makes the ADT 760S-MA particularly useful as a:<\/p>\n<p><strong>portable automatic pressure source<\/strong><\/p>\n<p>for calibration laboratories and field applications.<\/p>\n<h2>No Integrated Electrical Measurement<\/h2>\n<p>Unlike the <strong>ADT 760A-MA<\/strong>, the <strong>ADT 760S-MA does not provide integrated electrical process calibration ports<\/strong>.<\/p>\n<p>The ADT 760S-MA should therefore not be specified with functions such as:<\/p>\n<ul>\n<li>Integrated mA measurement<\/li>\n<li>Integrated voltage measurement<\/li>\n<li>24 mA source\/simulation<\/li>\n<li>24 V loop power<\/li>\n<li>Integrated pressure switch electrical testing<\/li>\n<\/ul>\n<p>These functions belong to the ADT760A process calibrator platform.<\/p>\n<p>When electrical measurements are required, the ADT 760S-MA can be combined with a separate electrical reference instrument.<\/p>\n<h2>Ideal for Use with External Electrical References<\/h2>\n<p>A typical example is the calibration of a:<\/p>\n<p><strong>4\u201320 mA pressure transmitter<\/strong><\/p>\n<p>The ADT 760S-MA can automatically generate and measure the required reference pressure.<\/p>\n<p>The transmitter output can then be measured separately using a:<\/p>\n<ul>\n<li>Precision digital multimeter<\/li>\n<li>Process calibrator<\/li>\n<li>Electrical reference instrument<\/li>\n<li>Data acquisition system<\/li>\n<\/ul>\n<p>This configuration can be particularly attractive for professional calibration laboratories that already have high-accuracy electrical measurement equipment.<\/p>\n<h2>No HART Field Communicator<\/h2>\n<p>The <strong>ADT 760S-MA does not provide an integrated HART Field Communicator<\/strong>.<\/p>\n<p>HART functionality is available with the appropriate DL configurations of the ADT760A platform.<\/p>\n<p>Users requiring communication, configuration or diagnostics of smart HART pressure transmitters should therefore select the corresponding ADT760A model.<\/p>\n<h2>No Integrated Data Logging<\/h2>\n<p>The ADT 760S-MA should also be distinguished from the documenting functionality of the ADT760A.<\/p>\n<p>Integrated:<\/p>\n<p><strong>Data Logging<\/strong><\/p>\n<p>is only available on ADT760A models.<\/p>\n<p>It should therefore not be listed as a standard feature of the ADT 760S-MA.<\/p>\n<h2>No ADT 760S-MA-DL Version<\/h2>\n<p>The ADT760S family consists of:<\/p>\n<ul>\n<li>ADT 760S-LLP<\/li>\n<li>ADT 760S-D<\/li>\n<li>ADT 760S-MA<\/li>\n<\/ul>\n<p>There are no corresponding ADT760S-DL configurations.<\/p>\n<p>Customers requiring HART communication, task documentation or integrated data logging should select the appropriate ADT760A-DL model.<\/p>\n<h2>Built-In Filter and Liquid Trap<\/h2>\n<p>The ADT760A\/760S platform includes:<\/p>\n<p><strong>a built-in filter<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>a built-in liquid trap<\/strong><\/p>\n<p>These components help protect the internal pneumatic system against contamination entering from the device under test or pressure lines.<\/p>\n<p>This is particularly useful for field calibration, where connected instruments may have previously been exposed to industrial processes.<\/p>\n<h2>Optional Contamination Prevention System<\/h2>\n<p>An optional:<\/p>\n<p><strong>Contamination Prevention System \u2013 CPS<\/strong><\/p>\n<p>is available for the ADT760A\/760S platform.<\/p>\n<p>The CPS provides additional protection for the internal pneumatic components.<\/p>\n<p>Potential contaminants can include:<\/p>\n<ul>\n<li>Oil<\/li>\n<li>Moisture<\/li>\n<li>Dirt<\/li>\n<li>Particles<\/li>\n<li>Process residues<\/li>\n<\/ul>\n<p>Protecting the internal pump, pressure module and control system can contribute to reliable long-term operation.<\/p>\n<h2>Modern Touchscreen Operation<\/h2>\n<p>The ADT760S platform features a large capacitive touchscreen.<\/p>\n<p>Pressure setpoints can be entered directly through the user interface.<\/p>\n<p>The automatic controller then generates and stabilizes the requested pressure.<\/p>\n<p>This is particularly convenient during multipoint calibration because the operator no longer has to manually pump and finely adjust each pressure point.<\/p>\n<h2>Bluetooth, Wi-Fi and USB<\/h2>\n<p>The <strong>Additel ADT 760S-MA<\/strong> supports:<\/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>communication.<\/p>\n<p>These interfaces provide flexible connectivity for supported software interaction, instrument operation and maintenance.<\/p>\n<p>The availability of these interfaces should not be confused with the integrated process-device communication capabilities of the ADT760A-DL versions.<\/p>\n<h2>Compact Handheld Design<\/h2>\n<p>The ADT760S platform weighs less than:<\/p>\n<p><strong>4 lb \/ 1.8 kg<\/strong><\/p>\n<p>This makes the ADT 760S-MA suitable for both laboratory and mobile field calibration.<\/p>\n<p>Its combination of:<\/p>\n<ul>\n<li>Integrated electric pressure pump<\/li>\n<li>Automatic pressure controller<\/li>\n<li>Precision pressure measurement<\/li>\n<li>Interchangeable internal pressure module<\/li>\n<li>Barometric reference<\/li>\n<li>External pressure module

calibration of an automatic pressure calibrator is important for maintaining reliable metrological performance.<\/p>\n<p>This is particularly relevant for the MA configuration because absolute pressure measurements combine the internal gauge pressure measurement with information from the barometric reference.<\/p>\n<p>The <a href=\"https:\/\/europascal.de\/en\/calibration-services\/\">europascal calibration service<\/a> provides professional calibration solutions for automatic pressure calibrators, pressure controllers, pressure modules, digital pressure gauges, pressure transmitters and pressure sensors.<\/p>\n<p>europascal can also support customers in selecting the appropriate ADT155 internal pressure module, pressure range and accessories.<\/p>\n<h2>Why Choose the Additel ADT 760S-MA?<\/h2>\n<p>The <strong>Additel ADT 760S-MA Precise Automatic Pressure Calibrator<\/strong> combines automatic pneumatic pressure generation from <strong>-0.86 to 25 bar<\/strong>, pressure accuracy down to <strong>0.01 % FS<\/strong>, <strong>0.005 % FS control stability<\/strong> and an integrated barometric reference in one compact handheld instrument.<\/p>\n<p>Its ability to operate with both <strong>gauge and absolute pressure<\/strong> makes the MA configuration particularly versatile for industrial and laboratory pressure calibration.<\/p>\n<p>Interchangeable ADT155 internal pressure modules and two external pressure measurement channels provide additional flexibility for different pressure ranges.<\/p>\n<p>Most importantly, the ADT 760S-MA provides the pressure performance of the ADT760A platform without the integrated electrical process calibration and advanced device communication
