included<\/li>\n<\/ul>\n<h2>Pressure Ranges up to 4,200 bar<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> is available in an exceptionally broad selection of pressure ranges.<\/p>\n<p>The product family extends from low and differential pressure ranges to:<\/p>\n<p><strong>60,000 psi \/ 4,200 bar<\/strong>.<\/p>\n<p>This allows the ADT 673 platform to cover applications ranging from process pressure measurement through hydraulic high-pressure calibration.<\/p>\n<p>Depending on the selected configuration, the instrument can measure:<\/p>\n<ul>\n<li>Gauge pressure<\/li>\n<li>Compound pressure<\/li>\n<li>Absolute pressure<\/li>\n<li>Differential pressure<\/li>\n<li>Barometric pressure<\/li>\n<\/ul>\n<p>This broad selection allows users to select a pressure range that closely matches the device under test rather than using one oversized pressure range for every application.<\/p>\n<h2>Accuracy Down to 0.02% FS<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> is available with several accuracy options depending on the selected pressure range.<\/p>\n<p>The ADT673-02 provides accuracy of:<\/p>\n<p><strong>0.02% of full span<\/strong><\/p>\n<p>while the ADT673-05 provides:<\/p>\n<p><strong>0.05% of full span<\/strong>.<\/p>\n<p>Additel also offers the ADT673-RD specification.<\/p>\n<p>For this version, accuracy is specified as:<\/p>\n<p><strong>0 to 20% of range: 0.02% FS<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>20 to 110% of range: 0.1% of reading<\/strong>.<\/p>\n<p>The availability of different accuracy classes allows the ADT 673 to be configured according to the actual calibration requirement.<\/p>\n<h2>Fully Temperature Compensated<\/h2>\n<p>Pressure sensor performance can be influenced by ambient temperature.<\/p>\n<p>The <strong>Additel ADT 673<\/strong> is therefore fully temperature compensated over the range:<\/p>\n<p><strong>-10 \u00b0C to 50 \u00b0C<\/strong>.<\/p>\n<p>This broad compensated temperature range is particularly valuable for field calibration.<\/p>\n<p>Pressure measurements can therefore be performed under changing environmental conditions while maintaining the specified measurement performance.<\/p>\n<p>The operating temperature range is also -10 \u00b0C to 50 \u00b0C, while the storage temperature range extends from -30 \u00b0C to 70 \u00b0C.<\/p>\n<h2>Gauge Pressure Measurement<\/h2>\n<p>The Additel ADT 673 provides a broad selection of gauge pressure ranges.<\/p>\n<p>Depending on the selected range, the pressure medium can be gas or liquid.<\/p>\n<p>At pressures above 1,000 psi, the corresponding configurations use sealed gauge pressure measurement.<\/p>\n<p>Gauge pressure applications include:<\/p>\n<ul>\n<li>Pressure gauge calibration<\/li>\n<li>Pressure transmitter calibration<\/li>\n<li>Pressure sensor testing<\/li>\n<li>Pressure switch testing<\/li>\n<li>Hydraulic pressure measurement<\/li>\n<li>Pneumatic pressure measurement<\/li>\n<li>Process pressure monitoring<\/li>\n<\/ul>\n<h2>Compound Pressure Measurement<\/h2>\n<p>Compound pressure versions of the <strong>Additel ADT 673<\/strong> combine negative and positive gauge pressure measurement within one instrument.<\/p>\n<p>Available compound ranges extend from vacuum into positive pressure ranges.<\/p>\n<p>This is particularly useful when calibrating devices that operate on both sides of atmospheric pressure.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Compound pressure gauges<\/li>\n<li>Process transmitters<\/li>\n<li>Vacuum and pressure sensors<\/li>\n<li>Industrial process instrumentation<\/li>\n<\/ul>\n<p>The use of one compound pressure calibrator can reduce the need to switch between separate vacuum and positive pressure reference instruments.<\/p>\n<h2>Differential Pressure Measurement<\/h2>\n<p>The ADT 673 is also available in dedicated differential pressure configurations.<\/p>\n<p>Differential ranges extend from very low pressure differences upward.<\/p>\n<p>Depending on the selected range, accuracy is available down to:<\/p>\n<p><strong>0.02% FS<\/strong>.<\/p>\n<p>Typical differential pressure applications include:<\/p>\n<ul>\n<li>Differential pressure transmitters<\/li>\n<li>Flow measurement<\/li>\n<li>Filter monitoring<\/li>\n<li>HVAC systems<\/li>\n<li>Process instrumentation<\/li>\n<li>Low-pressure measurement<\/li>\n<\/ul>\n<p>This expands the ADT 673 beyond conventional gauge pressure calibration.<\/p>\n<h2>Built-in Barometer<\/h2>\n<p>Every <strong>Additel ADT 673<\/strong> includes a built-in barometric pressure sensor.<\/p>\n<p>The standard built-in barometer provides an accuracy specification of:<\/p>\n<p><strong>55 Pa<\/strong>.<\/p>\n<p>The integrated barometer enables additional pressure measurement functions and allows the instrument to provide gauge or absolute pressure measurement depending on its configuration.<\/p>\n<p>This capability eliminates the need for a separate external barometer in many field calibration applications.<\/p>\n<h2>Electrical Measurement<\/h2>\n<p>The Additel ADT 673 is more than a digital pressure reference.<\/p>\n<p>It also provides integrated electrical measurement functions for process calibration.<\/p>\n<p>The instrument can measure DC voltage up to:<\/p>\n<p><strong>\u00b130.0000 V<\/strong><\/p>\n<p>with a specified accuracy of:<\/p>\n<p><strong>\u00b1(0.01% of reading + 1.5 mV)<\/strong>.<\/p>\n<p>DC current can be measured up to:<\/p>\n<p><strong>\u00b130.0000 mA<\/strong><\/p>\n<p>with a specified accuracy of:<\/p>\n<p><strong>\u00b1(0.01% of reading + 1.5 \u00b5A)<\/strong>.<\/p>\n<p>These capabilities make the ADT 673 particularly suitable for pressure transmitter calibration.<\/p>\n<h2>24 V Loop Power<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> provides built-in:<\/p>\n<p><strong>24 V loop power<\/strong>.<\/p>\n<p>The output is specified as:<\/p>\n<p><strong>24 V \u00b11 V<\/strong><\/p>\n<p>with a maximum current of:<\/p>\n<p><strong>30 mA<\/strong>.<\/p>\n<p>This allows the calibrator to power many common industrial pressure transmitters directly during calibration.<\/p>\n<p>A separate external loop power supply is therefore unnecessary for many field calibration tasks.<\/p>\n<h2>Pressure Transmitter Calibration<\/h2>\n<p>The combination of pressure measurement, current measurement and 24 V loop power makes the <strong>Additel ADT 673<\/strong> an effective pressure transmitter calibrator.<\/p>\n<p>A typical calibration configuration consists of:<\/p>\n<p><strong>Pressure source \u2192 Additel ADT 673 \u2192 Pressure transmitter<\/strong><\/p>\n<p>The internal pressure sensor measures the applied reference pressure.<\/p>\n<p>At the same time, the ADT 673 can measure the transmitter&#8217;s electrical output.<\/p>\n<p>For a conventional industrial transmitter, this is commonly:<\/p>\n<p><strong>4 to 20 mA<\/strong>.<\/p>\n<p>The calibrator can also provide the required 24 V loop power.<\/p>\n<p>This allows the pressure input and electrical transmitter output to be compared using one portable instrument.<\/p>\n<h2>Optional HART Field Communicator<\/h2>\n<p>For intelligent process transmitters, the <strong>Additel ADT 673<\/strong> can be equipped with an optional full HART field communicator.<\/p>\n<p>This enables communication with HART-compatible transmitters directly from the pressure calibrator.<\/p>\n<p>The combination of precise pressure measurement, electrical measurement, loop power and HART communication creates a powerful tool for commissioning, maintenance and calibration of smart pressure transmitters.<\/p>\n<p>Typical HART applications include:<\/p>\n<ul>\n<li>Transmitter configuration<\/li>\n<li>Process variable monitoring<\/li>\n<li>Device diagnostics<\/li>\n<li>Calibration<\/li>\n<li>Field maintenance<\/li>\n<\/ul>\n<h2>Pressure Switch Testing<\/h2>\n<p>The Additel ADT 673 also supports pressure switch testing.<\/p>\n<p>The electrical input can detect:<\/p>\n<p><strong>OPEN\/CLOSED<\/strong><\/p>\n<p>switch states.<\/p>\n<p>Both mechanical switches and NPN\/PNP digital switches are supported.<\/p>\n<p>Pressure can be increased until the switch changes state and then decreased until the switch resets.<\/p>\n<p>This allows determination of:<\/p>\n<ul>\n<li>Switching pressure<\/li>\n<li>Reset pressure<\/li>\n<li>Switching hysteresis<\/li>\n<\/ul>\n<p>The function is particularly useful for commissioning and preventive maintenance.<\/p>\n<h2>3.4-Inch Color Touchscreen<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> uses a modern:<\/p>\n<p><strong>3.4-inch capacitive color touchscreen<\/strong>.<\/p>\n<p>The display is protected by a replaceable tempered-glass screen protector.<\/p>\n<p>The smartphone-like operating concept provides quick access to pressure measurements, electrical functions, configuration settings and stored data.<\/p>\n<p>This modern interface replaces the traditional button-heavy operation found on many conventional pressure calibrators.<\/p>\n<h2>Adjustable Resolution<\/h2>\n<p>The displayed pressure resolution can be configured by the user.<\/p>\n<p>Available settings include:<\/p>\n<p><strong>4 digits<\/strong><\/p>\n<p><strong>5 digits<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>6 digits<\/strong>.<\/p>\n<p>The display update rate can also be adjusted.<\/p>\n<p>The default rate is three readings per second, while settings from:<\/p>\n<p><strong>10 readings per second<\/strong><\/p>\n<p>to:<\/p>\n<p><strong>one reading every 20 seconds<\/strong><\/p>\n<p>are available.<\/p>\n<p>This enables the display behavior to be adapted to dynamic or stable pressure applications.<\/p>\n<h2>Comprehensive Data Logging<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> includes extensive onboard data logging.<\/p>\n<p>The instrument provides:<\/p>\n<p><strong>8 GB internal storage<\/strong><\/p>\n<p>with capacity for:<\/p>\n<p><strong>more than 100 million records<\/strong>.<\/p>\n<p>Both manual and automatic recording modes are available.<\/p>\n<p>Automatic recording intervals can be configured from:<\/p>\n<p><strong>0.1 to 9,999.9 seconds<\/strong>.<\/p>\n<p>This makes the instrument suitable not only for individual calibration points but also for long-term pressure monitoring and process analysis.<\/p>\n<h2>Bluetooth and USB Communication<\/h2>\n<p>Bluetooth and USB Type-C communication are included as standard.<\/p>\n<p>Bluetooth allows the ADT 673 to communicate wirelessly with compatible mobile devices.<\/p>\n<p>USB Type-C provides a convenient wired interface for data transfer and instrument communication.<\/p>\n<p>Depending on the configuration, additional communication options are available.<\/p>\n<h2>Optional Wi-Fi and RS232<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> can be expanded with additional communication interfaces.<\/p>\n<p>Available options include:<\/p>\n<ul>\n<li>Wi-Fi<\/li>\n<li>RS232<\/li>\n<\/ul>\n<p>These interfaces provide additional flexibility for laboratory integration, automated calibration systems and remote data handling.<\/p>\n<h2>Additel Link Mobile App<\/h2>\n<p>The Additel ADT 673 communicates with the <strong>Additel Link mobile app<\/strong>.<\/p>\n<p>This enables users to remotely monitor the pressure calibrator from a compatible mobile device.<\/p>\n<p>Wireless monitoring can be particularly useful when the pressure calibrator is installed at a test point that is difficult to observe directly.<\/p>\n<p>It also provides a convenient modern interface for field technicians.<\/p>\n<h2>IP67 Protection<\/h2>\n<p>The <strong>Additel ADT 673<\/strong> is rated:<\/p>\n<p><strong>IP67<\/strong>.<\/p>\n<p>This robust protection level makes the calibrator suitable for demanding field and laboratory environments.<\/p>\n<p>The enclosure is manufactured from <strong>304 stainless steel<\/strong>, while the wetted parts use <strong>316 stainless steel<\/strong>, with exact wetted materials dependent on the selected pressure range.<\/p>\n<p>The instrument is also specified for vibration and shock resistance, supporting professional field use.<\/p>\n<h2>Rechargeable Battery<\/h2>\n<p>The ADT 673 uses a rechargeable lithium-ion battery.<\/p>\n<p>Typical battery operating time is approximately:<\/p>\n<p><strong>16 hours<\/strong>.<\/p>\n<p>Typical charging time is
