design<\/li>\n<\/ul>\n<h2>Designed Specifically for Barometric Pressure Calibration<\/h2>\n<p>The <strong>Additel ADT 761A-BP<\/strong> differs significantly from the other models in the ADT761A family.<\/p>\n<p>It was specifically developed for:<\/p>\n<p><strong>barometer sensor calibration<\/strong><\/p>\n<p>Rather than generating gauge or differential pressure, the BP version directly generates and measures absolute pressure over a range of:<\/p>\n<p><strong>100 to 1,200 hPa<\/strong><\/p>\n<p>This makes the instrument especially useful for calibration applications where atmospheric pressure must be simulated accurately and reproducibly.<\/p>\n<p>Typical devices under test include:<\/p>\n<ul>\n<li>Digital barometers<\/li>\n<li>Analog barometers<\/li>\n<li>Barometric pressure sensors<\/li>\n<li>Absolute pressure sensors<\/li>\n<li>Meteorological pressure instruments<\/li>\n<li>Environmental monitoring systems<\/li>\n<li>Weather station pressure sensors<\/li>\n<li>Atmospheric pressure data loggers<\/li>\n<\/ul>\n<h2>Absolute Pressure from 100 to 1,200 hPa<\/h2>\n<p>The ADT 761A-BP covers:<\/p>\n<p><strong>100 hPa to 1,200 hPa absolute<\/strong><\/p>\n<p>The lower end of this range represents a pressure substantially below typical atmospheric pressure at ground level.<\/p>\n<p>The upper end of 1,200 hPa extends above normal sea-level atmospheric pressure.<\/p>\n<p>This allows a very wide range of atmospheric pressure conditions to be generated using a single automatic calibration system.<\/p>\n<p>The pressure range corresponds approximately to:<\/p>\n<p><strong>10 to 120 kPa absolute<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>0.1 to 1.2 bar absolute<\/strong><\/p>\n<p>This wide range makes the ADT 761A-BP suitable not only for conventional barometers but also for absolute pressure sensors used over extended atmospheric pressure ranges.<\/p>\n<h2>Pressure Accuracy of 0.01 % FS<\/h2>\n<p>Additel specifies the accuracy of the <strong>ADT 761A-BP<\/strong> as:<\/p>\n<p><strong>0.01 % FS<\/strong><\/p>\n<p>FS refers to the span of the pressure range.<\/p>\n<p>For the BP configuration, the pressure span is:<\/p>\n<p><strong>1,200 hPa &#8211; 100 hPa = 1,100 hPa<\/strong><\/p>\n<p>This means that 0.01 % of the 1,100 hPa span corresponds to:<\/p>\n<p><strong>0.11 hPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>11 Pa<\/strong><\/p>\n<p>This illustrates the high level of measurement performance available for barometric pressure calibration.<\/p>\n<p>The manufacturer&#8217;s accuracy specification is a one-year accuracy including one-year stability.<\/p>\n<h2>Excellent 0.02 hPa Control Stability<\/h2>\n<p>In addition to measurement accuracy, stable pressure generation is essential when calibrating a barometer.<\/p>\n<p>Additel specifies the pressure control stability of the ADT 761A-BP as:<\/p>\n<p><strong>0.02 hPa<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>2 Pa<\/strong><\/p>\n<p>Stable automatic pressure control allows the device under test to settle at each calibration point before its indication is compared with the ADT 761A-BP reference pressure.<\/p>\n<p>This is particularly valuable during automated multipoint calibration procedures.<\/p>\n<h2>Fully Automatic Pressure Generation<\/h2>\n<p>The <strong>Additel ADT 761A-BP<\/strong> contains an integrated electric pump.<\/p>\n<p>The instrument can therefore automatically generate the required absolute pressure without a separate external pressure generator for normal operation within its specified range.<\/p>\n<p>The operator enters the desired pressure setpoint and the calibrator automatically:<\/p>\n<ol start=\"1\">\n<li>Generates the required pressure<\/li>\n<li>Approaches the selected pressure<\/li>\n<li>Regulates the pressure<\/li>\n<li>Stabilizes the setpoint<\/li>\n<li>Measures the reference pressure<\/li>\n<\/ol>\n<p>This significantly simplifies repetitive barometer calibration.<\/p>\n<h2>Automatic Multipoint Barometer Calibration<\/h2>\n<p>A barometer should normally be evaluated at multiple pressure points rather than only at the current atmospheric pressure.<\/p>\n<p>The automatic pressure generation of the ADT 761A-BP makes it possible to generate a sequence of defined absolute pressures.<\/p>\n<p>For example, a calibration procedure can include increasing and decreasing pressure points throughout the required operating range.<\/p>\n<p>This allows characteristics such as:<\/p>\n<ul>\n<li>Indication error<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Pressure-dependent deviation<\/li>\n<\/ul>\n<p>to be evaluated.<\/p>\n<p>Automatic pressure control significantly reduces the manual work required for this type of calibration.<\/p>\n<h2>One Dedicated Internal Pressure Module<\/h2>\n<p>An important difference between the ADT 761A-BP and most other ADT761A configurations is the internal pressure module architecture.<\/p>\n<p>The <strong>ADT 761A-BP uses one internal pressure module<\/strong>.<\/p>\n<p>This internal module is dedicated to the barometric range:<\/p>\n<p><strong>100 to 1,200 hPa absolute<\/strong><\/p>\n<p>The internal module is not specified as removable.<\/p>\n<p>This differs from the LLP, D, 500, 1K and 1.5K versions, which can accommodate two removable internal pressure modules.<\/p>\n<p>The BP version is therefore optimized as a dedicated barometric calibration system rather than a multi-range gauge pressure calibrator.<\/p>\n<h2>Two External Pressure Module Connections<\/h2>\n<p>Although the BP version uses one dedicated internal pressure module, the ADT761A platform provides connections for:<\/p>\n<p><strong>two external pressure modules<\/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 its dedicated internal barometric pressure range.<\/p>\n<p>The external modules do not change the automatic pressure generation range of the internal BP system.<\/p>\n<h2>Ideal for Meteorological Instruments<\/h2>\n<p>Atmospheric pressure is one of the fundamental measurement parameters in meteorology.<\/p>\n<p>Barometric pressure measurements are used in:<\/p>\n<ul>\n<li>Weather stations<\/li>\n<li>Meteorological networks<\/li>\n<li>Environmental monitoring<\/li>\n<li>Climate research<\/li>\n<li>Atmospheric measurements<\/li>\n<li>Industrial environmental monitoring<\/li>\n<\/ul>\n<p>The <strong>Additel ADT 761A-BP<\/strong> provides a convenient method for applying known absolute pressures to barometric instruments under controlled conditions.<\/p>\n<h2>Applications in Aviation and Altitude Measurement<\/h2>\n<p>Barometric pressure is also fundamental to altitude determination.<\/p>\n<p>Aircraft altimeters and many altitude-related instruments derive altitude information from atmospheric pressure.<\/p>\n<p>The wide absolute pressure range of the ADT 761A-BP makes the instrument interesting for applications involving pressure sensors used in altitude-related measurement systems.<\/p>\n<p>The exact suitability for a specific aviation instrument should always be evaluated against the applicable technical and regulatory requirements.<\/p>\n<h2>Electrical Process Functions<\/h2>\n<p>The ADT761A platform also provides integrated electrical measurement and source functions.<\/p>\n<p>These functions include:<\/p>\n<ul>\n<li>mA measurement<\/li>\n<li>Voltage measurement<\/li>\n<li>mA sourcing<\/li>\n<li>24 V loop power<\/li>\n<\/ul>\n<p>This can be useful when the barometric or absolute pressure sensor being calibrated provides an electrical output signal.<\/p>\n<p>For example, the ADT 761A-BP can generate the required absolute pressure while the electrical output of a connected transmitter is evaluated.<\/p>\n<h2>4\u201320 mA Pressure Transmitters<\/h2>\n<p>Many industrial absolute pressure transmitters use a:<\/p>\n<p><strong>4\u201320 mA<\/strong><\/p>\n<p>output signal.<\/p>\n<p>With its integrated electrical functionality, the ADT 761A-BP can support calibration workflows involving both the applied pressure and electrical transmitter output.<\/p>\n<p>The integrated 24 V loop power can also supply compatible two-wire process transmitters.<\/p>\n<p>This reduces the number of separate instruments required for many calibration setups.<\/p>\n<h2>HART Communication<\/h2>\n<p>The <strong>Additel ADT 761A-BP<\/strong> supports:<\/p>\n<p><strong>HART communication<\/strong><\/p>\n<p>for compatible intelligent field instruments.<\/p>\n<p>HART communication can support:<\/p>\n<ul>\n<li>Device identification<\/li>\n<li>Reading digital measurement values<\/li>\n<li>Device configuration<\/li>\n<li>Diagnostics<\/li>\n<li>Calibration workflows<\/li>\n<\/ul>\n<p>This makes the ADT 761A-BP suitable for modern smart absolute pressure transmitters as well as conventional barometric sensors.<\/p>\n<h2>PROFIBUS PA Communication<\/h2>\n<p>The ADT761A platform also supports:<\/p>\n<p><strong>PROFIBUS PA<\/strong><\/p>\n<p>communication.<\/p>\n<p>This provides additional flexibility when working with compatible digital process instrumentation.<\/p>\n<p>Together with automatic absolute pressure generation and electrical measurement functions, this makes the ADT 761A-BP a versatile calibration platform.<\/p>\n<h2>Task Documentation<\/h2>\n<p>The <strong>Additel ADT 761A-BP<\/strong> supports task documentation.<\/p>\n<p>Recurring calibration procedures can therefore be organized as defined workflows.<\/p>\n<p>This is particularly useful when several barometers of the same type must be calibrated using an identical sequence of pressure points.<\/p>\n<p>Standardized calibration procedures improve consistency and reduce repetitive manual operation.<\/p>\n<h2>Integrated Data Logging<\/h2>\n<p>The ADT761A platform provides integrated:<\/p>\n<p><strong>Data Logging<\/strong><\/p>\n<p>Additel specifies storage for up to:<\/p>\n<p><strong>1,000,000 readings<\/strong><\/p>\n<p>Measurement data can therefore be recorded directly by the calibration system.<\/p>\n<p>This can be useful for:<\/p>\n<ul>\n<li>Calibration documentation<\/li>\n<li>Pressure stability testing<\/li>\n<li>Long-term measurements<\/li>\n<li>Environmental monitoring<\/li>\n<li>Sensor evaluation<\/li>\n<li>Troubleshooting<\/li>\n<\/ul>\n<h2>Modern Communication Interfaces<\/h2>\n<p>The <strong>Additel ADT 761A-BP<\/strong> provides modern communication interfaces including:<\/p>\n<ul>\n<li>Wi-Fi<\/li>\n<li>Bluetooth<\/li>\n<li>USB<\/li>\n<li>LAN \/ Ethernet<\/li>\n<\/ul>\n<p>These interfaces facilitate integration into digital calibration environments and communication with computers and compatible peripheral equipment.<\/p>\n<h2>Color Touchscreen and Keypad Operation<\/h2>\n<p>The ADT761A features a:<\/p>\n<p><strong>7-inch TFT color touchscreen<\/strong><\/p>\n<p>with a resolution of:<\/p>\n<p><strong>800 \u00d7 480 pixels<\/strong><\/p>\n<p>The instrument can be operated using the touchscreen and keypad.<\/p>\n<p>Pressure setpoints, measurement functions, calibration tasks and instrument settings can be accessed directly through the user interface.<\/p>\n<h2>Rechargeable Battery<\/h2>\n<p>The ADT761A uses a rechargeable Li-ion battery.<\/p>\n<p>Typical battery operation is approximately:<\/p>\n<p><strong>8 hours<\/strong><\/p>\n<p>and charging takes less than approximately:<\/p>\n<p><strong>4 hours<\/strong><\/p>\n<p>This makes the ADT 761A-BP suitable not only for stationary laboratory use but also for mobile calibration applications.<\/p>\n<h2>Compact Portable Design<\/h2>\n<p>The ADT761A platform measures approximately:<\/p>\n<p><strong>299 \u00d7 193 \u00d7 192 mm<\/strong><\/p>\n<p>and weighs less than approximately:<\/p>\n<p><strong>7.95 kg<\/strong><\/p>\n<p>The combination of automatic pressure generation, precision measurement, electrical functions and rechargeable battery operation provides a portable solution for both laboratory and field calibration.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> Additel ADT 761A-BP<\/p>\n<p><strong>Device type:<\/strong> Automatic Barometric Pressure
