Automated Pressure Calibrator


Manufacturer: Additel

Automatic pressure calibrators series ADT761A consist of a pressure calibrator and an integrated electrical pump. ADT761A calibrators are designed for the automatic calibration of pressure transmitters, pressure switches, gauges, etc. External hand pumps or similar are not necessary when using the ADT761A.

Various available models cover the range ±75 mbar to -0.9…70 bar (see “additional information” for details). Each unit can be equipped with 2 internal pressure modules (high pressure/low pressure). In addition, external pressure modules can be connected for measurement in extended ranges.

Pressure calibrators series ADT761A are documenting calibrators and include a data logger function as well as a HART communicator. Communication to transmitters with Profibus PA signal is also possible.

The module for measuring current and voltage as well as recording switch states is integrated.



Additional information

  • 6 different basic units available: Model 761A-LLP (differential pressure, relative pressure): ±75 mbar Model 761A-D (differential pressure, relative pressure): -0.95...2.5 bar Model 761A-500 (relative pressure, absolute pressure): -0.9...35 bar Model 761A-1K (relative pressure, absolute pressure): -0.9...70 bar Model 761A-APXR (relative pressure, absolute pressure): depending on the sensor type APXR is ordered Model 761A-BP (absolute pressure): 100...1200 hPa
  • Each model can be equipped with a second pressure module; calibrator can cover high-pressure and low-pressure range
  • The possibility of connecting external pressure modules extends the range of application (measurement only)
  • Operation via 7" colour touch screen
  • Communication option via USB, WiFi, Bluetooth and Ethernet
