Absolute pressure transmitter for measuring absolute pressures in closed systems

Special features

    • High level of accuracy and long-term stability
    • Little zero point drift or hysteresis; largely independent of temperature
    • Reduction can be performed to adjust to the altitude of the place of installation
    • Available for a variety of measuring ranges, output signals and supply voltages
    • Available with display (optional)
    • Can be calibrated
The AD 1000 absolute pressure transmitter is designed to display atmospheric pressure (BA 1000) and absolute pressure. At the heart of the unit is an evacuated measurement cell made from an elastic copper material. The deflection of the measurement cell due to absolute pressure is measured inductively without making contact. The transmitter emits an electrical output signal proportional to the absolute pressure. The device can be powered using a 24 VDC power supply or a variety of AC voltages. The pressure port is led through in the AD 1000 making it suitable for measuring absolute pressures in closed systems.

  • Available with an factory calibration certificate or calibration certificate according to DKD-R 6-1 (optional).
  • Also available with LCD (optional).
