ME 771 Piezoresistive Pressure Sensor Flush Membrane with signal conditioning

Experience precision and stability with ME 771 Pressure Sensors. These sensors employ a ceramic base body with a flush diaphragm, operating through the piezoresistive principle and a Wheatstone bridge. Signal conditioning electronics generate a 4…20 mA current loop output. Electronically calibrated for pressure and temperature, the onboard ASIC ensures accurate readings in bar (ME771) or psi (MEP771). Enjoy offset and span correction for temperature changes and constant ageing detection. The ME 771 family meets EMC requirements, offers sensor traceability and allows custom calibration. With excellent chemical immunity, these sensors are ideal for handling aggressive media.

ME 771 Ceramic Pressure Transducer Product Parameters

  • Pressure Ranges: Nominal pressure ranges from 0.5 to 600 bar, and corresponding psi ranges from 5 to 8500, with overload and burst pressure specifications.
  • Output Signal: ME770/MEP770 offers a ratiometric output of 0.5…4.5 [V], ME771/MEP771 uses a current loop with 4…20 [mA], and ME772/MEP772 provides a non-ratiometric output of 0…10 [V].
  • Accuracy: Includes calibration with high accuracy, standard accuracy, and without thermal compensation, with the highest accuracy at 25°C (±1.0-1.5% FS) and the maximum deviation of ± 0.08 %FS/K.
  • Electrical Connections: Supply voltage ranges from 4.5 to 5.5 VDC for ME770/MEP770, 9 to 35 VDC for ME771/MEP771, and 12 to 35 VDC for ME772/MEP772.
