* Actual products may differ from photo depending on specifications.


Use in combination with pressure sensors or load cells.

  • Equalizing valve not required for differential pressure display.
  • Added and subtracted values can be read directly.
  • 5 analog outputs and 4 BCD outputs can be selected and used together.
  • Display can be changed between "A, B, A+B" and "A, B, A-B" according to the selective specification.
Can be combined with sensors Can be combined with all models of pressure sensors and load cells.
Sensor specifications Refer to the pages of pressure sensors and load cells.
Calibration of amplifier and sensor VPS amplifiers and pressure sensors or load cells have been calibrated as a pair.
Amplifiers and sensors have been calibrated as a pair under the same serial number.
