Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

Analog/BCD Output type Amplifier with Round Digital(Pressure/Load) Display
VPC series Sensor separate type Analog/BCD output


* Actual products may differ from photo depending on specifications.


Use in combination with pressure sensors or load cells.

  • 5 analog outputs and 4 BCD outputs can be selected and used together.
  • VPC and sensor are calibrated as a pair, including the sensor cable length, and constitute a high-accuracy digital pressure meter.
  • Fast response analog output without microcomputer is available that is suitable to fluid pressure measurement.
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 VPC 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.
