Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

Amplifier with Square type (Pressure/Load) Display for Press, Injection and Bending
VPXM series


* Actual products may differ from photo depending on specifications.


Use in combination with pressure sensors or load cells.

  • Compact and high-efficiency amplifier with digital display for Go/No-Go judgment of press work.
  • Specialized in press, press fitting and caulking with the dedicated measurement timing chart.
  • Abundant options to support OEM production.
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 VPXM 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.
  • ■2S type
    Most common type that outputs judgment with the maximum value after the measurement period is finished.
  • ■2SA1 type
    Suitable for processes of fast cycle time where judgment output is required as soon as the measurement is finished.
  • ■2SA2 type
    Suitable for processes with longer measurement period (time) where judgment output is required in real-time during measurement.

2.Analog output
*Analog output and BCD output can be used together.
- - Output type Response frequency Power consumption
  Blank None - -
  D Display only
  A1 1mV/digit
(±1999mV max.)
1.2kHz This value has been calculated as response frequency (= 1/2T (Hz)) based on the measured step response (0–100%) and rise time (T) with the sensor bridge resistance of 350Ω. Response frequency is determined by the sensor to be used. Consult with us when focusing on response. 10kΩ or more
