VALCOM CO.,LTD.

 

Minute Differential Pressure Transmitter
VDP4 series
2.5kPa–105kPa

  • Enables differential pressure measurement from 1.25 kPa (up to 105 kPa)
  • Compact and easy-to-mount.
Measured medium Dedicated to inert gases (noncorrosive gases) such as air, nitrogen, argon, etc.
Pressure Type Positive, compound and negative pressures can be measured.
Measured Range Can be specified within the range of 2.5 kPa to 105 kPa (Calibration: 1.25 to 105kPa) of rated capacity.
Specify more than 50% of rated capacity as the calibration range.
Output type 4–20mA (2 wire system)
