IMP Industrial Pressure Sensor

Select Options ⇒ Request Price
PDF

IMP series industrial pressure sensor
The industrial pressure transmitter, IMP, has a piezoresistive ceramic pressure sensor giving it excellent media compatibility. The housing is made from stainless steel with a choice of internal O ring seals to select to ensure the product is suitable for a wide range of applications. Every device is temperature compensated and calibrated and supplied with a traceable serial number and calibration certificate. The electronics incorporate a microprocessor based amplifier, this means there are no adjusting pots and therefore the electronics are very stable, especially in high vibration / shock applications.

  • Thick film ceramic sensor
  • Accuracy: <±0.25% FS BFSL (0.1% optional)
  • Pressure ranges from 0.5 to 700 bar
  • Gauge, Sealed Gauge or Absolute reference
  • Variety of Outputs including mV, Volts and mA
