Product Description

Gauge Pressure 4-20mA Pressure transmitter

Model: WP401A


This Gauge Pressure 4-20mA Pressure transmitter can be used to measure PRESSURE in:

  • Petroleum and chemical industry,
  • Gas Bolier, Gas burner
  • Electric power, water supply,
  • Oil & Gas and other automatic control industries


1. WP401A Gauge Pressure 4-20mA Pressure transmitter adopt advanced imported sensor component, which is combined with the solid state integrated technological and isolate diaphragm technology.

2. The gauge pressure swtich/transmitter is designed to work well under various conditions.

3. The temperature compensation resistance makes on the ceramic base, which is the excellent technology of the pressure transmitters.

4. Various output signal 4-20mA (2-wire), strong anti-jamming, it is suitable for long distance transmission.
