BF2 Pressure Transmitter
Features
- Compact and robust construction
- Piezo-resistive steel sensor
- Zero and range adjustable with internal potentiometer
- IP protection IP65
Pressure transmitters measure the pressure of neutral gases and nitrogen in piping and closed containers. The pressure of the medium being measured acts on a pressure cell, which converts the pressure into an electronic signal.
Field of Application
The process pressure transmitters are ideal for measurement of absolute pressure in applications with fast temperature changes and in compressed air, HVAC and pneumatic systems.
