Rotronic BF220 Process Pressure Transmitter & Measurement Instrument
Rotronic BF220 Transmitter – Process Pressure Measurement
Rotronic BF220 process pressure measurement transmitter provides reliable measurement of the pressure of neutral gases and nitrogen in piping and closed containers within a compact and robust construction.
The pressure of the medium being measured acts on a pressure cell, which converts the pressure into an electronic signal.
The Rotronic BF220 transmitter is ideal for the measurement of absolute pressure in applications with fast temperature changes and in compressed air, HVAC and pneumatic systems.

Measurement Of Process Pressure & Field Of Application
Pressure transmitters measure the pressure of neutral gases and nitrogen in piping and closed containers. During this process, the pressure of the medium being measured acts as a pressure cell and converts it to an electronic signal.
The Rotronic BF220 is ideal for the measurement of absolute pressure in applications with fast temperature changes and in compressed air, HVAC and pneumatic systems.
