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.
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.
