PU21 / PI21 - Pressure transmitter, measuring range: 0...100 bar, for relative pressure
The PU21 and PI21 pressure transmitters are used to measure relative pressures in the range from 0...1 bar to 0...100 bar.
The PU21 and PI21 pressure transmitters are suitable for precise measurement of relative pressures in the range from 0...1 bar to 0...100 bar. The wetted parts are made of ceramic (Al2O3), Viton and stainless steel. The PU21 transmitter is designed in three-wire technology and provides an output signal of 0...10 V. The PI21 transmitter, on the other hand, uses two-wire technology and provides an output signal of 4...20 mA. The electrical connection for both versions is made via an angled connector according to DIN 43650. The pressure connection has a G 1/2" thread.
