Description
The surge transmitter (SDV-Exd pressure transmitter with RS485 interface) is used to measure absolute pressure or gauge pressure of air behind the compressor.
The surge transmitter makes it possible to determine compressor gas-dynamic stability losses by the value of relative pulsations of air pressure behind the compressor or by the rate of air pressure drop behind the compressor.
The surge transmitter is manufactured in Non-explosion-proof option (SDV) and in Explosion-proof versions (SDV-Exd).
Pressure transmitters are supplied with valve blocks.
