The DCT 531i is characterized by very good accuracy and excellent temperature behaviour and is ideally suited for precise pressure measurement (e.g. test benches, leakage tests, etc.). With integrated RS485 interface (based on the MODBUS RTU protocol), reliable and robust data transmission is available, which also works without problems over longer distances. Since the DCT 531i works directly with a master e.g. is coupled to a SPS, conversion losses of an analogue input card are avoided.
