DCT 531i

BD Sensors DCT 531i Stainless Steel Digital Pressure Transmitter with RS485 Modbus RTU & Welded Stainless Steel Sensor, Pressure Range from 0 … 100 mbar up to 0 … 400 bar & Accuracy of 0.1% FSO

SKU: DCT 531i Category:

The DCT 531i is characterized by very good accuracy and excellent temperature behaviour and is therefore ideally suited for applications where precise pressure measurement is necessary (e.g. test benches, leakage tests, etc.). Thanks to the 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. Different mechanical and electrical connections are available so that the DCT 531i can be used in various applications without any problems.
