DCT 531 Industrial Pressure Transmitter with RS485 Modbus RTU Stainless Steel Sensor accuracy according to IEC 60770: 0.25 % FSO Nominal pressure from 0 ... 100 mbar up to 0 ... 400 bar output signal RS485 with Modbus RTU protocol Due to the usage of high quality materials and components, the DCT 531 is suitable for almost every industrial application, if the medium is compatible with stainless steel 316L. pressure value perfect thermal behaviour excellent long term stability reset function The modular concept of the device allows customized mechanical connections, so it is easy to adapt the pressure transmitter to different conditions on-site. pressure port G 1/2" flush up to max. 40 bar Plant and machine engineering pressure sensor welded The DCT 531 with RS485 interface uses the communication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master slave architecture with which up to 247 slaves can be questioned by a master. customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein Energy industry www.bdsensors.de info@
