DPT 100 Differential Pressure Transmitter for Process Industry accuracy according to IEC 60770: 0.1 % FSO The differential pressure transmitter DPT 100 has been especially designed for fast test processes in leakage and flow measurement, where a fast response time and high sampling rate are necessary. from 10 mbar up to 20 bar Static pressure The compact design of the DPT 100 facilitates the usage in standardised applications. For instance, the installation in 19" racks. Output signal The DPT 100 with optionally 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 – the data will transfer in binary form. 2-wire: 4 ... 20 mA RS485 with Modbus RTU protocol Special characteristics ► compact design fast response time aluminium die cast case zero adjustment via button Preferred areas of use are Test engineering / leak testing Machine and plant engineering several process connections Environmental technology Energy production BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
