Piping and hoses, for example steel bottles, compressors, breathing devices, oxyacetylene gas and inert-gas arc welding devices and burners Fittings, flanges, valves, screwed connections, soldered and welded connections of pressure gas systems and lines Suitable for compressed air, refrigerant, acetylene, butane, natural gas, carbon dioxide, gaseous oxygen, propane, town gas, nitrogen, hydrogen and, ammonia Advantages and benefits Acts non-corrosive Allows direct visual inspection of the leakage point through bubble formation Tested by the DVGW in accordance with DIN EN 14291 Suitable for spraying overhead

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. The compact design of the DPT 100 facilitates the use in standardised applications, e. g., and the installation in 19“ Rack. 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. Features: — differential pressure from 10 mbar up to 20 bar — static pressure max. 400 bar — accuracy: 0.1 % FSO — output signal 4 ... 20mA / 2-wire — aluminium housing, die casting Optional Features: — output signal RS485 with Modbus RTU protocol — several process connections
