Electronic pressure transmitters and regulators
Electronic pressure transmitters and regulators for gases and liquids are of well proven technical design, full bore. The instruments include piezo-resistive pressure sensors which allow pressure measurement and control in expansion or relief mode: - the lowest range 2 ... 100 mbar absolute, relative or differential - the highest range 8 . .. 400 bar absolute / relative or 0.3 ... 15 bar differential. The devices are available for laboratory applications or for industrial processes (depending on models). They can be equipped with an interface with the CANopen®, DeviceNetTM, Profibus-DP®, PROFINET, EtherCAT®, Modbus or FLOW-BUS protocol. Pressure range up to 400 bar - Metal seal and/or manifold version available.
