SATRON VDU differential pressure transmitter is 2-W transmitter and is used from 0-1.4 kPa to 0-3 MPa ranges. In pressure measuring applications SATRON VDU diff.pressure transmitters are used for measuring the pressure of clean, sedimenting, crystallizing and sticking materials.The transmitter's sensor is piezoresistive. The rangeability is 25:1. The transmitter communicates digitally using the HART® protocol.
