SATRON VDt is used for 0-0,1kPa...0-15 MPa ranges. The transmitter communicates in a 2-wire system. In pressure measuring applications SATRON VDt transmitters are used for measuring differential pressure and vacuum pressure. SATRON VDt transmitter is equipped with an SOS (Silicon On Sapphire) or piezoresistive sensing elemente. The rangeability is 25:1. The transmitter communicates digitally using the HART® protocol.
