Differential Pressure Transmitter

Dwyer Instruments offers Series 645 wet/wet differential pressure transmitters. They deliver ?0.25% of full-span accuracy and are for use with compatible liquids and gases. These controls feature wetted parts including 17-4 PH and 300 series stainless steel, Viton, and silicone rubber O-rings and seals. The transmitters employ a 2-wire circuit design with a fast response capacitance sensor to produce a 4-20 mA output signal. Zero and span controls are included for field calibration if needed. Series 645 is available in 14 factory calibrated ranges.
