Series 700 Wet/Wet


Competitively priced, compact wet/wet differential pressure transmitter. For use on liquid or gas media compatible with material of construction.

Mid-West Instrument Model 700 Wet/Wet Differential Pressure Transmitter utilizes a piezoresistive differential pressure sensor sensing element with stainless steel isolated diaphragm. Silicon oil is filled in between die and two diaphragms. The measured differential pressure is transmitted onto the die through the diaphragm and silicon oil. The signal output generated by the piezoresistive bridge sensor is amplified into a useable voltage or 4-20 mA output as specified by customer. 1 Year Limited Warranty
