MID-WEST Models 700, 710, 715 差压变送器
 
Mid-West Instrument Model 700 Wet/Wet Differential Pressure Transmitter utilizes a piezoresistive differential pressuresensor 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 outputgenerated by the piezoresistive bridge sensor is amplified into a useable voltage or 4-20 mA output as specifiedby customer. 1 Year Limited Warranty
