Sino-Inst products

Piezoresistive Differential Pressure Transmitter uses integrated all-welded differential pressure measuring elements. Silicone oil is filled between the chip and the two corrugated diaphragms. This product utilizes the piezoresistive effect of semiconductor silicon materials. To achieve the conversion of differential pressure and electrical signals. The signal output from the Wheatstone bridge on the sensitive chip has a good linear relationship with the differential pressure. Therefore, accurate measurement of the measured differential pressure can be achieved. It is suitable for differential pressure measurement of various gases and liquids in petroleum, chemical.
