overview：

The sensitive element of PDT10SR-230 differential pressure transmitter is a solid piezoresistive chip, silicon oil is filled between chip and two corrugated diaphragms. When the measured differential pressure is added on two corrugated diaphragms, the pressure could be transferred to sensitive chip through silicon oil, sensitive chip connects with amplifier circuit through wires. This product uses the piezoresistive effect of semiconductor silicon material to realize the conversion between differential pressure and electrical signals. The output signal from Weston Bridge on the sensitive chip has a good linear relationship with differential pressure, so the differential pressure could be measured precisely. The product is suitable for differential pressure measurement of various gases and liquids in pipelines such as Petroleum, Chemical, Power station and Hydrology, etc.
