Honeywell HSDP-W Series Liquid Differential Pressure Transmitters are mainly used for the measurement of liquid pressure. The sensitive element of the liquid differential pressure transmitters is a solid piezoresistive sensitive chip, and the part in contact the measured liquid is the corrugated diaphragm on both sides of the transmitters, and the space between the sensitive chip and the corrugated diaphragm is filled with silicone oil. The measured differential pressure acts on the corrugated diaphragm and is transmitted to the sensitive chip through silicone oil. Using the piezoresistive effect of semiconductor silicon materials, the conversion of differential pressure and electrical signals is realized. Since the output signal of the Wheatstone bridge on the sensitive chip has a good linear relationship with the differential pressure, accurate measurement of the measured differential pressure can be realized.
