Profile: Ninghai Sendo International Trading Co., Ltd offers pressure transducers, automotive pressure sensors and oil pressure sensors. Our piezoresistive pressure sensor element is used in industrial process control, liquid pressure system & switch, level measure, gas & liquid pressure measure, pressure inspection meter, pressure calibrator, cooling equipment & air conditioner and in aviation & navigation inspection systems. Our automotive oil pressure sensor is a device that measures the pressure at which the oil pump is pumping engine oil. Most oil pumps operates in the 20 to 40 pounds per square inch range. If the oil pressure drops below this level, permanent engine damage can occur. The oil pressure sensor on some cars sends signals to an oil pressure gauge on the dashboard electrically. The voltage level of this signal will pertain to a given level of pressure. Our sensors adopt diffused silicon sensor chip, with smart figure, easy installment and the special valve pin design for lead pressure port.
