where should the oil pressure gauge be
It is usually behind the engine, on the cylinder block and next to the oil filter element seat. There is a plug with a wire on it, which is located on the oil passage in front of the oil filter element. The oil pressure indicator is installed on the instrument panel, and the oil pressure sensor is installed on the engine main oil passage or oil primary filter, which are connected through wires; Common oil pressure gauges include bimetallic oil pressure gauge and bimetallic oil pressure sensor, electromagnetic oil pressure gauge and resistive oil pressure sensor. Bimetallic oil pressure gauge is widely used.
The electronic oil pressure sensor is composed of thick film pressure sensor chip, signal processing circuit, shell, fixed circuit board device and two leads. The signal processing circuit is composed of power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filter circuit and alarm circuit. Thick film pressure sensor is a new type of strain pressure sensor appeared in the 1980s. It is developed by using the piezoresistive effect of thick film resistance printed and sintered on ceramic elastomer. Four thick film resistors are directly printed and sintered on the ceramic elastic diaphragm, and connected into a Wheatstone bridge through the conduction belt. When the measured liquid level pressure acts on the ceramic elastomer, the elastic diaphragm will produce deflection deformation. At the same time, the thick film resistance printed and burned on the elastic diaphragm will also produce the same amount of strain, of which two thick film resistors will be strained under pressure and the resistance value will decrease; For the other two tensile strains, the resistance increases. In this way, the measured pressure value is converted into the bridge output signal, and the signal size is directly proportional to the pressure.
