oil pressure sensor price
Oil pressure sensor price is from USD6.9-USD19.9,Nanjing Hemu International Trade Co.Led, we have different helix and two color for you to choose.You can just let we know what kind of oil pressure sensor you need,we will send our best price.Oil pressure is one of the important parameters of a car engine. When the oil pressure is too low, it may damage the engine, so an oil pressure gauge needs to be installed on the car to monitor the oil pressure during engine operation. In the introduction of the work of the oil pressure indicator principle and based on the traditional oil pressure sensor,choose the best one,The electronic oil pressure sensor is composed of a thick film pressure sensor chip, a signal processing circuit, a shell, a fixed circuit board device and two leads (signal line and alarm line). The signal processing circuit consists of power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filter circuit and alarm circuit.
The solution to the high oil pressure of the engine is:
1.Adjust the clearance between the journal and the bearing of the pressure lubrication part;
2.Clean the lubricating oil pipe, oil passage, and maintain the filter;
3.Select the appropriate oil grade;
4.Replace the appropriate
5.Check and adjust the pressure limiting valve on the oil pump test bench to make the oil pressure meet the specified requirements.
The structure of the oil pressure sensor:
The oil pressure sensor is mainly composed of pressure tap, transmission circuit and electrical output interface. The basic structure of the voltage take-off is to sense the pressure change through the strip resistance. At the same time, the resistance change is amplified into the pressure difference through the Wheatstone bridge structure, and then transmitted to the transmission circuit for filtering, amplification and other processing. In the process of oil pressure detection, its temperature change is inevitable. Usually, a separate thermistor is made outside the four resistance bars of the Wheatstone bridge to synchronously detect the temperature change in the area where the sensitive resistor is located and provide the temperature value for subsequent temperature drift correction. At the same time, in order to prevent the impact of oil pressure overshoot, some products have an inverted funnel inlet at the front end of the pressure tap, which can obviously avoid and reduce the impact of oil pressure overshoot
