? High temperature and low temperature resistance ? Resistant to transmission oil and high reliability ? High precision large range ? Good corrosion resistance ? Low coefficient of thermal expansion.
The liquid level sensor adopts a special structural design, which can ensure the sealing problem after the sensor is installed in the engine. The double sealing ring design is adopted outside the sensor, which can effectively ensure that there is no oil leakage. In addition, the design of this product adopts imported resistance wire, which can ensure the accuracy and reliability of the product.
The sensor uses the current thermal effect of the resistance wire. In different liquid levels and temperatures, the product causes different resistance changes in the energized △ T, and then the product has different partial voltage in the whole circuit. Finally, it outputs different potential difference △ U. the ECU calculates the other value from two of them according to the mapping matrix diagram of liquid level, temperature and potential difference.
The oil level sensor is a sensor specially used to detect the engine oil level. The sensor is installed in the engine oil pan to detect the engine oil level and feed back to the ECU. The sensor is used to measure the liquid level position and height of automobile engine under static (starting instant) conditions.
