What factors affect Fuel Oil Pressure Sensor?

          There are many factors that affect the stability of Fuel Oil Pressure Sensor. Generally, there is the structure of the pressure sensor. The design of the elastic components, housing, diaphragm, upper indenter and lower pressure pad of the sensor must ensure that the structure can not Relevant performance fluctuations should occur, or the performance fluctuations should be small, so when designing a pressure sensor, try to make the strain zone stress single and the stress uniform.

          The patch part is flat. Generally speaking, it is necessary to ensure the ability to resist eccentric load and lateral load on the structure, so that the installation force will be far from the strain zone, and the displacement of the load support point can be avoided during measurement. The pressure sensor is an assembly manufacturing product, so in order to ensure technical performance and long-term stability, it can be set into an overall structure in the initial stage.

           The metal material of the elastic element can play a key role in the comprehensive performance and long-term stability of the Fuel Oil Pressure Sensor. Therefore, it is necessary to select a material with high strength limit and elastic limit, low elastic modulus time and small residual stress caused by machining and heat treatment.

           Mechanical processing and heat treatment, during the mechanical processing of elastic components, because of the large residual stress caused by uneven surface deformation, the larger the amount of cutting, the greater the residual stress, so the residual stress generated by grinding It will be bigger. Therefore, the tempering process must be used to generate internal stress in the opposite direction, so that the residual stress can be offset with each other, thereby reducing the effect of the residual stress.
