Oil pressure sensor 25070-CD00A Air conditioning pressure 0-600bar

The working principle of the gasoline pressure sensor is:

The pressure directly acts on the diaphragm of the sensor, so that the diaphragm generates a micro displacement proportional to the medium pressure, so that the resistance of the sensor changes, and the electronic circuit detects this change, and then converts a standard signal corresponding to this pressure.

In industrial production, some product quality indexes (such as viscosity, hardness, surface smoothness, composition, color and taste, etc.) can not be measured quickly and directly by using traditional sensors and can not be controlled online. The intelligent sensor can directly measure some quantities (such as temperature, pressure, flow rate, etc.) in the production process that have a functional relationship with the product quality index, and the mathematical model established by neural network or expert system technology can be used to calculate and infer the product quality.

Automotive pressure sensors use one of the conventional oil pressure sensors

This automotive pressure sensor is the oil pressure control for the brake system with oil pressure booster. It detects the pressure of the reservoir, the close or break signal of the output oil pump, and the abnormal oil pressure alarm. Its structure is shown in the figure, and it is equipped with a semiconductor strain gauge, which takes advantage of the characteristic that the resistance changes when the shape of the strain gauge changes; In addition, there is a metal diaphragm, through the metal diaphragm strain gauge to detect the change of pressure, and convert it into an electrical signal after external output.
