Pressure sensors are often used in the safety control system, the main areas for the compressor's own safety management system. There are a lot of security control in the field of sensors, pressure sensors as a very common sensors Pressure sensors price, in application of the safety control system is not surprising. Applications generally from the performance aspects to consider in the field of security controls, from considering the price, as well as from the actual operation of safety convenience to consider the actual effect of selection pressure sensor proved very good. Pressure sensors use mechanical equipment to some of the elements of process technology and signal conditioner and other devices installed in a very small chip on it. So small is one of its advantages, in addition to high-precision pressure sensor, cheap is it another big advantage. To some extent, it is possible to improve the accuracy of system testing. In the safety control system by installing a pressure sensor in the outlet pipe equipment to a certain extent, the pressure control of the compressor, which can be considered certain protective measures, but also a very effective control system. When the compressor starts normally, if the pressure does not reach the upper limit, the controller will open the intake port so that by adjusting the equipment to achieve maximum power. Select the pressure sensor when the need to pay attention to a lot of problems, for example, the pressure sensor range, accuracy, temperature characteristics of the pressure sensor, chemical properties are to be considered miniature pressure sensors, pressure sensors and practices also need to consider important issues. For example measuring sensors for measuring gas pressure and liquid pressure situation is different. Gas is a compressible fluid, it will increase the storage time can seize certain compression, decompression time and kinetic energy released from a pressure sensor, a shock wave is applied to the sensor elastic membrane. Pressure sensor requires a greater overload. The liquid is incompressible fluid, when the pressure sensor is installed, tightened bolts nor compressible space can increase the pressure exceeds the elastic limit of the pressure of the liquid film, resulting in the elastic membrane rupture pressure sensor model, a pressure sensor, Xinfeng Xinxiang Xinfeng Sensing purification technology Limited.
