    Product introduction

    Selection of pressure sensors Modern sensors vary widely in principle and structure. How to select sensors reasonably according to the specific measurement purpose, measurement object and measurement environment is the first problem to be solved when measuring a certain quantity. When the sensor is determined, the matching measuring method and measuring equipment can also be determined. The success or failure of measurement results depends to a great extent on whether the selection of sensors is reasonable.

     

    Analysis on the development trend of the function of pressure sensor;

     

    1.Sensors that convert pressure into electrical signals are usually called pressure sensors. A pressure sensor usually consists of an elastic sensitive element and a displacement sensitive element (or strain gauge). The function of elastic sensor is to act the measured pressure on a certain area and convert it into displacement or strain, and then convert the displacement sensor (see displacement sensor) or strain gauge (see resistance strain gauge and semiconductor strain gauge) into pressure-related electrical signals. Sometimes, the functions of these two elements are integrated, such as a solid pressure sensor in a pressure resistance sensor.

     

    2.Pressure is an important process parameter in production technology, aerospace and national defense industry. It not only needs fast dynamic measurement, but also needs digital display and recording of measurement results. The automation of large oil refineries, chemical plants, power plants and steel plants also needs to transmit pressure parameters remotely, and convert temperature, flow, viscosity and other pressure parameters into digital signals and send them to computers.

     

    3.Therefore, the pressure sensor is a highly valued and rapidly developing sensor. The development trend of pressure sensor is to further improve the dynamic response speed, accuracy and reliability, and realize digitalization and intelligence. Commonly used pressure sensors include capacitive pressure sensor, variable reluctance pressure sensor (variable reluctance sensor, metal element analyzer differential transformer pressure sensor), Hall pressure sensor, optical fiber pressure sensor (optical fiber sensor), resonant pressure sensor and so on.
