The principle of pressure sensor

A pressure sensor is a sensor that converts physical and chemical quantities (such as pressure, temperature, flow, etc.) into measurable electrical signals. Its principles mainly include resistance strain type and capacitance type: 1. The resistance strain type pressure sensor connects the strain gauge on the pressure sensor into a measurement bridge to obtain the signal of pressure change; 2. The capacitance type pressure sensor is By measuring the effect of pressure on capacitance, it is converted into an electrical signal. In terms of application, pressure sensors are widely used in various manufacturing plants, construction sites, ships, automation control and other fields.

The pressure sensor is a sensor that converts physical and chemical quantities (such as pressure, temperature, flow, etc.) into measurable electrical signals. Its principles mainly include resistance strain type and capacitive type.

The resistance strain gauge pressure sensor connects the strain gauge on the pressure sensor into a measurement bridge to obtain the signal of pressure change. Capacitive pressure sensors measure the effect of pressure on capacitance and convert it into an electrical signal.

In terms of application, pressure sensors are widely used in various manufacturing plants, construction sites, ships, automation control and other fields. In manufacturing plants, pressure sensors are often used for pressure monitoring of process flows and detection of equipment operating status. On construction sites, pressure sensors are often used for pressure measurement of concrete, tensile testing of steel bars, etc. In the field of ships, pressure sensors are used for the control of oil pressure systems, monitoring of water pressure systems, etc. In the field of automation control, pressure sensors play an important role in measuring and controlling various physical quantities.

In addition, according to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. In addition, there are also types such as medical pressure sensors and heavy-duty pressure sensors. Heavy-duty pressure sensors have structures such as metal housings and cables or connectors. They are often used in environments with extreme temperatures and electromagnetic interference, and can measure the pressure of fluids such as coolant or lubricating oil.

In general, pressure sensors have broad application prospects in fields such as industrial automation and process control, and help achieve high-precision, intelligent pressure measurement and control.
