The force sensor is an electronic component that transforms the force signal into a electrical signal output.The force sensor is mainly composed of three parts: Limin elements (that is, elastic body, common materials are aluminum alloy, alloy steel and stainless steel).Conversion elements (the most common is resistance strain tablets).The circuit part (generally there are lacquer cables, PCB boards, etc.).
Force sensor type
Stress tube type.There are 2 or 4 tablets on the wall of the tube wall. Half of which are posted on the solid part as a temperature compensation film, and the other half is used as a measuring strain film.When there is no pressure, the four -piece full -bridge circuit forms a balanced film; when the pressure is acting on the inner cavity, the cylinder is deformed into a "waist drum shape", causing the bridge to lose balance, and the output and pressure become a voltage of a certain relationship.This sensor can also use the piston to transform the measured pressure to the force to transmit the measurement pressure on the strain tube or the diaphragm -shaped membrane -shaped membrane shape.The structural of the strain -type pressure sensor is simple, convenient, and applicable. It is widely used in the dynamic pressure measurement of rockets, artillery and artillery.
Power sensor calibration
The sensor adopts real -time calibration method, that is, instant calibration and calibration of the sensors used in the pressure measurement system at the scene. Therefore, the error generated by the temperature and sensitivity offset of the sensor can be eliminated, and the test accuracy of the sensor is further improved.To achieve real -time calibration of the pressure sensor, a higher precision program control benchmark source must be provided. For example, the US 780B electronic scanning system or 8400 system is used to use the pressure benchmark of 0.02%accuracy, which can give the program control to give different benchmark air pressure.
Application of force sensor
The force sensor is mainly used in various electronics, industrial control areas, online control, safe overload alarm, material test machine and other fields.Such as electronic vehicles, electronic platforms, electronic forklifts, dynamic shaft heavy scale, electronic hook scales, electronic pricing scales, electronic steel scale, electronic rails, fighting scales, ingredients scale, canned scale, etc.
The role of force sensor
In fact, the more complex strain tube type and the strain beam belong to this type.Feeling components include membranes, film boxes, ripple tubes, Polyon tubes, etc. The elastic strain elements include cantilever beams, fixed beams, π -shaped beams, ring -shaped beams, thin -walled cylinders, etc.They can be combined into multiple types according to different needs.The strain pressure sensor is mainly used to measure the dynamic or static pressure of the flowing medium, such as the pressure of the import and export gas or liquid of the power pipeline equipment, the pressure of the internal combustion engine pipeline, and so on.
Power sensor working principle
The force sensor uses most of the mechanical principles, which includes three parts of the theory of mechanical theory. Therefore, it is called a force sensor. The type of force sensor is also diverse, but the main principles are similar because they are as good as the same as they are, because they are all as possibleThe force is correlated, so the force sensor is also widely used in the weighing link. It is understood that the force sensor is applied in many ground pumps to weigh some large -scale mobile objects.
