Force sensor

In daily life, everyone can feel the existence of force, and the measurement and control of force has been paid more and more attention. The force sensor have been widely applied to the force sensitive measurement and control circuit assembled by people of insight in all walks of life in all aspects, the most applied force sensor is the resistance strain gauge force sensor.

1.Strain gauge sensor

The strain gauge is made up of sensitive grid, base, cover piece and lead wire, and the symbol is represented by "RF".

The gratings are made of gratings, which are most sensitive to stress changes along the longitudinal axis of the bar, adhering to the basement of the glial membrane with a cap on which the substrate and the cover play the role of protecting sensitive gratings, transmissibility surface strain and electrical insulation. The resistance strain gauge can not directly measure the force. It is necessary to paste the polyacrylate or high temperature phosphate and so on on the force surface of the elastic element, which can be used to detect the change of stress on the surface of the specimen. The attached object is called an elastic body. According to different elastomers, it can be used to measure different forces.

2.The force sensitive strain gauge

1) The force sensitive strain gauge in the force sensitive bridge is called a work piece, which is pasted on the elastic body.

The force-sensitive strain gauges for compensation are called compensators.

2)Detect a force sensor

 When detecting the force sensitive sensor, the resistance value can be directly measured with the multimeter. However, due to different manufacturing processes, the resistance value is slightly different.

3.The piezoelectric sensor

When a quartz crystal exerts pressure in a certain direction, its two surfaces will generate opposite charges, and the charge quantity is proportional to the pressure, which is called the piezoelectric effect, an object with piezoelectric effect is called a piezoelectric body.

The piezoelectric sensor is a self-generating type sensor, which converts non-electric quantity of force, pressure and acceleration into electric quantity. When detecting, the electric charge is generated due to the bending deformation when the piezoelectric piece is blocked by the current of the multimeter, and the piezoelectric ceramic piece is lightly struck or collided, the stylus wiggle is good.
