2. Classification of sensors

There are many types of sensors and many classification methods.

(1) Classification according to the physical quantity measured

① The displacement sensor is used for measurement of length, thickness, strain, vibration, and deflection angle. It can be divided into linear displacement sensors and angle displacement sensors.

② Speed sensor, used for measurement of parameters such as line speed, vibration, flow, traffic, momentum, speed, angle speed, angular momentum, etc., can be divided into line speed sensors and angle speed sensors.

③ Acceleration sensor is used to measure parameters such as the acceleration of the line, vibration, impact, quality, stress, corner acceleration, angle vibration, angle impact, and torque.

④ Force and pressure sensors are used for measurement of parameters such as force, pressure, weight, torque and stress.

(2) Classification according to the principle of working

① The resistance sensor is made of the principles of the geometric size of the resistance wire or resistance tablet using the contact of the mobile potentiometer. It is mainly used for measurement of parameters such as displacement, force, pressure, strain, torque, air flow rate, liquid flow.

② The inductive sensor is made by using the geometric size or position of changing the magnetic circuit to change the inductor and the principle of the inductance of the inductance and interoperability. It is mainly used to measure parameters such as displacement, pressure, force, vibration, and acceleration.

③ The capacitive sensor is made by changing the geometric size of the capacitor or changing the nature and content of the capacitor media to change the principle of electricity capacity. It is mainly used for parameters and other parameters such as measurement level, pressure, liquid level, thickness, and moisture content.

④ Resonant sensor is made by using the inherent parameters of changing the mechanical or electricity to change the principle of resonance frequency. It is mainly used to measure pressure.

The above four sensors are all electrolytic sensors. In addition, there are also electric sensors, such as the potential sensor, which uses the thermal power effects, photoelectric effects, Hall effects, or electromagnetic effects. , Current, current, speed, light, thermal radiation and other parameters; charge sensors are made of the principle of voltage effects, which is used for measurement of force and acceleration.
