The non-electrical parameters collected by resistance sensors mainly include the following:
1. Force: Resistance sensors can measure the magnitude of force by converting force signals into changes in resistance values. This type of sensor is widely used in industrial automation, robotics, aerospace and other fields.
2. Displacement: Displacement is another common non-electrical parameter. Resistance sensors can convert changes in the position of an object (i.e. displacement) into changes in resistance values. For example, strain gauge displacement sensors are an application based on the principle of resistance sensors.
3. Pressure: Resistance sensors can also measure pressure and convert changes in pressure into changes in resistance values. This type of sensor plays an important role in pressure measurement, liquid level control, air pressure monitoring and other fields.
4. Acceleration: Some resistance sensors can also measure acceleration, a non-electrical parameter. Through specific design and working principles, resistance sensors can sense changes in acceleration and convert them into changes in resistance values.
5. Temperature: Although temperature is usually regarded as a thermal quantity, in some cases, resistance sensors are also used to measure temperature. Thermistors are a typical resistance sensor that can measure temperature and convert it into changes in resistance values.
6. Other non-electrical parameters: In addition to the above-mentioned common non-electrical parameters, resistance sensors may also be used to measure other non-electrical parameters, such as strain, torque, etc. The specific measurement of these parameters depends on the type and design of the resistance sensor.
It should be noted that there are many types of non-electrical parameters collected by resistance sensors, which depend on the type, design and application scenario of the sensor.
In practical applications, it is necessary to select a suitable resistance sensor to measure the required non-electrical parameters according to specific needs.
In addition, the working principle of resistance sensors is usually to convert the measured non-electrical quantity (such as force, displacement, pressure, etc.) into a change in resistance value, and then convert the change in resistance value into electrical quantity output such as voltage and current through a conversion circuit.
This conversion process makes resistance sensors have broad application prospects in industrial automation, measurement and control and other fields.
