What are the sensors of the engine?

The sensor is a detection device, and it also has the image of the sensor, that is, the electric five senses. Because the sensor is an extension of human five senses, people need to use the five senses to feel the outside world and get information from the outside world. However, for natural phenomena and laws or activities in production, the five senses of human beings are far from achieving the imagined effect. So sensors have been developed, so what are the sensors? Power transmitter expert Xin introduced:

What is a sensor?

1. structural sensor

Structural sensors rely on the change of sensor structural parameters to realize signal conversion. For example, capacitive sensor, depending on the change of the distance between plates, causes capacitance change; Inductive sensors rely on armature displacement to cause changes in self-inductance or mutual inductance.

2. Passive sensors

Passive sensors cannot directly convert the energy form, but can control the energy input from another input or excitation energy. Sensors undertake the task of converting specific characteristics of an object or process into quantities. Its "object" can be solid, liquid or gas, and their state can be static or dynamic (that is, process). After transformation and quantization, object features can be detected in many ways.

3. Physical sensor

Physical sensor relies on the change of physical properties of sensitive element materials to realize signal conversion. For example, mercury thermometer measures the temperature by using the phenomenon that mercury expands with heat and contracts with cold; Piezoelectric dynamometer is made by using the piezoelectric effect of timely crystal.

4. Energy control sensor

The energy control type sensor operates by providing auxiliary energy from the outside, and controls the change of the energy provided from the outside through measurement. For example, in resistance strain measurement, the strain gauge is connected to the bridge, and the working energy of the bridge is provided by the outside world. The unbalance degree of the bridge is controlled by the resistance change of the strain gauge caused by the measured change. Such as inductance micrometer and capacitance vibrometer. Belong to this type.

From the above, it should be easy to see which sensors are available. If you need a leakage current sensor or power transmitter, you can consult or buy it from Xinrida.
