What Are The Categories Of Sensors
- Jun 01, 2018 -

Sensors can feel be measured information, and make information according to certain rules signal 隃 out or storage, or any other way. Types of sensors

There are many different types of sensors that need to be installed in different industries. What are the categories of sensors? What about the leakage current sensor specialist

Said:

1. According to the input volume, namely the measurement object:

If the input quantity is: temperature, pressure, displacement, speed, humidity, light, gas and other non-electric quantity, the corresponding sensor is called temperature transmission

Sensors, pressure sensors, weighing sensors, etc.

This classification method clearly explains the purpose of sensors and provides users with convenience to choose the needed sensors according to the measurement objects

The disadvantage is that this classification method is to classify sensors with different principles into one class, so it is difficult to find out how each sensor has common conversion mechanism

Sex and difference.

Therefore, it is unfavorable to master some basic principles and analysis methods of sensors. Because the same type of sensors, like piezoelectric sensors,

It can be used to measure acceleration, velocity and amplitude in mechanical vibration, as well as impact and force, but it works the same way

.

2. It can be divided into active sensor and passive sensor according to the action form.

Active sensor also has the function type and reaction type, this kind of sensor can send certain detection signal to the object under test, can detect the detection signal under test

The change in the measured object or the signal formed by the detection signal producing some effect in the measured object.

It is called action type to detect the change of detection signal and reaction type to detect the response. Radar and radio frequencies

Range detector is an example of action type, while photoacoustic effect analysis device and laser analyzer are examples of reaction type.

The passive sensor only receives the signal generated by the object itself, such as infrared radiation thermometer, infrared camera device, etc.
