Sensor classification
Sensor (English name: transducer / sensor) is a detection sensor,Can feel the information being measured,And will feel the information,According to a certain Regularity transformation into an electrical signal,Or other desired form of information output,To meet the information transmission, processing, storage, display, record and control requirements.
At present there is no uniform classification of the sensor method,But the more commonly used classification method is as follows:
1, according to the physical quantity of the sensor:Can be divided into displacement, force, speed, temperature, flow, gas composition and other sensors.
2, according to the principle of sensor work classification:Can be divided into resistors, capacitors, inductors, voltage, Hall, photoelectric, grating thermocouple and other sensors.
3, according to the nature of the sensor output signal can be divided into:A switch type sensor that outputs a binary quantity ("1" and "0" or "on" and "off");Output for the analog sensor;Output as a pulse or code of the digital sensor.
