The difference between different sensors
Sensor:
The sensor is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information transmission, processing, storage and display. Requirements for recording, control and control.
Sensor characteristics:
Miniaturization, digitization, intelligence, multi-functionality, systematization, and networking. It is the first step in achieving automatic detection and automatic control. The existence and development of the sensor allows the object to have senses such as touch, taste and smell, and let the object slowly become alive.
Classified according to its basic perception function:
Ten categories of thermal elements, photosensitive elements, gas sensors, force sensitive elements, magnetic sensors, humidity sensors, acoustic sensors, radiation sensitive components, color sensitive components and taste sensitive components.
Fiber optic sensor and photoelectric sensor
In fact, fiber optic sensors should belong to one of the photoelectric sensors. Relatively speaking, fiber optic sensors are generally more accurate than ordinary photoelectric sensors. Ordinary photoelectric sensors refer to direct illumination and light collection on the sensor, due to the diffusion of light, etc. The size of the received light cannot be precisely controlled, that is, the accuracy of the detection cannot improve the accuracy, and the optical fiber sensor transmits light through the optical fiber line, improves the degree of convergence of the light beam, and is easy to judge the amount of light received, and the detection precision is high.
Contact and non-contact sensors
The contact type is that it must be contacted to have a signal, such as a pressure sensor, a temperature sensor, and the like.
Non-contact means that signals can be generated without contact, such as acoustic sensors, chemical sensors, and the like.
