What is the function of each structure of the sensor?
The structural functions of the sensor: 1. Sensitive element: It is a component that directly receives the measured physical quantity; outputs another physical quantity with a certain relationship. 2. Conversion element: It converts the non-electricity output of the sensitive element into electrical signals such as circuit parameters and current or voltage. 3. The basic conversion circuit converts the circuit into power for transmission and processing.
The role of each structure of the sensor: 1. Sensitive element: It is a component that directly receives the measured physical quantity; it outputs another physical quantity with a certain relationship. 2. Conversion element: It converts the non-electrical quantity output by the sensitive element into circuit parameters and current or voltage and other electrical signals. 3. The basic conversion circuit converts the circuit into electricity for transmission and processing.
The sensor mainly consists of three parts: the front end (sensing side), the shell, and the rear end (electrical side). These three structural modules can be combined into any sensor model. There are no restrictions between them. For a given sensing unit There is no specific unique shell. Also, there is no specific unique electrical interface for a given sensing unit. Understanding these building blocks is fundamental to a deep understanding of sensors.
Front end– The quality of the sensing technology of the sensing unit is the main influence on the application of the sensor. The use environment of the sensor is also very important, which should be considered in some applications. Generally, there are five options: inductance, photoelectric capacitance, magnetic Mechanical housing The choice of sensor housing depends on the environment in which the sensor will be used. Environmental factors include: space/size, mounting connections, physical factors of mechanical damage and exposure to liquids. Material selection: Metal (nickel plated brass……)< /p>
