Motorola-IPMC761 Principle of gas pressure sensor
Motorola-IPMC761 Gas pressure sensor as a typical sensor, has been widely used, its working principle is a lot of people are more concerned about the problem, below we will introduce its basic principle and other information.
To know the structure and working principle of gas pressure sensors, we must first know the mechanical barometer. Common ones are fire extinguishers, boilers and so on.
It mainly uses two gas chambers, one connected with the reception gas pipeline and a closed standard atmospheric pressure chamber. In the middle is a bulbous diaphragm, supported by a spring. The air pressure directly affects the deformation of the spring and the pressure of the spring on the base, which is an inertial value.
If the varistor is installed between the spring and the base, the resistance will change its resistance in response to the spring’s deformation force, which in turn is affected by the air pressure. So the magnitude of the varistor is the ratio of the pressure.
Motorola-IPMC761 The role of the sensor circuit
What is the function of the sensor circuit? The sensor circuit determines the quality of the sensor, the quality of the sensor determines the pros and cons of the system, the role of the sensor circuit is great, the sensor circuit can be said to directly determine the production quality and production efficiency.
Motorola-IPMC761 In the process of industrial production, product quality and production efficiency are the two main indicators to measure the quality of all production activities. In order to obtain high efficiency and high quality of production, it is necessary to test and control the production process. In order to ensure the quality of products, the products produced by enterprises must be inspected; To increase productivity and automate, the health of production equipment also needs to be monitored. Modern high and new technology, cutting-edge technology, such as the production of large-scale integrated circuits, the launch and flight of aerospace vehicles Motorola-IPMC761 are inseparable from precision measurement; People’s modern life, office equipment is also more and more dependent on measurement, such as home appliances, cars, copiers, etc., are equipped with a variety of sensors, especially the pressure sensor in the car is extremely important, need to be measured and controlled so that it can successfully complete the intended function.
Motorola-IPMC761 Measurement and control system is generally composed of sensor, signal conditioning circuit and execution machinery; The monitoring and information acquisition system generally consists of a sensor, a signal conditioning circuit and a display or output part. Regardless of the function, the signal obtained by the sensor needs to be processed by the signal conditioning circuit. The signal conditioning circuit is a circuit that transforms and amplifies the signal and turns it into a strong signal that is easy to be processed later, which is generally called the sensor circuit. It is the key link to turn the signal acquired by the sensor into a direct application signal.
