Common sensor fault performance and treatment

With the development of science and technology, the methods of sensor fault diagnosis are more and more abundant, which can basically meet the needs of daily use. Specifically, the common sensor fault diagnosis methods mainly include the following

The sensor can be described as the "neural network" of the control system, and once it fails, it may cause the whole system to work abnormally or paralyze. The author mainly describes several common sensor failures, and puts forward some treatment suggestions for reference.

2.1 abnormal display

In daily use, the sensor may display L.LL or H.HH and other garbled information, which affects the normal work of the whole control system. When the sensor displays L.LL, it may be because the internal catalytic element or thermal conductivity element is broken, or the short line between its element and the circuit board leads to the failure. In this case, the maintenance technician can open the back cover of the sensor for testing to determine whether the connection between the component and the circuit board is normal or not. If it is determined that the problem does not exist, it is necessary to check the internal situation of the component with the help of the multimeter resistance file. Once the resistance shows infinity, it can be concluded that the component is broken and then replaced. There are many reasons for the garbled display of the sensor, including the abnormal operation of the single chip microcomputer and the damage of the reset circuit. When the sensor appears "888", it is necessary to give priority to the fact that the distance between the sensor and the substation is too far, and it should be shortened appropriately. Abnormal sensor display represents a fault in a certain part, so we should constantly accumulate experience in work practice and summarize its causes in order to solve it quickly.
