We occasionally encounter some minor faults during the use of the sensor, such as abnormal display, no power supply, no signal output, etc. For the first time users encounter this situation, people will be overwhelmed, which will greatly affect the normal work progress. This time, we have summarized the possible fault inspection scenarios of the sensor, and we will understand them one by one. 1. Disconnection method This is a commonly used maintenance method after the sensor fails, in fact, the disconnection method can also be called its elimination method, the core idea of this sensor fault inspection method is to separate the circuit that may cause sensor failure and analyze it independently. This sensor fault checking scheme is suitable for relatively independent circuits that are connected to each other. Second, the substitution method At a glance at the name, you can understand that this sensor fault check method is to replace the components that may cause the failure with good components, so as to determine whether this “hypothesis” is true. Comparative law The comparison method refers to the comparison of voltage, current, resistance and other parameters with the faulty machine with a normal circuit, and the premise of this sensor fault check method comparison is that the working state of the two machines should be consistent. Substitution and comparison, two sensor fault retention methods, can be applied to any current. The above three sensor fault inspection methods are simple to operate, highly targeted, and easy to master. Our on-site personnel who use and operate the sensors can quickly and accurately identify the point of failure, improving the efficiency of the entire workflow.
