Self-checking, self-calibrating and self-diagnosing functions of smart sensors

Self-inspection, self-calibration, and self-diagnosis functions - ordinary sensors need to be regularly inspected and calibrated to ensure sufficient accuracy during normal use. These tasks generally require the sensor to be disassembled from the use site and sent to the laboratory or inspection department. The abnormality of the online measurement sensor cannot be diagnosed in time. With smart sensors, the situation is greatly improved. First, the self-diagnostic function performs a self-test when the power is turned on, and the diagnostic test determines whether the component is faulty. Secondly, it can be corrected online according to the use time, and the microprocessor uses the measurement characteristic data stored in the EPROM to compare and check.
