Self-check, Self-calibration, And Self-diagnosis Functions Of Smart Sensors

Ordinary sensors need to be inspected and calibrated regularly to ensure sufficient accuracy during normal use. These tasks generally require the sensor to be disassembled from the site of use and sent to the laboratory or inspection department. The abnormality of the online measurement sensor cannot be diagnosed in time. The situation of using smart sensors is greatly improved. First, the self-diagnostic function performs self-check when the power is turned on, and diagnostic tests to determine whether the components are malfunctioning. Secondly, it can be corrected online according to the time of use, and the microprocessor uses the measurement characteristic data stored in the EPROM for comparison and verification.
