OPTICAL REFLECTION-TYPE SENSOR

摘要

PROBLEM TO BE SOLVED: To simply check repeat accuracy in measuring an actual object at a place where a sensor is installed. SOLUTION: A signal processing part 3 of this optical reflection-type displacement sensor 1 measures the distance to the object each time reflected light is captured, further finds the moving average of the distances to output it as a measurement processing result, and also calculates the repeat accuracy of a prescribed number of sets of moving average data. A body 4 forming the processing part 3 is provided with a display part 35 where a plurality of digital displays 37a and 37b are arranged in lines. The processing result is displayed on the digital displays 37a in the upper line while the repeat accuracy is displayed on the digital displays 37b in the lower line.
