Abstract

An object of the present invention is to provide an automatic compensation sensor that can eliminate an exclusive input terminal for the compensation mode signal. To achieve this object, the present invention comprises a sensor body (1), a signal output terminal (5) for outputting signals from the sensor body (1), and a controller for compensating the output signal from this signal output terminal (5).
