SENSOR WITH MONOLITHIC ULTRASONIC ARRAY
A sensor and a method for detecting a position of the sensor relative to a guide surface, comprising a housing and an electronic analysis device which outputs measurement values for the position of the guide surface on the basis of the measurement signals. The sensor contains an ultrasonic transducer array, each of the two outer ends of which is additionally equipped with a respective reference ultrasonic transducer and a respective reflector surface flush with the reference piezo disc at a distance from the base side, said ultrasonic transducers and reflector surfaces being inclined by 45° relative to the base side and pointing towards one another, thus forming a reference measurement path with a known length between the two reference ultrasonic transducers. In the method for detecting the relative position, the measurement values are corrected with respect to environmental influences by measurements in a reference path.
