The invention relates to an ultrasonic-based measuring sensor (10a - 10e), like distance sensor or dead angle sensor, having a membrane element (16) that can be electrically exited to vibrations by way of an actuating unit (20). According to the invention, the actuating unit (20) and/or the membrane element (16) are configured to carry out a heating mode that is modified with respect to the measuring mode, wherein the membrane element (16) heats up to a temperature (T), which is above an ice-formation temperature, and the heating mode comprises an actuation of the membrane element (16) that is extended or/and a at higher frequency relative to the measuring mode.
