Abstract
A sensor for measuring accelerations has a small plate 1 which is arranged in a housing 3 perpendicular to a direction of measurement 11, and is clamped at its edges with the interposition of flexural soft regions 2. There is, furthermore, provided a transmitter-receiver unit 4a, 4b which is so arranged in the housing 3 on a path compensator 12 that rays coming from the transmitter 4a are reflected by the small plate 1 onto the receiver 4b. Thereby an electrical signal is formed which serves to control the voltage 13A outputted by the path compensator 12. In a further embodiment of the invention, there are two transmitter-receiver units which are so arranged in a housing 23 that the rays coming from the transmitters 24a are reflected by the front and back of the small plate 1 onto the receivers 24b.
