ABSTRACT:
A sensor, preferably one of sub-miniature design, serves for measuring an acceleration (b). For this purpose, an electric signal representative of the acceleration (b) to be measured is generated by a sensor arrangement and evaluated as measured value. The sensor arrangement produces a predetermined logic signal when an acceleration threshold value is exceeded. In order to ensure high detection security and to obtain a computer-compatible signal, with the aid of an arrangement of small dimensions, one makes use of a plurality of sensors responding at different acceleration threshold values. The sensors are, preferably, designed as unilaterally fixed elastic tongues. The tongues are differently designed, with respect to their spring-and-mass properties, in order to provide different acceleration threshold values. They are arranged on a common substrate board and connected to a digital evaluation unit. A first bit pattern formed from the predetermined logic signals of the sensor is compared with second bit patterns. The second bit patterns are representative of physically possible or physically impossible conditions of the sensor arrangement. The logic signals are evaluated as a measured value only when the first bit pattern represents a physically possible condition.
