Abstract of the Disclosure The invention provides a measuring and recording device comprising one or more transducers for generating electric signals in response to mechanical vibration arranged in an input circuit. A sensor is responsive to an analog/digital converter coupled to the input circuit and a time signaling circuit to supply an output device with vibration and time information for recording on a recording medium. A control circuit comprises a regulated voltage source in series with a comparator unit arranged between the input circuit and the analog/digital con- verter so that the voltage source supplies energy continuously to the input circuit and the comparator unit only. The comparator unit is designed so that upon receiving a signal of magnitude exceeding a pre-set threshold value it connects the regulated voltage source to a sequence generator designed to activate and control both the analog/digital converter and the sensor. In a preferred embodiment, the voltage source is located in a removable cartridge with the recording medium.
