Abstract
A device is disclosed for suppressing deviations in the output voltage of a pressure transducer in magnetic tape recorders caused by temperature fluctuations. A voltage dependent on the temperature of the pressure transducer is connected to the adjustable tap of a potentiometer connected between inputs of a differential amplifier. An operational amplifier compensates the output voltage of the pressure transducer with the output of the differential amplifier.
