Abstract
A piezoelectric measuring device includes a sensor element that generates a measurement signal for a pressure and a data acquisition device to evaluate the measurement signal. The sensor element includes an operational amplifier with an inverting input and an output, a feedback capacitance in parallel with the inverting input and the output, and a reset switching element in parallel with the inverting input and the output. The operational amplifier provides an electrical supply voltage and the data acquisition device includes a measurement cycle circuit configured to activate the electrical supply voltage before a measurement cycle and deactivate after the measurement cycle. The sensor element includes a power-on reset logic to detect the electrical supply voltage accordingly close or reopen the reset switching element.
