Sensor system with sensor unit for detecting physical values, e.g. pressure or temp

摘要

The sensor system includes an amplifying system (2) for amplifying the detected voltage and a voltage pulse counter conversion system (16) for transmitting a pulse signal (VO) with pulses of the number, which is proportional to the amplified detected voltage, corresp. to a data transmission required signal, supplied from the outside. The data transmission required signal is a current supply switch-on signal (Vcc) supplied from the outside. The voltage pulse counter conversion unit includes a pulse generator (20), a pulse control system (22), an ADC (17) and a pulse transmission circuit (19).
