ABSTRACT:
An amplifying device for a sensor (10) delivering a response in voltage or impedance has a voltage controlling means for the sensor and at least an additional impedance (12). The voltage controlling means (22) is connected to output terminals (16, 20) of the sensor to maintain a noticeably constant voltage between the terminals. The additional impedance (12) is connected in series with the sensor within a polarization circuit, between the output terminals (18–16; 18–20) of the device. The amplifying device may be applied to temperatures, irradiation levels and pH measurement.
