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