Amplifier device for sensors |
摘要 |
Amplifying device for a sensor (10) delivering a response in voltage or impedance comprising: voltage controlling means (22 connected to output terminals (16, 20) of the sensor to maintain a noticeably constant voltage between the said terminals, at least an additional impedance (12) connected in series with the sensor within a polarisation circuit, between the output terminals (18-16; 18-20) of the said device. Application to temperatures, irradiation levels and pH measurement.
