The application circuit diagram of thermal conductivity gas sensor with RTD

Published:2011/8/14 22:01:00 Author:Ecco | Keyword: application circuit , thermal conductivity , gas sensor , RTD

The principle of the sensor: when it is in high temperature (200 to 800 ℃), the temperature of the sensor changes with the gas thermal conductivity, then the resistance of platinum resistor wire is detected. In the circuit, RA and RB are the platinum resistor wires, which are respectively used as detection device and temperature compensation element. Detection devices work according to temperature changes, so the bridge voltage requires a high stability. Compared to air, the hydrogen has larger thermal conductivity, which is easy to measure, therefore, the voltage stability of bridge is 0.1%.   (View)
