The universal sensor switching module has been developped for humidity measuring applications and is suitable for various electrolytic sensors as a two-point controller.
The universal sensor switching module is suitable for various electrolytic sensors as a two-point controller. The circuit is provided especially for the evaluation of dew sensors of the SHS series or of the humidirty sensor EFS from our product range.
The evaluation of the sensor is based on an impedance measurement with alternating voltage. Due to this feature the electronics is suited for resistive and capacitive as well as electrolytic sensors. This functional principle with alternating voltage makes performing continouus measurements possible without destroying the sensors through electrochemical procedures.
Typical area of application
- Conductance and filling level probes
- Condensation switches or
- Water and leakage probes
