Siemens QAH11 floor temperature sensor
- For Siemens thermostats
- The sensor is a resistive NTC sensor
| Producer | Siemens |
The sensor measures the temperature of air or other media using a resistive NTC sensor. The resistance value, which varies depending on the measured temperature, is then processed by the controller.
The QAH11.. cable temperature sensors are used for temperature measurement in heating and ventilation systems. Due to their isolation, these sensors are particularly suitable for controllers whose input signal terminals are not galvanically isolated from the 230 V AC supply voltage.
They are used to measure these quantities:
Measurement of the discharge air temperature
Water temperature measurement (for switching heating/cooling modes)
