Use:In heating, ventilation and air conditioning plants for acquiring the room temperature.
Type summary:
| Type reference | Measuring range | Operating voltage | Output signal |
| QAA2061 | 0...50 °C | AC 24 V ±20 % / DC 13.5...35 V SELV or class 2 (US) |
DC 0…10 V |
| QAA2061D | |||
| QAA2071 | 0...50 °C | DC 13.5…35 V SELV or class 2 (US) |
4...20 mA |
Equipment combinations:All systems or devices capable of acquiring and handling the sensor’s DC 0…10 V or 4…20 mA output signal.
Function:The sensor acquires the room temperature via its sensing element whose resistance value changes as a function of the temperature. This change is converted to a DC 0...10 V or 4...20 mA output signal, depending on the type of sensor. The output signal corresponds to the selected temperature range.
