• Application

  The temperature and humidity measuring unit is used outdoors wherever ambient conditions need to be measured quickly, almost latency-free. The measured values may be further processed in building management or DDC/BMS systems, either directly or via measurement transducers

• Functional description

  Both the sensors are installed in one housing for protection against disturbing ambient influences (such as sun radiation, wind, rain etc.). The medium temperature is measured using a Pt1000 sensor, while the relative humidity is measured using a sensor with a synthetic hair element. The length of the maintenance-free synthetic-hair measuring element changes depending on the relative humidity, which allows the direct operation of a sensitive wiper resistor. The winding and the wiper are made of a gold wire alloy that ensures minimum transmission resistance and a secure contact. Two axial fixtures with mast mounting clips provide the required stability to the humidity and temperature sensor. Measuring medium: Gaseous, not corrosive.
