Siemens QFA3160 Humidity and Temperature Sensor monitor the building control systems and relay changes in humidity and temperature. Relative humidity and temperature in the QFA series /Temperature Sensors are especially suitable for applications. Where specific, a stable sensation of humidity is required. Normal available Models are rated 2% and 2 % respectively, for both humidity only and temperature sensing combination humidity. Sensors are provided with output signals of either 4 to 20 mA or 0 to 10 Volt.
