Siemens Building Technology QFA32SS.EWNN Room Humidity Temperature Sensor 0-10V/4-20mA

The Siemens QFA32SS.EWNN Room Humidity and Temperature Sensor is one of the best devices that can be used for precise control of HVAC systems. This sensor offers comprehensive information on the status of indoor environment through measuring temperature of 32°F – 122°F and humidity of 0 – 100% RH. Due to the availability of two output signals; 0-10V and 4-20mA, it may be easily interfaced with different HVAC systems. It operates with a working voltage of 18 to 36 Vdc and can be employed in different control circuits. This sensor is ideal for application in HVAC systems: residential, commercial and industrial where proper monitoring and controlling of temperature and humidity is crucial.
