Siemens Building Technology QFA3171 Air Relative Humidity Temperature Sensor 4-20mA

Siemens QFA3171 Outside Air Relative Humidity and Temperature Sensor is an elaborate device for the accurate receipt of the environmental conditions of HVAC systems. This sensor measures both relative humidity and temperature, is for optimizing indoor climate control. Data are output to a 4-20 mA signal provided through reliable integration with building management systems, and it has a humidity output range of 0-100% RH. It measures 80 x 144 x 39mm and 0.36 lbs. If this sensor is embedded in HVAC systems, the users can monitor and control outside air condition and improve energy efficiency and indoor comfort. The QFA3171's real time data allows system operations to be adjusted to avoid overcooling or overheating, reducing energy consumption and improving system performance.
