Description
The Siemens QFM3100 Duct Relative Humidity Sensor is intended to measure relative humidity in HVAC duct systems precisely. Output signal is 0–10 VDC at 24 VAC or 13.5–35 VDC to ensure the precise and reliable data transmission. It works from -40°F to 158°F and measures humidity 0 to 100% R.H. It is simple to install (more on that later) and dimensions of 80 mm, 88 mm and 39 mm. It is made of polycarbonate, a tough material able to withstand conditions inside of HVAC duct. This sensor is frequently used in commercial and industrial HVAC system to maximize system efficiency and air quality.
