Product Description
Siemens QFA2001
The Siemens QFA2001 is a room sensor designed for acquiring relative humidity and temperature in indoor environments. It is primarily used in heating, ventilation, and air conditioning (HVAC) systems to provide accurate measurements for building automation and control systems. The sensor delivers reliable performance with its capacitive humidity sensing element and Pt1000 temperature sensing element, outputting DC 0…10 V signals for both measurements, making it suitable for a wide range of climate control applications.
