QFM2160 | SIEMENS DUCT SENSOR FOR HUMIDITY (DC 0...10 V) AND TEMPERATURE (DC 0...10 V)

• Humidity measuring range 0 to 100%
• Measuring accuracy ±3 % within comfort range
• Signal output DC – 0 to 10V, 4-20 mA for relative humidity, temperature
• Temperature measuring range 0 to 50, -35 to 35 or -40 to +70 °C

The QFM2160 duct sensor is designed for use in air ducts found in ventilation and air conditioning plants for determining the relative humidity and the temperature. This versatile duct sensor can be used as a control sensor to ensure the supply or extracton of air, as a reference sensor such as when shifting dew point, limit sensor when in connection with steam humidifiers and connection to a building control and automation system. When using the sensors for minimum or maximum selection, for averaging, or to calculate enthalpy, enthalpy difference, absolute humidity, and dewpoint, use of the SEZ220 signal converter is recommend.
