Description for Siemens QFM3160

The Q-Series Duct Relative Humidity and Relative Humidity & Temperature Sensors monitor and transmit changes in humidity and temperature to the building control systems. These units are especially suited for applications where precise, stable humidity sensing is required. Certified units are also available where certification is required. Several models are available ? for humidity only (in 5%, 2% and certified) or for humidity and temperature sensing (also in 5%, 2% and certified versions). The humidity only units are available in either 4 to 20 mA or 0 to 10 Volt signal versions. Combination humidity and temperature units are also available in either dual current or voltage versions, transmitting proportional signals back to the controller. Nickel 1000 ohm or Platinum 1000 ohm RTD temperature outputs on combination versions are also offered. 2% and certified versions are equipped with a removable, replaceable sensing tip. The removable sensing tips have a Lumberg connection that allows the user to screw off the tip without disrupting the installation or wiring. Siemens sensors with replaceable tips are ideal for applications where measurement accuracy is critical and sensor replacement is not an option. Replaceable sensing tips eliminate the need for accuracy adjustment. All certified sensors include a certificate of calibration. Humidity calibration and certification is based on a 3-point process at 20, 50, and 85% rh @ 23C.
