Siemens QFM2160U

The Siemens QFM2160U is a duct relative humidity sensor designed to provide accurate monitoring of air moisture levels within HVAC systems. This sensor outputs a 0-10 VDC signal corresponding to a relative humidity range of 0 to 100%, allowing for precise integration into building automation controls. Additionally, it features a temperature output on the same 0-10 V scale, giving you reliable temperature data alongside humidity measurements. The probe comes with an adjustable insertion depth between 3.5 and 8 inches, making it adaptable to various duct sizes and installation requirements. Connections are made via a terminal block, ensuring straightforward wiring, though the unit does not include a display. Distributed by BSP Automation, the QFM2160U offers a practical solution for controlling and monitoring indoor air quality.
