Siemens QFM4160

The Siemens QFM4160 is a duct sensor designed to measure both humidity and temperature accurately within HVAC systems. This sensor offers temperature measurement ranges of 0 to 50°C, 40 to 70°C, or -35 to 35°C, allowing flexibility depending on your application needs. It covers the full humidity range from 0 to 100%, providing precise environmental monitoring. The device outputs a 0-10V signal and operates on a voltage supply between 24 VAC and 13.5 to 35 VDC. With an IP65 rating, the sensor is well protected against dust and water ingress, making it suitable for demanding duct environments. Distributed by BSP Automation, the QFM4160 is a reliable choice for integrating humidity and temperature sensing in industrial or commercial ventilation setups.
