This Siemens QFM3171 is a duct-mounted sensor that measures both humidity and temperature, each with a 4-20mA output signal, for use in building automation and HVAC control systems. It mounts directly in the ductwork to monitor conditions and send proportional current signals back to the controller. This is a genuine Siemens replacement part.
Confirm the part number against your equipment's parts list before ordering.
