Description
Ceiling built-in temperature sensor
THERMASGARD® DTF
The THERMASGARD® DTF device is a small built-in resistance thermometre with passive output for in-wall installation, e.g. in plasterboard walls or suspended ceilings.
The DTF ceiling temperature measuring transducer is preferably installed in ceilings and walls. It blends in seamlessly with the overall architectural design and detects the temperature at the surface. The connecting head is pluggable for quick, easy mounting.
