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