Small surface contact resistance thermometer in aluminium enclosure (cable sensor). The
surface sensor
THERMASGARD
®
OFTF
is used for temperature detection on flat or slightly
convex surfaces, for instance for surface temperature measurement at windows, for monitoring
formation of condensate, or as heating surface sensor, e.g. at windows or walls.
