THERMASGARD
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 sur-
faces, for instance for surface temperature measurement at windows, for monitoring formation of
condensate, or as heating surface sensor, e.g. at windows or walls.
