Der THERMASGARD® ALTF 2 is a tube contact resistance thermometer with passive output, strap and terminal box housing made of impact-resistant plastic and with an housing cover with quick-locking screws.
The THERMASGARD® ALTF 02 is a cost-effective tube contact resistance thermometer, with passive output, strap and terminal box housing made of impact-resistant plastic and a snap-on lid.
ALTF 2/ ALTF 02 surface contact sensors are electric contact thermometers used for surface temperature measurement on solids, having at least one so-called contact area that is brought into contact with the surface to be measured. The surface contact temperature sensor determines the temperature of the medium flowing inside a pipe (e.g. the water temperature) via the surface temperature. The tube sensor is used for temperature detection on lines, pipes (e.g. cold and hot water) or on heating sections for heating system control.
