with passive output
THERMASGARD® ALTF-1 surface contact sensors are electric contact thermometers, which are used for measuring surface temperatures of 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 THERMASGARD® ALTF-1 with connecting cable and passive output determines the temperature of a medium flowing inside a pipe (e.g. the water temperature) via the surface temperature. THERMASGARD® ALTF-1 is a tube contact resistance thermometer with strap and an axial sensor tube for temperature detection on piping and tubes (e.g. coldwater and hot-water), or on heating trains for heating system control
