ALTF 1
surface contact sensors are electric contact thermometers and 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 ALTF 1 with connection cable and passive output determines the temperature of a
medium flowing inside a pipe (e.g. water temperature) via the surface temperature. ALTF 1 is
a tube contact resistance thermometer with strap and axial feeler tube for measuring tempera-
ture on piping and tubes (e.g. cold-water and hot-water), or at heating sections for heating
system control.
