Description
Surface contact / tube contact temperature sensor
THERMASGARD® ALTF2
THERMASGARD® ALTF 2 is a tube contact resistance thermometer with
passive output, in an impact-resistant plastic housing with
quick-locking screws, incl.strap.
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. This
surface contact temperature sensor measures the temperature of a medium
flowing inside a pipe (e.g. the water temperature). This tube surface
sensor is used for measuring temperature on piping and tubes (e.g.
cold-water and hot-water), wor on heating sections for heating system
control.
