G
THERMASGARD ®
THERMASGARD ® ALTF 1 surface contact sensors are electric contact thermo meters
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 THERMASGARD
and passive output determines the temperature of a medium flowing inside a pipe (e.g.
water temperature) via the surface temperature.
®
THERMASGARD ALTF 1 is a tube contact resistance thermometer with strap and axial
feeler tube for temperature detection at piping and tubes (e.g. coldwater and hot-water),
or at heating sections for heating system control.
