S+S Regeltechnik THERMASGARD ALTM2 [6/16] Endless strap with metal tightener included in the scope of delivery
Calibratable surface-contact temperature measuring transducer
THERMASGARD
®
ALTM 1
(compact variant) and
ALTM 2
(detached variant) with eight
switchable measuring ranges, continuous output, in an impact-resistant plastic housing with quick-locking screws, optionally
with ⁄ without
display, cable sensor with a pipe feeder
(ALTM 2)
, incl. strap.
The surface-contact sensor is used to detect the temperature on lines, pipes (e.g., cold and warm water) or on heating sections for heating control. The
sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
