Patented quality product (Immersion sensor patent no. DE 10 2012 017 500.0)
Calibratable temperature measuring transducer
THERMASGARD
®
TM 43
with eight switch-
able measuring ranges, continuous linear output, straight protective tube, housing made from
impact-resistant plastic with snap-on lid. Calibratable temperature measuring transducer
THERMASGARD
®
TM 65
with eight switchable measuring ranges, continuous linear output,
straight protective tube, housing made from impact-resistant plastic with quick-locking
screws,
with ⁄ without optional display
. For the detection of temperatures in liquid or gaseous
media. For aggressive media, stainless steel immersion sleeves must be used. It is used e.g.
in piping systems, in heating technology, in storage tanks, in district heating compact
stations, in hot-water and cold-water systems, in oil and lubricant circulation systems, in
mechanical, apparatus and plant engineering as well as in the entire industrial sector. The
sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
