THERMASGARD
Calibratable mean-value temperature measuring transducer THERMASGARD
continuous output, in an impact-resistant plastic housing with quick-locking screws, optionally with/without display, with bendable sensor rod (fully active),
protective tube made from copper, plastic-coated, and anti-kink spring, incl. mounting flange. Calibratable mean-value temperature measuring transducer
THERMASGARD ® MWTM-SD (rod sensor 3 m / 6 m) with eight switchable measuring ranges, continuous output, in an impact-resistant plastic housing
with snap-on lid, with bendable sensor rod (fully active), protective tube made from reinforced thermoplastic hose and anti-kink spring, incl. mounting flange.
The sensor is used to detect the mean temperature (mean value) in gaseous media, e.g. in ventilation and air conditioning ducts over the entire cross
section or over a defined length. Laid along a meandering route, it uniformly detects the surrounding temperature, as a duct temperature sensor. For
proper mounting of the rod, mounting clamps MK-05-M (accessories) are available.The sensor is factory-calibrated; an environmental precision adjustment
by an expert is possible.
