THERMASGARD
Calibratable mean value temperature measuring transducer THERMASGARD
continuous output, fully active flexible sensor rod for mean value measurement, plastic-coated copper protective tube (sturdy version), terminal box
enclosure made of impact-resistant plastic and enclosure cover with quick-locking screws. This sensor is used for the detection of average tempera-
tures (mean values) 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 sensor. The mean value sensors are factory-calibrated.
Adjustment ⁄ fine adjustment by the user is possible (range and zero point are adjustable). The mean value sensor MWTM is available in lengths of
0.4...20 m and is delivered as standard with a mounting flange. Mounting clamps MK-05-M are available as optional accessories.
