THERMASGARD ®
Calibrateable 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 feeler is used for the detection of average
temperatures (mean values) in gaseous media, e.g. in ventilation and air conditioning ducts over the entire cross section, or over a defined length.
Laid meander-like it detects evenly the surrounding temperature as 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 m ... 20 m and
as a standard is delivered including mounting flange. Mounting clamps MK-05-M can optionally be ordered as accessories.
