THERMASGARD
Calibrateable mean value temperature measuring transducer THERMASGARD
ranges, 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 sen-
sors 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.
