THERMASGARD® MWTM-SD-U 3M

Item No. 1101-3131-0239-90K
EAN 4 251325 617046

Calibratable mean value temperature measuring transducer THERMASGARD® MWTM (rod sensor) with eight switchable measuring ranges, continuous output, with flexible, fully active sensor rod and plastic-coated copper protective tube (rugged design), with terminal box housing made of impact-resistant plastic, housing cover with quick-locking screws. The sensor is used to detect 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 along a meandering route, it uniformly detects the surrounding temperature, as a duct temperature sensor. The mean value sensors are factory-calibrated. Adjustment/ fine adjustment by the user is possible (range and zero points are adjustable). The MWTM is available in lengths of 0.4...20 m and includes a mounting flange as standard. Optional MK-05-M mounting clamps can be ordered as accessories.
