Mean value temperature measuring transducer THERMASGARD® MWTM - Modbus - SD

Calibratable THERMASGARD® MWTM - Modbus mean value temperature measuring transducer (rod sensor) with Modbus connection, 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 temperature transmitter serves 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 as a duct sensor, it uniformly detects the surrounding temperature. The mean value temperature measuring sensor is factory-calibrated. Adjustment/Fine-tuning by the user is possible (zero-point offset is adjustable). The MWTM transmitter 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 accessory.
