Immersion/ screw-in/ duct temperature measuring transducer THERMASGARD® TM 65 - Modbus - T3
Patented quality product (immersion sensor patent no. DE 10 2012 017 500.0)

Calibratable THERMASGARD® TM 65 - Modbus - T3 temperature measuring transducer with sensor tube, Modbus connection, in an impact resistant plastic housing with quick-locking screws, optionally with/without display, stainless steel protective tube (50–400 mm).

The duct temperature transmitter serves to detect the temperature in liquid or gaseous media. Use our stainless steel thermowells for aggressive media. Applications are found in heating engineering, ventilation and air conditioning ducts, pipes, storage systems, compact district heating stations, warm and cold water systems, oil and lubrication cycle systems, mechanical and systems engineering and the entire industry sector.
Innovative Modbus sensor with galvanically separated RS485 interface, selectable bus termination resistance, DIP switches for setting the bus parametres and bus address in current-free state, LEDs for telegram status display, two separate push-in terminals and a large back-lit three-line display with customised programming in the 7-segment range and dot-matrix ranges. The measuring transducer uses internal diagnostics to detect sensor breakage or shorts as errors. The error messages can be retrieved via Modbus and are shown on the display. The sensor is factory-calibrated and can be fine-tuned to ambient conditions by an expert.
