THERMASGARD
Patented quality product (Immersion sensor patent no. DE 10 2012 017 500.0)
Calibratable temperature measuring transducer with sensor tube THERMASGARD
resistant plastic housing with quick-locking screws, stainless steel-protective tube (50 - 400 mm / 2 - 16 in), optionally with ⁄ without display, measures
temperature (– 50...+ 150 °C / – 58...+ 302 °F). International system of units SI (default) can be changed to imperial (via Modbus).
The duct sensor is used to detect the temperature in liquid or gaseous media. Use the stainless steel immersion sleeves for aggressive media. It is
used 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, machine and systems engineering and the entire industry sector.
Innovative Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance, DIP switch for setting the
bus parameters and bus address in current-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line
display (illuminated, with customised programming in the 7-segment range and dot-matrix range). Uses internal diagnostics to detect sensor breakage
or sensor short circuit as errors. The error messages can be retrieved via Modbus and are shown on the display. The sensor is factory-calibrated; an
environmental precision adjustment by an expert is possible.
