Description
Immersion/ screw-in/ duct temperature measuring transducer
THERMASGARD® TM 65 - Modbus - T3
W-Modbus is a wireless-based further development of the proven Modbus
standard for the wireless connection of Modbus-enabled sensors,
controllers and devices. W-Modbus devices communicate via a wireless
radio link from LumenRadio - independently of the in-house Wi-Fi and
without leaving the proven protocol standards. Thanks to the reliable
and interference-resistant wireless network, entire buildings can be
networked and the majority of Modbus RTU cables can be replaced.

Patented quality product (immersion sensor patent no. DE 10 2012 017 500.0)
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.
