THERMASGARD® ALTM1-wModbus LCD

Calibratable contact temperature transmitter (compact version) THERMASGARD® ALTM 1 - Modbus - T3, with Modbus connection, in impact-resistant plastic housing with quick-locking screws, pipe feeder, incl. clamping strap, optionally with ⁄ without display, measures temperature (-50...+150 °C). International system of units SI (default) is set to Imperial (via Modbus). With device variant wModbus, the W-Modbus (wireless) replaces
replaces the RTU cable, the BMS connection is radio-based via a W-Modbus gateway.

The pipe contact sensor is used to record the temperature on cables, pipes (e.g. cold and hot water) or on heating pipes for heating control.

Innovative Modbus sensor with galvanically isolated RS485 Modbus interface, switchable bus terminating resistor, DIP switch for setting the bus parameters and bus address in de-energized state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated, individually programmable in the 7-segment range and dot-matrix range). By means of self-diagnostics sensor break or sensor short circuit are recognized as errors. The error messages can be called up via the Modbus and are shown on the display. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
