THERMASGARD® ATM2-wModbus LCD

Calibratable outdoor temperature transmitter THERMASGARD® ATM 2 - Modbus - T3, with Modbus connection, in impact-resistant plastic housing with quick-locking screws, optionally with ⁄ without display, measures temperature (-50...+150 °C). International system of units SI (default) is set to Imperial (via Modbus).

The surface-mounted sensor is used to measure the temperature in gaseous media. It is used outdoors or in damp rooms, in cold stores and greenhouses, in industry and in agriculture. Installation on external walls is preferably on the north side or in a protected location. In direct sunlight, the sun and ball impact protection WS 01 or WS 04 (accessories) must be used.

Innovative Modbus sensor with electrically isolated RS485 Modbus interface, switchable bus terminating resistor, DIP switch for setting the bus parameters and bus address in the 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.
