Outside temperature/ wet room temperature measuring transducers THERMASGARD® ATM 2 - Modbus - T3
Calibratable THERMASGARD® ATM 2 - Modbus - T3 outside temperature measurement transducer with Modbus connection, in an impact resistant plastic housing with quick-locking screws, optionally with/without display.
The on-wall sensor device serves to detect the temperature in gaseous media. It is used outside or in wet rooms, in cold storage buildings and greenhouses, in the industrial sector and in agriculture. Installation on outside walls is preferably performed on the north side or in a protected place. In cases of direct solar irradiation, we recommend using our WS 01 or WS 04 sun and ball-impact protection hood (accessories).

Innovative Modbus sensor device 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. 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.
