Temperature sensors with current transmitter TS-45x are used for accurate temperature supervision indoors or outdoors with the presence of direct sunlight. They are developed for meteorological and industry purposes in automated systems using SCADA. Two wire connection provides power and signal transmission. The device is designed for vertical mounting. Robust construction and high overvoltage immunity enable resistance against toughest conditions outdoors and in chemically aggressive environments such as salt warehouses, chemical pools, mines, tunnels, etc.
