A/TTM1K-A-50'-4-4X

A/TTM1K-A-50'-4-4X is an A/TTM1K series 1kohm matched RTD/transmitter. The copper averaging sensor is designed to be installed in medium to large ducts or air handling units where moisture, UV light air treatment equipment, critical temperature control, higher corrosion resistance and faster response times when compared to similar aluminium sensing elements. The copper has also been proven to provide an anti-bacterial effect on moulds, fungus and other bacteria typically found in ducts. Applications include rooftop units, air handlers, monitoring supply/discharge/return/mixed air temperatures, data centres, hospitals, laboratories.
