The Kele T5U and T63U Transmitters are field rangeable, two-wire 4-20 mA RTD transmitters designed for use with Type 5 nickel-iron sensors, the Precon Type 63 sensors, or the JCI TE6300 Series. Each one delivers reilable and accurate performance for a wide variety of applcations. This transmitter can be combined with any Type 63 Precon sensors incorporating the optional ″XW″ weather resistant box for a one package application solution. To adjust the temperature transmitter, set the DIP switches to match the desired range, and use the zero and span pots to fine tune. A high accuracy digital ohmmeter and decade box are required.
