Description
Model TT859 is a 2-wire temperature transmitter for RTD (Resistance Temperature Detector)
thermometers. The Temptran
TM
converts the RTD's signal into a 4 to 20 mA DC current. The
current changes according to the range in which the Temptran is calibrated: 4 mA at the lowest
temperature of the range, rising to 20 mA at the top of the range. The leads that supply power
also carry the current signal. The TT859 is FIELD RANGEABLE; the Zero and Span are adjustable
over -10 to 60°F and 35 to 150°F respectively allowing for re-ranging by means of a simple
calibration process.
