Series Description
The Kele T71U Platinum RTD Rangeable Transmitter is a two-wire 4-20 mA transmitter designed for use with Type 71 100 Ohm platinum RTD sensors. The transmitter is available in three standard ranges, or it can be set for any range between 30 degrees to 250 degrees F (-34 degrees to 121 degrees C) with a minimum span of 40 degrees F (22 degrees C). To adjust the T71U, 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. The T71U has a special 20 mA loop calibration test signal to provide easy system verification. Simply move the bottle plug jumper from NORM to 20, and the transmitter will output a constant 20 mA. The Loop Up LED provides power indication for the 4-20 mA output.
