Kele Temperature Transmitter, T71U

T71U Temperature Transmitter

Brand: Kele
Add Product to My Catalog

The Kele T71U platinum RTD range-able transmitter is a two-wire 4-20 mA transmitter designed for use with type 71100 Ohms platinum RTD sensors. 

The transmitter is available in three standard ranges, or it can be set for any range between -34° to 121° C (30° to 250° F) with a minimum span of 22° C (40° F). 

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.
