Kele Temperature Transmitter, T91* Kele Temperature Transmitter, T91*
The Kele T91U 1,000 ohms RTD range-able transmitter is a range selectable, two-wire 4-20 mA RTD transmitter used with Type 91, 1,000 ohms platinum RTD sensors. 

The transmitter is available in six standard ranges, or it can be set for any range between -34° to 156° C (-30° to 280° F) with a minimum span of 22° C (40° F). 

To adjust the T91U, 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 T91U 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.
