Family Description

The Kele T85U 1000 ohm RTD rangeable transmitter is a range selectable, two-wire 4-20 mA RTD transmitter used with Type 85 1000Ω platinum RTD sensors. The transmitter is available in six standard ranges, or it can be set for any range between -30° to 280℉ (-34° to 156℃) with a minimum span of 40℉ (22℃). To adjust the T85U, 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 T85U 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.
