T85U Temperature Transmitter
Brand: KeleThe Kele T85U 1,000 ohms RTD range-able transmitter is a range selectable, two-wire 4-20 mA RTD transmitter used with Type 85 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 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.
Features- Class a sensors Dip switch range-able Loop calibration test signal Snap-track mounting Loop-powered LED indication Fits into card slot of ST-U85 housing CE approved (commercial and industrial) Available as a complete assembly Conformal coated
