Kele 1000 Ohm 375 Platinum RTD Rangeable Transmitter T91H, T91L, T91U Series

Kele 1000 Ohm 375 Platinum RTD Rangeable Transmitter

 

The T91H, T91L, T91U 1000Ω 375 Platinum RTD Rangeable Transmitters are a family of transmitters designed for multirange applications for HVAC, industrial and building automation uses. The T91U is a range selectable, two-wire 4-20 mA RTD transmitter used with Type 91 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 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. The T91H and T91L are specialty units for very high temperatures and very low temperatures, respectively. Both units are rangeable within their specialty limits.
