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.
