The T142 programmable HART® field temperature transmitter is a two-wire transmitter with analog output. It has measurement input for resistance thermometers (RTDs) in 2-, 3-, or 4-wire connections, thermocouples, and voltage signals. The transmitter is available with or without a digital display. The unit can be programmed with a PC or a HART® protocol handheld terminal. The backlit LC display indicates the current measured value numerically and has a bar graph with limit value violation indicator. The T142 is approved by CSA, ATEX/IECEx for Intrinsically Safe, Non-Incendive and Hazardous Location applications.
