Request Information
The T72 programmable HART® temperature transmitter is a two-wire transmitter with an analog output. It has measurement input for resistance thermometers (RTDs) in 2-, 3-, or 4-wire connections, thermocouples, and voltage signals. The transmitter can be programmed with a PC or HART® protocol hand-held terminal. This transmitter is available with or without a digital display, and can be mounted in a direct or remote general-purpose aluminum screw-cover housing. Certain configurations are specified with CSA-rated Intrinsically Safe and Explosion-Proof approvals for Hazardous Locations. There is also an optional Bluetooth® configuration.
