Discontinued - replaced by Rosemount-Emerson 475

The Rosemount HART 375 Field Communicator is built on over ten years of experience with the 275 HART Communicator. It is a universal, user upgradeable, intrinsically safe, rugged and reliable portable communicator that will support all your fieldbus devices.

The HART 375 Field Communicator runs on Windows CE, a robust, real-time, operating system. The display uses transflective technology, making it easy to read in both bright sunlight and in normal lighting. It also includes a multi-level backlight, allowing the display to be viewed in those areas of your plant with dim light. The touch sensitive display and large physical navigation buttons provide for efficient use both on the bench and in the field.
