Rosemount™ 848T Temperature Transmitter

The Rosemount 848T Temperature Transmitter delivers a best-in-class solution for high density temperature measurement applications. It is the ideal transmitter for obtaining up to eight temperature measurements in close proximity to each other, which reduces wiring costs and simplifies installation. Engineered with Emerson’s measurement validation diagnostic, this transmitter helps you predict on-scale failures and avoid unnecessary shutdowns, increasing safety and productivity.

Challenge

Achieving and repeating Golden Batch outcomes is your goal. Many facilities operate with a Right-First-Time metric between 40-70%. Bad batches increase cycle times because they require rework or worst case, even scrapping.

Users tell us that up to 62% of work performed by staff is non-value add including unnecessary operator rounds that waste precious hours on the process. Also, manual measurements have inherent safety risks to employees.

Our Solution

Utilize Emerson solutions in the batching process application and you can consistently hit quality and production targets while having a safe and reliable operation.
