Emerson has introduced its new Rosemount™ 550pH sensor and Rosemount 550DW dissolved oxygen sensor adaptor.

The new Rosemount™ 550pH single-use sensor and the Rosemount 550DW dissolved oxygen single-use sensor adapter are designed to deliver the same stability and performance as Emerson’s stainless-steel sensors.

The Rosemount 550pH sensor offers unique capability of being stored wet for immediate verification and standardisation, eliminating the initial stabilisation process, which can generally slow start-up by 30 minutes to two hours.

“Emerson engineers have designed our new single-use sensors to perform as well as or better than those used in stainless-steel bioreactors. Wherever possible, we’ve maintained our industry-standard designs so that users and OEMs need no additional training to be up and running.”

“At the same time, we’ve added features, like the wet storage, that overcome challenges that have been plaguing single-use process since it’s advent. Our customers spoke, and we listened,” Francis continued.

The Rosemount 550pH sensor is an electrochemical, fully disposable device with sensor stability of less than 0.005 pH change per day verified by extensive testing. The sensor provides up to ten times enhanced stability and requires no maintenance or calibration after initial one-point standardisation.

The new Rosemount 550DW dissolved oxygen (DO) sensor adaptor is compatible with standard stainless-steel DO sensors and enables placement into the bioreactor single-use bag.

Both the Rosemount 550pH sensor and the Rosemount 550DW dissolved oxygen sensor adapter operate with the advanced Rosemount liquid analytical 56 transmitter. The new sensor technologies and the Rosemount 56 transmitter are fully compatible with Emerson DeltaV™ control system.

“Emerson has delivered the level of sensor performance demand by biopharmaceutical processing users in a single-use design that is efficient, highly stable, easy to use and cost effective,” Francis concluded.
