Emerson’s Rosemount 2120 series of vibrating fork switches, which see action in demanding and safety-critical applications, are now for use in hygienic process environments.
Hygienic certificates enable them to end up used in sanitary and aseptic applications in industries such as food and beverage, pharmaceuticals and life sciences.
The Rosemount 2120 series of switches, based on vibrating short fork technology, have SIL 2 certification. The certification enables the fork switches to see use for critical overfill protection, high and low level alarm and pump control duties in a range of process applications.
Hygienic approvals are now available on tri-clamp process connections. The wetside is machined from solid 316 type stainless steel, guaranteeing zero porosity and increasing robustness, with several surface finishes available, including a new electropolished option.
“The Rosemount 2120 is designed to provide a quick response time, delivering a successful level detection solution across many process industries,” said Teddy Tzegazeab, Rosemount product manager, Emerson Automation Solutions. “Increasing the switch’s robustness and gaining hygienic approvals will enable customers to take advantage of its reliable switching capabilities in even more demanding applications.”
The Rosemount 2120 offers level monitoring even in sticky/viscous applications often associated with hygienic manufacturing processes.
The hygienic version of the Rosemount 2120 gained certification from the American 3-A Sanitary Standards organization and the European Hygienic Engineering & Design Group (EHEDG). The product ended up designed in accordance with FDA and ASME-BPE standards.
