Emerson’s Rosemount 2120 series of vibrating fork switches are now suitable for use in hygienic process environments. Hygienic certificates enable them to be used in sanitary and aseptic applications in industries such as food and beverages, pharmaceuticals and life sciences.
Based on vibrating short fork technology, the robust switches require almost no maintenance and are easy to install and use. SIL 2 certification enables the fork switches to be used for critical overfill protection, high- and low-level alarm and pump control duties in a wide range of process applications.
Hygienic approvals are now available on tri-clamp process connections. The wet side is machined from solid 316 stainless steel, ensuring zero porosity and increasing robustness. Several surface finishes are available, including an electropolished option.
The product is designed to provide a quick response time, delivering a successful level detection solution across many process industries. Increasing the switch’s robustness and gaining hygienic approvals will enable users to take advantage of its switching capabilities in sanitary applications.
