Rosemount 2120 Series Fork Level Switch Vibrating Level Switch Side Top Mount ATEX-Rated Glass Filled 2120D1AT1NAAA0000

Rosemount 2120D1AT1NAAA0000 Fork Level Switch is a vibrating level switch designed for high precision liquid level detection. Featuring a glass filled nylon housing suitable for side and top mounting, it is ATEX rated for use in hazardous environments. The device utilizes a piezo-electric tuning fork mechanism to detect changes in liquid density by frequency variation, ensuring reliable operation even under challenging conditions.

The forks are constructed from 316/316L Stainless Steel providing excellent corrosion resistance and compliance with hygienic standards. The fork length is a standard 44mm, offering precise level sensing capability. The switch supports a wide operating temperature range from - 40°C up to 150°C and withstands pressures up to 100 bar, making it suited for diverse industrial applications.

This Rosemount level switch has a PLC interface with a maximum DC voltage of 12V and maximum current of 500mA. It includes a non-asbestos gasket material and has certifications including CSA, EAC, and ATEX, ensuring dependable safety and performance in explosive atmospheres.

Designed for industrial, chemical, pharmaceutical, water treatment, and process manufacturing applications, it provides overfill protection, high and low point alarms, pump control, and run dry protection. The device is virtually unaffected by foam, turbulence, bubbles, or viscosity variations. The magnetic test point facilitates easy functional testing, and the adjustable switching delay prevents false triggering in splashing or turbulent liquids.

Industry applications include hygienic liquids, coating liquids, aerated liquids, and slurries where reliability and quick response are essential. The fork shape is optimized to meet rigorous hygienic polishing standards. This level switch is built for long-term maintenance-free operation with no moving parts or crevices.

Incorporates tuning fork technology for reliable level detection in liquids. Made with 316/316L Stainless Steel forks for chemical resistance and dual certification. Operates effectively in temperatures from - 40°C to 150°C.
