Rosemount 2120 Series Fork Level Switch Vibrating Level Switch Side and Top Mount Glass Filled Nylon 2120D1AV1NAAA0000

Rosemount 2120D1AV1NAAA0000 Fork Level Switch is a vibrating liquid level switch designed for precise level measurement and control in various industrial sectors, including automation, water treatment, and chemical processing. It utilizes the tuning fork principle where a piezo-electric crystal causes the fork to oscillate at its natural frequency.

When immersed in a liquid, the vibration frequency changes based on the density of the fluid, enabling accurate liquid presence detection. The device supports both side and top mount configurations with a corrosion-resistant glass filled nylon housing and features a non-asbestos sheet gasket for sealing.

This level switch offers excellent operational temperature resilience from -40°C to 150°C and can handle pressures up to 100 bar, making it suitable for demanding environments. Electrical compatibility includes 30V DC maximum and 264V AC voltages with a maximum current of 500 mA, complemented by a DPCO relay for versatile control functions.

Designed with a robust fork that is resistant to the effects of turbulence, foam, vibration, and solids, it ensures reliable switching operations. The fast 'drip' fork design and adjustable switching delay avoid false triggers, particularly in turbulent or splashing applications. The device also incorporates a magnetic test point for easy functional testing.

Industrial use cases include overfill protection, high and low point alarms, pump control, run dry prevention, and hygienic liquid level monitoring. With its lightweight glass filled nylon construction and polished fork options, it suits hygienic and high-temperature environments effectively.

Durable glass filled nylon housing with M20 conduit threads. Non-asbestos sheet gasket material for enhanced chemical resistance. Side and top mounting flexibility for installation convenience. Electronics and relay components designed for robustness and reliability.

Highly responsive switching with fast wet-to-dry and dry-to-wet time settings. Heartbeat LED indicator signals switch status continuously. Suitable for liquids including aerated and slurries with coating compounds. Factory default standard fork length of 44 mm providing hygienic performance.
