7ML5731-1AA11-1AA0 SIEMENS Exclusive SITRANS LVS200 Vibrating Fork Point Level Switch Original Brand New

The SIEMENS 7ML5731-1AA11-1AA0 SITRANS LVS200 is a premium vibrating fork point level switch designed for reliable detection of dry bulk solids. With its robust construction, advanced electronics, and adaptable design, it is the ideal solution for level monitoring in bins, hoppers, and silos. The device operates using a vibrating fork principle, ensuring accurate level detection even in demanding industrial environments where mechanical stress, dust, and vibration are common. Its versatility allows the LVS200 to handle bulk densities as low as 20 g/l in standard applications, or as little as 5 g/l with the low-density option. This flexibility makes it suitable for a wide range of industries including cement, chemical, food, and mining.

The 7ML5731-1AA11-1AA0 is built with a rugged stainless-steel housing, ensuring long service life and resistance to wear. The fork is designed to stay clean, reducing the risk of false alarms and ensuring consistent operation. Its process connection is threaded R 1-1/2 inch BSPT (EN 10226), and it supports process temperatures without the need for an isolator. With its compact size and rotatable enclosure, installation and wiring are both convenient and straightforward. Power supply options range from 19 to 230 V AC or 19 to 55 V DC, with one relay output (SPDT) for reliable switching. Approvals include CSA/FM Dust Ignition Proof and RCM certification, ensuring compliance with global standards.

Overview

The SITRANS LVS200 is specifically engineered to detect high, low, or demand levels of dry solids. It is also available in a liquid/solid interface version, capable of detecting settled solids within liquids, making it a versatile solution for challenging applications. Extensions are available up to 4 m, with customer-specified designs reaching up to 20,000 mm.

Benefits

• Resistant to heavy mechanical loads and vibration
• Effective even in low-density materials, with options down to 5 g/l
• Rotatable enclosure for ease of wiring and mounting
• Durable short fork option for compact installations
• Optional 4 to 20 mA output for buildup monitoring and preventive maintenance

Application

The LVS200 is widely applied in bulk solid storage and processing systems. Typical applications include bins, silos, hoppers, and feed pipes, with the capability to ignore liquid and detect solid material interfaces. Its design minimizes maintenance requirements and ensures reliable operation in dusty, abrasive, or sticky environments. A unique crystal excitation system allows the fork to vibrate continuously, and the relay changes state only when material presence is confirmed, ensuring dependable level detection.
