Unmatched Advantages for Bulk Solid Handling

1. Intelligent Design for Harsh Environments

The FTM50-3GG2A2A52AA features a rugged tuning fork design that ignores external vibrations and buildup. Unlike capacitive or conductive sensors, the vibrating fork only responds to changes in material coverage, ensuring that false signals from material sticking to the sensor are virtually eliminated .

2. True Maintenance-Free Operation

With no mechanical moving parts, there is nothing to wear out or jam. This design drastically reduces downtime and maintenance costs compared to electromechanical paddle switches, guaranteeing a long service life even under heavy load conditions .

3. Versatile Application Range

This specific model configuration is optimized for fine-grained solids, but its robust construction allows it to handle a wide spectrum of media densities and particle sizes. The option for PTFE or ETFE coatings on the fork protects against corrosion and material adhesion .

4. Global Certifications and Safety

Safety is paramount in industrial processing. The FTM50 series holds international explosion-proof certifications, including ATEX and IECEx, making it suitable for use in explosive atmospheres containing combustible dusts or gases . Its certification to SIL2 ensures it meets the highest safety integrity levels for risk reduction applications .

5. Flexible Integration

The FTM50-3GG2A2A52AA supports various electronic inserts (such as NAMUR, Relay, or PFM) to interface seamlessly with virtually any process control system or PLC .

Why Choose the Endress+Hauser FTM50?

Since pioneering vibrating level switches in 1967, Endress+Hauser has remained the market leader in solids detection . The FTM50-3GG2A2A52AA embodies this legacy, offering unmatched reliability for overfill protection and dry-run prevention. By choosing this instrument, you invest in a device that delivers accurate readings regardless of dust generation, flow against the rod, or changing material properties.
