ALK Electrolyzer Bolt Preload Monitoring System (BoltGuard)

The BoltGuard system is a state-of-the-art, long-term bolt preload monitoring solution designed for ALK hydrogen electrolyzers. By continuously tracking bolt stress variations, it provides early warnings for critical mechanical and structural issues, such as:

· Gasket creep leading to sealing degradation

· Disc spring lock-up affecting load distribution

· Bolt stress relaxation reducing structural integrity

· Alkaline electrolyte leakage posing operational and safety risks

Key Advantages of BoltGuard

✅ Optimized for Large Bolts – Designed to ensure stable, high-fidelity signal quality, even in demanding industrial environments.

✅ Certified for Hydrogen Electrolyzers – Compliant with Ex II CT6 explosion-proof standards, making it suitable for hazardous hydrogen environments.

✅ Multi-Channel Monitoring – Capable of simultaneously monitoring up to 10 bolts, providing a comprehensive structural assessment in real time.

✅ Ultrasonic Non-Intrusive Technology – Utilizes advanced ultrasonic sensing for bolt preload assessment, ensuring zero impact on existing mechanical structures.

✅ Wireless & Battery-Powered – A fully autonomous system that enables flexible installation without the need for external power sources, reducing wiring complexity and enhancing adaptability.

By implementing BoltGuard, operators of ALK electrolyzers can achieve proactive maintenance, minimize unplanned downtime, and enhance system safety and efficiency.
