Function Features

• Reverse Mount Design: Facilitates installation in confined spaces and complex machinery layouts where standard probes lack compatibility, expanding application flexibility.
• Ultra-Precision Measurement: Delivers 0.001 mm resolution and 1 μm sensitivity, detecting minute changes in vibration and displacement to enable early fault identification.
• Wide Temperature Adaptability: Operates reliably across extreme temperature ranges, from cryogenic -52 °C to high-heat +260 °C (cable and connector), suiting diverse industrial environments.
• Hazardous Environment Compliance: Certified with CSA, ATEX, and IECEx approvals, ensuring safe and compliant operation in explosive or high-risk industrial settings.
• Robust Durability: Stainless steel housing, PPS probe tip, and Viton® sealing provide resistance to corrosion, chemical exposure, and mechanical wear, ensuring long-term reliability.
• Secure Signal Transmission: Gold-plated connector enhances electrical conductivity and corrosion resistance, guaranteeing stable, accurate data transfer even in harsh conditions.
• Non-Contact Operation: Eliminates physical contact with moving components, reducing maintenance needs, preventing equipment wear, and ensuring uninterrupted monitoring.
• System Compatibility: Seamlessly integrates with Bently Nevada 3500 monitoring modules and other industrial automation systems, supporting streamlined data integration and analysis.
• Enhanced Mechanical Stability: Tip loc molding strengthens the bond between probe tip and body, while cable loc design ensures high pull strength, preventing damage during installation or operation.
