Function Features

• Reverse Mount & Space Efficiency: Optimized design enables installation in tight machinery layouts where standard probes cannot fit, expanding application flexibility.
• Precision Dual-Parameter Measurement: Delivers 1μm sensitivity and accurate detection of both static position/axial displacement and dynamic vibration/speed, supporting comprehensive machinery health assessment.
• Non-Contact Operation: Eliminates physical contact with moving components, minimizing maintenance needs and extending both the probe’s lifespan and the integrity of monitored machinery.
• Harsh Environment Resilience: IP66/IP67/IP69K ratings, high-grade materials, and gold-plated connectors provide resistance to dust, moisture, corrosion, and extreme temperatures (-40°C to +100°C).
• Rapid Response & Reliability: Sub-50ms response time ensures real-time data capture, while an MTBF exceeding 1,000,000 hours guarantees long-term operational dependability.
• Seamless Integration: Click Loc connectors enable tool-free, finger-tight installation, and compatibility with 3300 series systems allows easy integration into existing monitoring networks without bench calibration.
• Compliant Design: Meets API 670, CE, and ROHS standards, ensuring regulatory adherence and safety in global industrial applications.

Application Scenarios

• Power Generation: Monitors steam turbines, gas turbines, and generators, tracking shaft vibration, axial displacement, and keyphasor to maintain stable power output and prevent critical failures.
• Oil & Gas Industry: Deployed in compressors, pipeline pumps, and drilling rigs, withstanding corrosive environments while measuring vibration and speed to support predictive maintenance.
• Petrochemical & Chemical Processing: Used for condition monitoring of mixers, centrifugal pumps, and reactors, detecting subtle machinery changes to avoid unplanned downtime.
• Heavy Manufacturing: Integrates into steel mill rolling machines, cement plant fans, and automotive production line equipment, monitoring rotating components in dust-intensive and high-temperature settings.
• Industrial Automation: Connects to Bently Nevada 3500 series modules (3500/25, 3500/40, 3500/42M) and 2300/20 dual-channel monitors, forming a complete vibration and position monitoring system.
• Space-Constrained Installations: Ideal for machinery with limited mounting space, such as small-bore pumps and compact gearboxes, where reverse mount design provides compatibility.
