Flexible Configuration: Software-based IP address and network parameter setup via user interface.

Key Applications:

Energy Sector: Monitoring turbines, generators, and transformers in power plants and wind farms to detect early faults and prevent unplanned downtime.
Oil & Gas: Vibration analysis of centrifugal compressors, pumps, and rotating equipment to enhance reliability.
Manufacturing: Predictive maintenance of motors, gearboxes, and production line machinery.
Aerospace: Structural health monitoring of aircraft engines and components.
Chemical Industry: Stability monitoring of reactors, pumps, and process equipment.
Rail Transport: Vibration tracking of locomotives, rolling stock, and track systems.
Marine Engineering: Condition monitoring of offshore platforms, ships, and marine propulsion systems.

Industry Compliance:

Meets API 670 standards for mechanical protection systems.
Designed for harsh industrial environments with robust temperature and humidity tolerance.

Integration with 3500 System:

Works exclusively with Bently Nevada 3500 series monitors (e.g., 3500/40M Proximitor® Monitor) to process vibration and position signals.
Supports synchronization with 3500/50M Tachometer Module for phase reference and speed measurement.
Enables alarm management and trend analysis via 3500 Rack Configuration Software.

Maintenance & Reliability:

Minimal routine maintenance required; periodic checks for secure connections and module stability recommended.
Diagnostic LEDs on the module indicate operational status and fault conditions.
One-year warranty covering defects in materials or workmanship (non-human-induced failures).
