Functional Features

• Dual-Channel Signal Processing: Supports two independent Proximitor® sensor inputs, enabling simultaneous monitoring of two machinery parameters (e.g., radial vibration on opposite shaft ends).
• High-Precision Measurement: 16-bit ADC resolution and ±0.1% full-scale accuracy ensure reliable data capture for critical machinery health assessment.
• Sensor Excitation: Provides 18 VDC excitation voltage to connected Proximitor® sensors, eliminating the need for external power supplies.
• Redundant Configuration Support: Can be paired with additional 143729-01 modules in 2-out-of-2 or 3-vote redundant setups, meeting safety requirements for mission-critical applications.
• Seamless System Integration: Communicates via 3500 rack backplane and integrates with Bently Nevada’s System 1 software for real-time monitoring, data logging, and fault diagnosis.
• Built-In Diagnostics: Features self-test functionality and status LEDs (OK, Fault, Bypass) for quick visual verification of module and sensor health, simplifying troubleshooting.
• Harsh Environment Resilience: Withstands wide temperature ranges, vibration, and shock, ensuring consistent performance in industrial settings such as power plants or refineries.
• Configurable Measurement Ranges: Adapts to different sensor types via software configuration, supporting diverse monitoring needs across rotating machinery.

Application Scenarios

• Power Generation: Monitors shaft displacement and radial vibration in steam turbines, gas turbines, and generators, preventing rotor damage and ensuring stable power output.
• Oil and Gas Industry: Used in upstream (drilling rig motors), midstream (pipeline compressors), and downstream (refinery pumps) operations to protect critical rotating equipment.
• Chemical Processing: Tracks agitator shaft position and reactor mixer vibration in corrosive environments, complying with strict safety and process standards.
• Steel Manufacturing: Monitors roll neck displacement in hot rolling mills and fan vibration in blast furnaces, supporting continuous production and reducing downtime.
• Marine Engineering: Protects propulsion system shafts and auxiliary pump bearings on ships and offshore platforms, withstanding saltwater corrosion and marine vibration.
• Heavy Industry: Supports condition monitoring of mining crushers, cement mill drives, and metallurgical gearboxes, ensuring reliability in high-demand, dusty environments.
• Aerospace & Defense: Used in ground-based gas turbine test facilities to measure shaft vibration and displacement during engine performance validation.
