BENTLY 146031-01

Product introduction

The 146031-01 from Bently Nevada is a high-performance 16-channel signal termination panel, designed to serve as a critical interface between field sensors and machinery monitoring systems in industrial environments. As an essential component in Bently Nevada’s system architecture, this termination panel provides organized, protected connectivity for vibration and position sensors, ensuring reliable signal transmission while simplifying installation and maintenance.

Engineered to streamline sensor integration, the 146031-01 consolidates connections from proximity probes, velocity sensors, and accelerometers—such as the 330130-040-01-00 proximity probe—into a centralized panel. Its isolated channels prevent signal interference and ground loops, preserving measurement integrity in electrically noisy industrial settings. When paired with compatible monitoring systems and sensors, it forms a robust infrastructure for machinery health monitoring, enabling efficient data collection and analysis in power generation, petrochemical, and manufacturing facilities.

Core advantages and technical highlights

Enhanced signal isolation: The 146031-01 features 2.5kVrms isolation between channels and from channels to ground, providing superior protection against electrical noise, transient voltages, and ground loops that can corrupt sensor signals. This isolation ensures measurement accuracy even in environments with multiple connected systems and high electromagnetic interference (EMI), such as near large motors or variable frequency drives.

Centralized connectivity: With 16 isolated channels, the 146031-01 consolidates sensor connections into a single panel, eliminating the need for scattered junction boxes and reducing cable clutter. This centralized approach simplifies system design, eases troubleshooting, and provides a clear wiring infrastructure that reduces installation time and errors. Each channel is clearly labeled for easy identification and maintenance.

Industrial-grade durability: Constructed with rugged materials and robust connectors, the 146031-01 withstands harsh industrial environments, including temperature extremes (-40°C to 70°C), humidity, and vibration. The MIL-C-5015 field connectors provide secure, moisture-resistant connections for sensor cables, while the panel’s sturdy housing protects internal components from dust and physical damage.

Flexible system integration: The termination panel is designed to work seamlessly with Bently Nevada’s 3300 series sensors and 3500 monitoring systems, ensuring compatibility and optimal performance. Its terminal block system side connections simplify integration with various monitoring equipment, providing flexibility for system expansions or upgrades. The panel’s modular design allows for easy scaling of monitoring capabilities as facility needs grow.

Typical application scenarios

In gas turbine power plants, the 146031-01 serves as the central connection point for vibration and position sensors monitoring turbine shafts, bearings, and auxiliary equipment. It consolidates signals from multiple 330130-040-01-00 proximity probes installed along the turbine train, providing isolated connections to the plant’s 3500 monitoring system. This centralized termination simplifies maintenance during outages and ensures reliable signal transmission in the electrically noisy power generation environment.

Within petrochemical refineries, the 146031-01 is installed in hazardous area control rooms, terminating signals from sensors monitoring compressor trains, pumps, and fans. Its ATEX Zone 2 certification ensures safe operation in potentially explosive environments, while the enhanced isolation protects against electrical interference from nearby processing equipment. The panel’s organized layout facilitates quick sensor swapping during maintenance without disrupting entire monitoring loops.

In large manufacturing facilities, the 146031-01 provides centralized sensor termination for production line machinery, including motors, gearboxes, and conveyors. It connects to a variety of sensors—from proximity probes to accelerometers—consolidating their signals for transmission to plant-wide monitoring systems. This approach simplifies the integration of machinery health data into production management systems, enabling coordinated maintenance scheduling and maximizing equipment uptime.
