Advantages and Features

1. Double-Shielded EMI/RFI Immunity

   The BENTLY 288055-01 employs a foil-and-braid double-shielded design that eliminates signal interference from high-voltage motors, variable frequency drives (VFDs), and other industrial equipment. This shielding ensures that Keyphasor signals remain noise-free, enabling precise rotor phase and speed measurements critical for detecting shaft imbalance, misalignment, and torsional vibration.

2. Rugged Industrial Durability

   With an abrasion-resistant outer jacket and IP67-rated connectors, the BENTLY 288055-01 withstands harsh operating conditions, including exposure to oil, grease, chemical vapors, and mechanical abrasion common in power generation, oil & gas, and petrochemical facilities. Its wide temperature range (-40°C to +125°C) supports deployment in cryogenic LNG compressors and high-temperature steam turbine environments.

3. Seamless Compatibility with Bently Nevada Systems

   Designed exclusively for Bently Nevada’s 3300 Series Keyphasor probes and proximitors, the BENTLY 288055-01 ensures plug-and-play integration without signal degradation or compatibility issues. This native compatibility reduces installation time by up to 25% and eliminates the risk of signal loss that can occur with generic cables.

4. Corrosion-Resistant Connector Design

   The cable’s gold-plated connector contacts and corrosion-resistant housing prevent oxidation and signal degradation over time, extending service life to over 10 years in harsh, humid environments. This durability reduces maintenance replacement costs and ensures consistent signal performance for long-term condition monitoring.

5. Flexible Installation & Maintenance

   The BENTLY 288055-01’s flexible cable construction enables routing in tight control cabinet spaces and around rotating machinery, while its color-coded connectors simplify field identification and troubleshooting. The cable is also compatible with Bently Nevada’s signal test tools, enabling quick verification of signal integrity during maintenance checks.

Application Cases in Application Fields

1. Steam Turbine Speed & Phase Monitoring (Power Generation)

   A 1,200 MW coal-fired power plant deploys the BENTLY 288055-01 to connect Keyphasor probes to proximitors in its high-pressure steam turbine system. The cable’s double-shielded design eliminates EMI from nearby generator equipment, enabling accurate phase reference measurements that detect early-stage shaft misalignment. This proactive detection allows maintenance teams to schedule repairs during a planned outage, avoiding an estimated $2.8 million in unplanned downtime.

2. Offshore Compressor Rotor Position Sensing (Oil & Gas)

   An offshore oil platform uses the BENTLY 288055-01 to transmit Keyphasor signals from compressor rotor probes to on-board monitoring systems. The cable’s IP67 connectors and corrosion-resistant design withstand salt spray and humid conditions, ensuring reliable operation in the marine environment. Accurate position data helps prevent compressor surge events, reducing equipment damage and ensuring continuous gas production.

3. Industrial Gas Turbine Condition Monitoring (Petrochemical)

   A petrochemical refinery integrates the BENTLY 288055-01 into its gas turbine condition monitoring system, supporting speed and phase measurements for predictive maintenance. The cable’s high-temperature tolerance (-40°C to +125°C) ensures stable performance in the refinery’s extreme ambient conditions, while its low-noise transmission enables precise detection of blade tip clearance changes and rotor imbalance.

4. Wind Turbine Gearbox Health Monitoring (Renewable Energy)

   A utility-scale wind farm uses the BENTLY 288055-01 to connect Keyphasor probes to proximitors in wind turbine gearboxes. The cable’s rugged jacket resists abrasion from wind turbine tower vibrations, and its EMI shielding eliminates interference from the turbine’s power electronics. Accurate speed data helps optimize gearbox lubrication schedules, extending gearbox service life by 15%.

Selection Suggestions and Precautions

Selection Suggestions

1. Prioritize for Bently Nevada 3300 Series Systems

   Choose the BENTLY 288055-01 for use with Bently Nevada 3300 XL Keyphasor probes and proximitors to ensure optimal signal integrity and plug-and-play compatibility.

2. Opt for Harsh Environment Deployments

   Select the cable for applications in extreme temperatures, humid or corrosive environments, or high-EMI industrial settings where generic cables would fail or degrade signal quality.

3. Match with Turbomachinery Condition Monitoring

   Pair the BENTLY 288055-01 with turbine, compressor, or generator condition monitoring systems to support accurate speed, position, and phase reference measurements for predictive maintenance.

Precautions

1. Connector Compatibility Check

   Ensure the BENTLY 288055-01 is paired with Bently Nevada DIN 43650 A-type Keyphasor probes and proximitors; mismatched connectors will cause signal loss or equipment damage.

2. Cable Routing Guidelines

   Avoid routing the BENTLY 288055-01 parallel to high-voltage power cables or VFD output cables; maintain a minimum 30 cm separation to minimize EMI interference.

3. Installation Torque Specifications

   Tighten connector nuts to Bently Nevada’s recommended torque (0.8–1.0 N·m) during installation; over-tightening will damage connector threads, while under-tightening will cause signal leakage.

4. Storage Conditions

   Store spare BENTLY 288055-01 cable assemblies in a dry, temperature-controlled environment (0°C to +30°C) with relative humidity below 70%, and avoid bending cables beyond their minimum bend radius (10× cable diameter).
