Quick Detail

Description

The 330101-00-48-50-02-05 3300 XL 8 mm Proximity Probe is a high-performance eddy current sensor engineered for advanced industrial automation, turbomachinery diagnostics, and continuous condition monitoring systems. Featuring a 4.8 in case length, a 5 m cable assembly, and 3/8-24 UNF threaded housing, the probe provides precise static shaft position and dynamic vibration measurements critical for predictive maintenance, machine protection, and closed-loop process optimization. With a 2 mm linear range, low supply sensitivity, and stable voltage-to-gap conversion, the 330101-00-48-50-02-05 enables accurate shaft displacement tracking across compressors, gas turbines, steam turbines, refinery pumps, and high-speed rotating equipment commonly deployed in oil & gas, refining, and energy production. CSA, ATEX, and IECEx approvals expand its use into hazardous industrial environments, aligning with API 670 requirements for accuracy, linearity, and temperature stability. For automation OEMs and end-users, the patented CableLoc and TipLoc structural reinforcements deliver enhanced retention force up to 330 N and increased durability under thermal and vibration stress. These performance characteristics make the 3300 XL probe a robust sensing element for distributed monitoring, digital twin modeling, and Industry 4.0 asset performance management.

Applications

Application 1 Gas Turbine Vibration and Shaft Position Control
The probe delivers real-time displacement feedback within a 2 mm linear envelope, enabling turbine protection systems to optimize trip thresholds, reducing forced outages by approximately 15 to 25 percent in continuous-duty power generation units.

Application 2 Oil & Gas Compressor Bearing Condition Monitoring
With CSA and ATEX certifications, the probe supports hazardous-area compressor enclosures for bearing film stability diagnostics, improving operational efficiency by 8 to 12 percent under fluctuating load cycles.

Application 3 Refinery Pump Predictive Maintenance
Continuous vibration and displacement measurement enables predictive alarming for cavitation, seal wear, and imbalance faults, reducing reactive maintenance incidents by up to 30 percent and extending MTBF intervals.

Application 4 Keyphasor Reference for Rotating Machinery Speed and Phase
The probe functions as a phase reference sensor for speed and angle tracking during transient start-up and load ramping, achieving ±0.1 percent measurement precision for turbomachinery synchronization.

Application 5 Industry 4.0 Distributed Monitoring and Digital Twin Integration
When interfaced with SCADA, DCS, or historian platforms, monitoring data enhances digital twin prediction accuracy and remote asset analytics, improving plant-wide reliability indices by 10 to 18 percent.

Specifications

Competitive Advantage

Competitive Advantage 1 Hazardous Zone Global Compliance
CSA, ATEX, and IECEx certifications allow deployment in Zone 1/2 areas unlike generic proximity sensors, reducing engineering approval cycles for EPCs and OEMs in petrochemical projects.

Competitive Advantage 2 Extended Mechanical Envelope for OEM Mounting Flexibility
The 4.8 in case geometry supports custom turbine skid and compressor housing configurations, providing greater integration flexibility compared to shorter probe variants.

Competitive Advantage 3 Thermal Stability for Harsh Industrial Environments
Operational tolerance from −52°C to +177°C exceeds typical industrial sensor limits, ensuring stable monitoring in elevated turbine compartment temperatures.

Competitive Advantage 4 Backward Compatibility Across 3300 Series
Interchangeability with legacy 3300 components simplifies retrofit programs, eliminating matched pair calibration and reducing commissioning labor and downtime.

Competitive Advantage 5 Reinforced Cable Architecture for Longevity
Patented CableLoc technology provides 330 N retention strength, while optional FluidLoc prevents oil ingress along cable interiors, cutting leakage-related failures by up to 40 percent in lubrication-dense machinery halls.
