Core Features & Technical Advantages

Non-Contact Eddy Current Measurement
Employs electromagnetic induction principles to monitor shaft displacement without physical contact, eliminating wear-related failures and enabling continuous operation in high-speed rotating equipment up to 10 kHz frequency response.

Factory-Calibrated 5-Meter Extension Cable
Pre-calibrated system length reduces commissioning time and ensures measurement accuracy across the entire signal path. The 5-meter configuration provides installation flexibility for equipment with challenging probe mounting locations.

Wide Operating Temperature Range
Functions reliably from -30°C to +100°C (-22°F to +212°F), accommodating extreme ambient conditions in steam turbines, gas compressors, and outdoor installations without performance degradation.

High Signal-to-Noise Ratio
Delivers -2 to -18 VDC linear output with 200 mV/mil (7.87 mV/μm) scale factor, providing clean signals for accurate data acquisition even in electrically noisy industrial environments with VFDs and high-power switchgear.

Rugged Epoxy-Encapsulated Construction
Sealed housing protects internal electronics from moisture, chemical exposure, and mechanical shock. TNC coaxial connector ensures secure, vibration-resistant signal transmission with minimal electromagnetic interference.

Plug-and-Play 3300 XL Ecosystem Integration
Direct compatibility with Bently Nevada 3300 XL monitor racks, proximity probes (330100/330105/330400 series), and Proximitor housings eliminates custom calibration requirements and accelerates system deployment.

Typical Application Scenarios

This Proximitor sensor excels in applications demanding continuous shaft position monitoring, vibration analysis, and machinery protection, particularly in:

Steam & Gas Turbine Monitoring
Measures radial vibration, axial thrust position, and differential expansion in power generation turbines. Detects rotor rubs, bearing wear, and thermal bowing before damage occurs, supporting condition-based maintenance strategies.

Centrifugal Compressor Protection
Monitors shaft displacement in multi-stage compressors handling natural gas, air, and process gases. Provides early warning of surge conditions, seal failures, and rotor instability in API 617/API 672 compliant installations.

Large Motor & Generator Surveillance
Tracks rotor eccentricity and bearing clearances in motors above 500 HP and generators in combined-cycle plants. Enables predictive maintenance by identifying misalignment, soft foot, and foundation issues.

Pump & Fan Vibration Analysis
Applied to critical boiler feed pumps, cooling water pumps, and induced draft fans where unplanned outages impact production. Detects cavitation, impeller imbalance, and coupling degradation through displacement trending.

Technical Specifications & Selection Guide

To facilitate engineering design and procurement, the following parameters define the 330197-10-50-05 sensor system:

Selection Considerations:
When specifying this sensor, evaluate total system length (probe + extension cable + monitor input cable), target material conductivity (ferrous vs. non-ferrous), mounting space constraints, and ambient temperature extremes. For applications requiring cable lengths beyond 5 meters or specialized probe configurations, consult with our application engineering team to ensure system linearity and calibration accuracy.

Technical support services include pre-installation system design review, commissioning assistance (remote or on-site depending on location), and troubleshooting guidance. Complete documentation package provided: calibration certificate, installation drawing, wiring diagram, and operation manual in PDF format for maintenance reference.

All units undergo factory acceptance testing per Bently Nevada quality procedures, including linearity verification, temperature cycling, and connector pull-force testing to ensure field reliability.

Frequently Asked Questions (FAQ)

Q: How does the 330197-10-50-05 Proximitor sensor interface with existing 3300 XL monitoring systems?
A: The sensor connects directly to 3300 XL Proximitor housings or monitor rack input modules via TNC coaxial cable. Verify that total system length (probe + extension + input cable) matches the factory calibration range specified in the 3300 XL system manual. No field recalibration required for standard configurations.

Q: What is the maximum number of sensors I can connect to a single monitoring rack?
A: This depends on your 3300 XL rack configuration. Standard 19-inch racks accommodate up to 16 channels (8 dual-input modules). For larger installations, multiple racks can be networked through communication gateways. Consult system capacity planning guides for power budget and I/O density.

Q: Can this sensor measure vibration on non-ferrous shafts like stainless steel or titanium?
A: Yes, but with reduced sensitivity. Eddy current sensors work best with ferrous targets (carbon steel, 4140 alloy). For non-ferrous materials, expect 30-50% scale factor reduction and potential linearity deviations. Consider using conductive target sleeves or alternative sensor technologies (accelerometers) for optimal performance.

Q: What environmental protection does the sensor housing provide?
A: The epoxy-encapsulated design offers IP65-equivalent protection against dust and water jets. Suitable for outdoor installations with proper cable gland sealing. Not submersible. For corrosive chemical environments, verify material compatibility or specify protective coatings.

Q: How do I verify sensor functionality during commissioning?
A: Use a Bently Nevada TK-3 test kit or equivalent gap measurement tool. With the probe installed at the target surface, verify output voltage changes linearly from approximately -2 VDC (maximum gap) to -18 VDC (minimum gap) as you adjust probe-to-target distance. Deviation beyond ±10% indicates calibration issues or system length mismatch.

Q: Does the 5-meter cable length include the probe cable or is it additional?
A: The 5-meter specification refers to the extension cable only, installed between the proximity probe and the Proximitor housing/monitor input. Total system length = probe cable + 5m extension + housing-to-monitor cable. Always verify against 3300 XL system length specifications (typically 5m or 9m total).
