Part Overview and Configuration Breakdown

The 330876-01-10-01-00 represents a heavy-duty, large-format 50 mm proximity transducer engineered specifically for extreme thermal environments within the 3300 XL series by Bently Nevada. Built to survive harsh steam turbine drive-end (DE) environments, this model integrates dual front-and-rear seals with armored high-temperature cabling. Below is the structured breakdown of its individual part number configuration:

Technical Specifications Matrix

Global PLC Spare HUB's Insight

• Field Engineering Note: During a high-temperature overhaul on a large utility steam turbine drive-end bearing, our engineering crew deployed the 330876-01-10-01-00 to monitor axial thrust and thermal expansion. Standard 8mm probes experience severe degradation under continuous 180°C steam wash environments, whereas the dual-sealed structure and specialized FluidLoc armor of this 50mm model completely eliminated moisture ingress and signal drift.
• Installation Practice: Technicians must utilize the disposable connector protector installation tool provided in the package during physical routing through tight casing clearances, ensuring the removable ClickLoc collar is carefully guided without scraping the PFA insulation.

Target Industrial Equipment and Application Scenarios

• Large utility steam turbine drive-end (DE) and non-drive-end (NDE) shaft axial position monitoring.
• Heavy industrial gas turbines operating under extreme casing temperatures exceeding standard sensor limits.
• Massive hydroelectric generator thrust bearings requiring high-stability gap measurements.
• High-pressure boiler feed pumps subjected to intense ambient thermal radiation.

Advanced Diagnostic Capabilities

• Tracks gross rotor axial position changes caused by thermal growth and thrust bearing wear.
• Detects heavy mechanical distortion, rotor bowing, and structural shifts in massive turbine casings.
• Maintains high signal integrity in high-EMI environments through triaxial shielding and specialized ClickLoc connectivity.

Selection Guide and Model Comparison

Global PLC Spare HUB's Insight: When engineers select large-format proximity probes for high-temperature turbines, matching case threading styles and cable exit configurations ensures a proper fit in existing mounting ports. Review the technical comparison below to guide your replacement strategy:

• Target Part: 330876-01-10-01-00 features a 1/2-20 straight-exit thread configuration with a 1.0-meter armored cable, ideal for standard imperial-threaded casing penetrations.
• Alternative Option: For applications requiring metric installation dimensions and alternative threading configurations, evaluate the 330876-02-50-01-00, which utilizes alternative metric case options for specialized housing retrofits.

Logistics, Warranty, and Support

• Fulfillment Carriers: Rapid worldwide shipping via FedEx, UPS, and DHL.
• Processing Window: Guaranteed order dispatch within 24 to 48 hours of verification.
• Quality Assurance: Supplied brand new in original factory packaging, backed by an absolute 12-month factory warranty.

Frequently Asked Questions

Question

What primary mechanical protection does the FluidLoc cable offer on the 330876-01-10-01-00?

Answer

The FluidLoc design incorporates internal blocking barriers that prevent oil, steam condensate, and process fluids from wicking through the cable core into the electronics if the outer jacket is compromised.

Question

How long can the 330876-01-10-01-00 safely endure short-term thermal spikes?

Answer

It can withstand intermittent temperatures up to +250°C (+482°F) for periods under 24 hours without permanent calibration degradation.

Question

Why does the 330876-01-10-01-00 utilize a triaxial cable configuration instead of standard coaxial?

Answer

The triaxial layout provides superior noise immunity and precise signal isolation in high-temperature, high-vibration power generation settings.

Question

What is the maximum allowed thread engagement when mounting this 50 mm probe case?

Answer

The maximum length of thread engagement for the 1/2-20 thread profile is 0.750 inches to prevent housing deformation against internal shoulders.

Question

What steps ensure the ClickLoc connectors remain pristine during field pull-through?

Answer

Always install the factory-supplied connector protectors and use the disposable installation tool to shield pin contacts from dust and moisture during cable routing.
