330877-040-37-00 Bently Nevada 3300 XL Cable New In Stock

Product Overview

The 330877-040-37-00 is a high-temperature Bently Nevada 3300 XL 50 mm Extension Cable engineered for severe turbomachinery environments. Field engineers use this triaxial line to bridge the gap between a 50 mm proximity sensor and a remote Proximitor unit, maintaining signal stability across high thermal zones.

Built with armored PFA insulation and FluidLoc liquid barrier technology, the 3300 XL Series extension cable prevents oil and moisture penetration through the line core. The flexible stainless steel armor provides robust physical protection against crushing and abrasion inside tight machine casing runs.

Global PLC Spare HUB's Insight

In turbine deck installations, standard extension cables frequently suffer signal attenuation due to oil soaking through the outer jacket. The 330877-040-37-00 addresses this common point of failure with its internal FluidLoc core blocking feature. When pairing this 4.0-meter cable with a 1.0-meter 50 mm probe, technicians achieve an exact 5.0-meter system length, eliminating phase error and calibration drift.

Configuration Breakdown

Technical Specifications

System Matching & Length Selection

• Always calculate system length: Probe Length + Extension Cable Length = Proximitor Sensor Rating.
• Pair this 4.0-meter cable with a 1.0-meter probe to match a standard 5.0-meter Proximitor unit.
• Avoid mismatching total length, as improper electrical lengths skew system sensitivity and voltage output.
• Ensure all ClickLoc coaxial connectors remain clean during installation using protective caps.

Target Applications & Machinery

• Differential expansion measurement loops on large power-generation steam turbines.
• Axial rotor position monitoring systems on heavy-duty gas turbines.
• Inter-housing sensor cabling across high-temperature casing penetrations.
• Turbomachinery monitoring chains subjected to oil mist and steam spray environments.

Diagnostic & Maintenance Value

• Prevents false vibration readings caused by cable degradation in thermal zones up to 200°C.
• Maintains constant loop resistance for precise peak-to-peak displacement measurements.
• Protects internal coaxial conductors against crushing during maintenance turnarounds.

Commercial Terms & Logistics

• Item Condition: 100% Original and Brand New in factory sealed box.
• Warranty Coverage: Includes full 12-Month factory warranty protection.
• Order Processing: Fast turnaround, dispatches within 24-48 hours.

Frequently Asked Questions

Q1: Can I use this extension cable with standard 8 mm probes?

A1: No, the 330877-040-37-00 cable is designed specifically for 3300 XL 50 mm series proximity systems and their matching Proximitors.

Q2: Why is cable length matching critical for eddy current systems?

A2: Eddy current systems depend on tuned electrical length; a mismatch alters system capacitance and ruins calibration accuracy.

Q3: How does the FluidLoc option prevent oil leakage?

A3: FluidLoc technology fills spaces inside the cable core, preventing oil or steam condensate from wicking along internal wire spaces.

Q4: What tools are required to secure ClickLoc connectors on this line?

A4: ClickLoc connectors join by hand; use disposable connector tools to keep mating faces free of grease during install.

Q5: Can I trim or splice this cable to adjust length in the field?

A5: Never cut or splice proximity extension cables, as altering physical length ruins system tuning and voids warranty.
