Equipment Compatibility and System Matching

This sensor matches perfectly with standard Bently Nevada 3300 XL extension cables. It feeds clean signals directly into the Bently Nevada 3500 Machinery Protection System. The probe monitors gas turbines, steam turbines, centrifugal compressors, and heavy industrial pumps. It tracks axial thrust position and radial vibration on fluid-film bearing surfaces perfectly.

Installation Guide

• Thread the probe housing into the 3/8-24 UNF reverse-mount bracket assembly carefully.
• Maintain a maximum thread engagement length of 0.563 inches to prevent mechanical damage.
• Torque the sensor case to standard engineering tolerances without exceeding the 330 N tensile limit.
• Route the triaxial cable away from high-voltage electrical lines to eliminate crosstalk noise.
• Ensure the internal Viton O-ring seats cleanly inside the housing to lock out moisture.

Commissioning & Maintenance Benefits

The Miniature ClickLoc coaxial connector allows rapid tool-free connection to your machine extension cables. Gold-plated brass contacts eliminate connection degradation and prevent signal loss over long maintenance intervals. Operators can verify loop integrity by reading the nominal 7.45-ohm DC resistance across the conductors. The durable polyphenylene sulfide tip material resists chemical breakdown during prolonged oil submersion cycles.

Frequently Asked Questions (FAQ)

Question: What is the length of this specific probe model?

Answer: This specific probe features a total length option of 0.5 meters (1.6 feet).

Question: Can I expose the probe tip to sub-zero industrial environments safely?

Answer: The probe operates down to -52°C, but avoid dropping below -34°C to protect the Viton pressure seal.

Question: How does the modification code affect the standard 3300 XL probe properties?

Answer: The MOD specification tailors electrical or mechanical configurations for specific industrial machine housings without degrading signal linearity.

Procurement and Selection Guide

Verify your machine casing thread before ordering the 330105 series probe sensor. This variant utilizes 3/8-24 UNF threads, which differ from metric mounting alternatives. Check your existing extension cable length to ensure a total system calibration length of 5 or 9 meters.
