Bently Nevada 330876-02-10-00-00 3300 XL 50mm Proximity Probe

Quick Overview

The 330876-02-10-01-00 is a specialized 3300 XL 50 mm Proximity Probe, the largest in the Bently Nevada eddy-current transducer family. This "Extended Range" probe is specifically engineered for measurements that exceed the capacity of standard 8 mm or 25 mm systems. With its massive 50 mm (2.0 inch) tip diameter, it is capable of a linear measurement range up to 27.9 mm (1100 mils).

Key Features

• Extended Range Displacement: Capable of measuring massive shifts in machinery position, specifically designed for differential expansion (DE) applications in large power generation turbines.

• FluidLoc® Cable Technology: The Option 01 cable is specifically treated to prevent "wicking," ensuring that oils or high-temperature fluids cannot travel through the cable into the Proximitor or junction box.

• Stainless Steel Armor: Features a flexible, crush-resistant stainless steel protective sleeve (armor) over the cable, providing superior mechanical protection in exposed high-traffic areas.

• Large Diameter Sensing: The 50 mm tip creates a larger magnetic field, allowing it to accurately track targets that may have significant surface irregularities or cross-axis movement.

• High-Temperature Resilience: Built to withstand the extreme thermal cycling found near steam turbine casings, ensuring long-term signal stability without drift.

• Rugged Metric Housing: The M14x1.5 threaded case provides a heavy-duty mounting interface suitable for thick-walled machine housings and industrial brackets.
