Product Overview

The Bently Nevada 330851-02-000-080-50-00-05 is a rugged 3300 XL 25 mm proximity probe specifically engineered for maximum survivability in the harshest steam turbine Differential Expansion (DE) environments. This large-scale sensor is designed to replace legacy 7200 25mm and 35mm systems, offering superior accuracy and thermal resilience.

Proudly Made in the U.S.A., this probe features a robust M30x2 threaded case and a 5.0-meter total length, providing the extended range and durability required for large rotating machinery protection.

Engineered for Extremes

The 3300 XL 25 mm probe is built to endure. Its PEEK tip and FluidLoc triaxial cable ensure signal integrity even when exposed to high-pressure steam and turbine oils. With a short-term temperature rating of +250 °C (482 °F), it provides a safety margin for unexpected thermal excursions, ensuring your critical machinery remains protected during peak loads.

Certifications & Compliance

This probe meets global standards for hazardous area installations, including ATEX/IECEx for Zone 0 and Zone 2, and Class I, Division 2 groups A, B, C, and D. It is also compliant with maritime standards (ABS) and the RoHS Directive, making it suitable for both offshore and land-based power generation applications.

Technical FAQs

Q1: Can this probe replace my existing 7200 series 25mm probe?

A1: Yes, the 330851 series is specifically designed as a physical and functional replacement for legacy 7200 25mm and 35mm transducer systems.

Q2: What is the benefit of the FluidLoc cable?

A2: The PFA-insulated FluidLoc cable prevents moisture and oil from wicking through the cable, which is essential for maintaining accuracy in steam-saturated environments.

Q3: How should I gap this probe?

A3: Proper gapping depends on your specific Proximitor sensor calibration. Given its 25mm diameter, it is intended for large-scale displacement measurements like turbine differential expansion.
