Proximity Probes | 3300 XL 25 mm | Bently Nevada | 330851-02-000-050-90-01-00

Overview

Engineered by Bently Nevada, the 3300XL 25mm Proximity Probe (Product No. 330851-02-000-050-90-01-00) replaces legacy 25mm and 35mm proximity probes across industrial systems. Built for harsh environments like steam turbines, it withstands continuous temperatures up to 200°C (392°F) and short-term exposure to 250°C (482°F). The probe features a PEEK tip for durability and an AISI 304 stainless steel case for corrosion resistance. Additionally, its 75Ω triaxial FluidLoc cable ensures reliable signal transmission in high-temperature, high-vibration settings.
