Description

Technical Overview

The Bently Nevada 330101-00-20-90-02-00 is a high-precision 3300 XL 8 mm proximity probe engineered for demanding industrial condition monitoring and machinery protection applications. Designed as a core component of the industry-standard 3300 XL vibration monitoring system, this probe delivers exceptional linearity, repeatability, and thermal stability—critical for accurate shaft displacement, eccentricity, and vibration measurements in rotating equipment such as turbines, compressors, motors, and generators. Its robust construction ensures reliable performance in harsh environments characterized by extreme temperatures, electromagnetic interference, and mechanical vibration.

Featuring an 8 mm diameter sensing tip, the probe offers an optimal balance between resolution and measurement range (typically ±2.0 mm), making it ideal for medium-to-large bearing housings and critical machinery where tight clearance tolerances and early fault detection are paramount. The probe integrates seamlessly with 3300 XL extension cables and monitors, supporting IEEE Std 1127–compliant signal conditioning and enabling real-time health assessment aligned with ISO 10816 and API 670 standards. Its hermetically sealed, stainless-steel housing and PTFE-insulated coaxial cable provide superior resistance to oil, moisture, and chemical exposure—ensuring long-term integrity in refinery, power generation, and petrochemical installations.

Key Features

• Precision 8 mm Sensing Tip: Optimized for high-resolution shaft displacement and vibration monitoring with ±1% linearity across full range.
• Rugged Industrial Design: Stainless-steel body and PTFE-insulated cable rated for continuous operation at –30°C to +120°C ambient temperatures.
