BENTLY 330101-00-25-20-12-05 3300 XL Proximity Probe
Product Overview
The BENTLY 330101-00-25-20-12-05 is a high-precision 3300 XL Proximity Probe engineered for continuous monitoring of shaft displacement and vibration in critical rotating machinery. As a core component of Bently Nevada’s 3300 Series Machinery Protection System, this probe converts mechanical movements into electrical signals, enabling real-time analysis of shaft position, vibration amplitude, and dynamic behavior in turbines, compressors, and generators. The 330101-00-25-20-12-05 integrates seamlessly with 3300 Series monitors (e.g., 3300/42M) and 3500 Series rack systems, delivering reliable measurements to support predictive maintenance across industries such as oil & gas, power generation, and manufacturing.
Featuring a rugged stainless-steel construction, the BENTLY 330101-00-25-20-12-05 includes an 8 mm diameter probe tip designed for harsh industrial environments. The probe offers a measurement range of 0–250 mils (0–6.35 mm) with ±0.5% linearity, ensuring precise detection of shaft movements. Its hermetically sealed enclosure (IP65-rated) and corrosion-resistant materials protect against dust, moisture, and chemical exposure, while the wide temperature range (-40°C to +177°C) makes it suitable for high-temperature applications. The probe supports standard 2-wire installations, simplifying integration with existing monitoring networks and reducing installation complexity.
In automation ecosystems, the 330101-00-25-20-12-05 serves as a front-end sensor for machinery protection systems, feeding real-time displacement data to monitoring modules for trend analysis and alarm activation. Its compatibility with industry standards (e.g., API 670) ensures compliance with safety regulations, while low-output impedance minimizes electromagnetic interference. By providing actionable insights into shaft health, this probe helps reduce unplanned downtime and extend equipment lifespan in mission-critical operations.
