🌐 Overview
The Bently Nevada 3300 XL 11mm Proximity Probe is designed for accurate, stable, and long-term vibration and shaft position monitoring in critical rotating machinery such as turbines, compressors, and pumps. Its robust construction and advanced design make it ideal for harsh industrial environments, delivering reliable performance in the most demanding applications.
This model (part number 330701-00-24-10-12-05) features a PPS probe tip, 304 stainless steel housing, and FluidLoc™ cable technology that prevents oil leakage. Combined with the ClickLoc™ connector, it ensures a secure, leak-free, and durable connection.
⚙️ Key Features
- 1/2-20 UNF threaded case – allows quick and secure installation.
- 1.0-meter triaxial cable with miniature coaxial ClickLoc connector for consistent signal quality.
- Wide temperature range: operates from –51°C to +177°C (–60°F to +350°F).
- 75 Ω FEP-insulated cable ensures signal integrity over long distances.
- Multiple agency approvals (suffix 05) for global compliance.
- Compatible with all Bently Nevada 3300 XL monitoring systems.
🧠 Why Choose the 11mm Probe?
Compared to the 8mm variant, the 11mm probe offers an extended linear range and greater immunity to oil contamination, making it ideal for large-shaft or high-amplitude vibration monitoring. It’s widely adopted in industries such as:
- Power generation
- Oil and gas
- Petrochemical refining
- Heavy industrial machinery
