| Introduction In industrial plants, rotating machinery is the lifeline. A turbine, pump, or compressor failing unexpectedly can halt production and cost thousands, even millions. Over the years, engineers have learned that proactive monitoring is the only way to avoid surprises. That’s where Bently Nevada comes in. Their 3300 XL Proximity Probe series has been a trusted tool in condition monitoring for decades, helping engineers keep critical machinery safe. From the compact 3300 5 mm Proximity Probe to the robust 3300 XL 11 mm Proximity Sensor, this family covers a wide spectrum of applications. Coupled with extension cables and Proximitor sensors, these probes provide a complete monitoring solution. 3300 XL Series: Proven Tools in Action What makes the 3300 XL series so reliable? It’s a combination of design, flexibility, and practical engineering. Take a look at the lineup:

The beauty of the system lies in modularity. Engineers can swap a probe or cable without recalibration, saving hours of downtime. It’s not just convenience—it’s a lifeline in plants where every minute counts.
Durability is another highlight. Stainless steel housings, hermetic seals, and ClickLoc connectors with gold plating make the probes rugged enough for harsh industrial environments. On a recent refinery project, the 3300 XL sensors withstood high temperatures, dust, and electromagnetic interference (EMI) without losing a single reading.
Why Engineers Choose the 3300 XL Series
From field experience, the 3300 XL series delivers benefits that go beyond specs on paper:
Longevity – These sensors often operate reliably for over 10 years, reducing replacement costs.
Accuracy – Non-contact eddy-current measurement ensures minimal wear and highly consistent readings.
Flexible Installation – Extension cables like the 3300 XL 5 mm or 8 mm cables make it easier to fit sensors in complex setups.
Versatility Across Industries – Whether it’s a turbine, compressor, or pump, the probes protect critical rotating machinery.
Ease of Maintenance – ClickLoc connectors and modular components allow for quick swaps, avoiding costly downtime.
Consider a case where a turbine’s axial vibration needed constant monitoring. Using a 3300 XL 11 mm Proximity Probe with the matching 11 mm extension cable and Proximitor sensor, engineers could detect subtle shaft movement early, preventing a potential shutdown. Real-world deployments like this illustrate why the 3300 XL remains an industry favorite, even in 2025 under Baker Hughes’ asset protection solutions.
Conclusion
From 5 mm to 11 mm, the Bently Nevada 3300 XL Proximity Probes are more than just sensors—they’re a trusted companion for engineers on the plant floor. Rugged, precise, and modular, these probes, paired with their extension cables and Proximitor sensors, form a system that keeps critical machinery running smoothly.
Whether it’s a small compressor or a large turbine, the 3300 XL series provides actionable insights, reduces unplanned downtime, and helps teams protect valuable equipment. For engineers who rely on precision and reliability, Bently Nevada continues to deliver solutions that make a real difference in the field.
