Bently Nevada 330101-02-12-15-01-CN Proximity Probe – 3300 XL 8mm Series
When a critical rotating machine loses its vibration monitoring signal, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned downtime, and in worst cases, irreversible damage to turbines, compressors, or pumps worth millions of dollars. The Bently Nevada 330101-02-12-15-01-CN proximity probe is the front-line sensor that prevents exactly this scenario — delivering continuous, non-contact shaft position and vibration data to your condition monitoring system 24/7.
Within the 3300 XL 8mm Proximity Probe series — Bently Nevada’s gold standard for industrial machinery protection — the 330101-02-12-15-01-CN is configured for a 12-inch (300 mm) probe length with a 15-foot (4.5 m) integral cable and CN connector termination, making it the preferred choice for installations requiring extended reach in confined machine casings. Trusted by rotating equipment engineers across oil & gas, power generation, and petrochemical industries worldwide, this series is specified in API 670 machinery protection systems globally.

System Integration & Compatible Parts
The 330101-02-12-15-01-CN is designed to operate as part of the complete Bently Nevada 3300 XL proximity probe system. Compatible components include:
- Proximitor® Sensors (Drivers): 3300 XL series (e.g., 330180, 330181) — signal conditioning and power supply for the probe.
- Extension Cables: 330130 series — extend the probe-to-Proximitor distance up to 9 meters total system cable length.
- Monitoring Systems: Bently Nevada 3500 Series Machinery Protection System, System 1® condition monitoring software.
- Mounting Hardware: Standard 3300 XL probe holders and lock nuts for various casing configurations.
Always verify total system cable length (probe integral cable + extension cable) does not exceed the specified maximum for your Proximitor model to maintain calibration accuracy.

Frequently Asked Questions
Q: Is the 330101-02-12-15-01-CN a direct replacement for older 3300 series probes?
A: The 3300 XL series is the successor to the original 3300 series. While the XL probes offer improved performance, they are generally backward-compatible with 3300 Proximitor drivers. Always verify driver compatibility with your specific system configuration before installation.
Q: What does the “CN” suffix in the part number indicate?
A: The “CN” designates the connector type — a coaxial CN connector at the cable termination end. This is the standard termination for most 3300 XL probe installations connecting to extension cables or directly to Proximitor sensors.
Q: Can this probe be used on non-steel target materials?
A: Yes, but a correction factor must be applied. The standard calibration is for AISI 4140 steel. For other materials (stainless steel, titanium, Inconel, etc.), Bently Nevada provides material correction factors to maintain measurement accuracy.
Q: What is the minimum order quantity?
A: We supply from single units to bulk orders. Contact us with your quantity requirement for the best pricing.
Q: Do you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, certificate of conformance, and can assist with other documentation requirements for your country’s import regulations.
Q: How long does shipping take?
A: Express courier (DHL/FedEx) typically delivers within 3–7 business days internationally. Sea freight and economy options are available for larger orders. Lead time depends on stock availability — confirmed at time of quotation.
