Product Overview

The Bently Nevada 330104-01-14-05-01-CN is a premium 8mm eddy current proximity probe part of the 3300 XL transducer family. This sensor is engineered for high-accuracy displacement monitoring, converting the physical gap between the sensor tip and a rotating shaft into a linear electrical signal. It serves as a critical component in Turbine Supervisory Instrumentation (TSI) for detecting radial vibration, axial thrust position, and rotational speed.

This "CN" designated module is specifically built to withstand the rigors of modern industrial processes. Compared to legacy monitoring equipment, the 330104-01-14-05-01-CN offers significantly improved chemical resistance and enhanced side-view performance. Its design ensures that even in tight installation clearances where side-wall interference might affect other sensors, this probe maintains a stable and accurate scale factor for machinery protection.

Key Technical Characteristics

• Interchangeable Architecture: Designed with the "Universal Match" feature, allowing the probe to be used with any 3300 XL Proximitor sensor and extension cable of the same system length without requiring recalibration.

• Backward Compatibility: Electrically and mechanically compatible with legacy 3300 RAM series components, providing a seamless and cost-effective upgrade path for existing monitoring racks.

• Superior Chemical Resistance: The probe body is constructed from advanced polyphenylene sulfide (PPS) or similar high-grade polymers, offering better protection against corrosive process fluids and industrial lubricants than older probe designs.

• Refined Signal Performance: Outperforms 3000-series sensors in side-view applications, ensuring that measurement accuracy is preserved when the probe is mounted close to housing walls or in small-diameter ports.

• API 670 Standard Compliance: Engineered to meet the stringent requirements of the American Petroleum Institute for mechanical configuration, linear range, and thermal stability in critical machinery protection.

• Ruggedized Construction: Despite its lightweight 0.06 kg profile, the probe is built for extreme durability in high-vibration and high-temperature environments.
