Quick Detail

Description

The 330101-00-66-10-02-CN is a precision-engineered 3300 XL 8 mm Proximity Probe, representing the forefront of eddy current sensing technology from Bently Nevada. This non-contacting transducer is fundamental to modern machinery condition monitoring, generating an output voltage that is precisely and linearly proportional to the distance between its sensitive tip and a conductive target surface. This enables the probe to perform both dynamic vibration measurements and static position (displacement) monitoring with exceptional accuracy, making it an indispensable sensor for the health assessment and protection of high-value rotating assets such as turbines, compressors, and large pumps.

This specific model, identified by its unique option code, features a tailored physical configuration with an overall case length of 6.6 inches and a minimum unthreaded length of 0 inches, designed for specific mounting depth requirements in machinery casings and brackets. It is equipped with a reliable miniature coaxial ClickLoc connector and a standard cable with a total length of 1.0 meter (3.3 feet), providing a ready-to-install sensor solution. The probe's construction utilizes a probe tip material of Polyphenylene Sulfide (PPS) for wear resistance and electrical insulation, housed within a robust probe case material of AISI 301 or 304 stainless steel, ensuring durability in corrosive and high-temperature environments.

Applications

This 3300 XL 8 mm Proximity Probe is primarily deployed for continuous online monitoring of critical turbomachinery in power generation and oil & gas sectors. It is used to measure radial vibration and axial thrust position on steam turbines, gas turbines, and centrifugal compressors. Its robust construction and wide operating temperature range allow it to perform reliably inside hot bearing housings and under high-pressure conditions, providing the essential data needed to detect rotor instability, misalignment, and impending bearing failures before they cause catastrophic damage and unplanned downtime.

The probe serves as a fundamental sensor for Keyphasor reference and speed measurement in various industrial rotating equipment. Installed near a keyway or reflective spot on a shaft, it generates a once-per-revolution timing pulse. This signal is critical for advanced diagnostic techniques such as orbit analysis, phase measurement, and transient analysis during machine startup and shutdown. Its precise output and compatibility with monitoring systems make it indispensable for balancing operations and understanding the dynamic behavior of fans, pumps, and motors in manufacturing and processing plants.

Due to its comprehensive agency approvals (CSA, ATEX, IECEx), this probe is extensively used in classified hazardous areas within petrochemical refineries, chemical plants, and offshore platforms. It monitors the vibration and position of pumps, mixers, and blowers operating in potentially explosive atmospheres. The probe's durable stainless steel case and PPS tip material resist corrosion from process chemicals, ensuring long-term reliability and safety compliance in these demanding environments where equipment failure can have severe consequences.

Specifications

Competitive Advantage

1.Certified Robustness for Hazardous and Extreme Environments

The 330101-00-66-10-02-CN offers a significant safety and compliance advantage with its full suite of international agency approvals (CSA, ATEX, IECEx). This pre-certification facilitates its specification and installation in explosive atmospheres and demanding industrial sites globally, reducing project risk and approval time. Combined with its wide operating temperature range and corrosion-resistant stainless steel case, it delivers unwavering reliability where other sensors may fail, ensuring continuous protection of critical assets in the most challenging sectors like oil & gas and chemical processing.

2.Precision Engineering for Uncompromising Measurement Accuracy

This probe is engineered to provide exceptional measurement fidelity. Its defined linear range of 2 mm and optimized electrical characteristics ensure a stable, repeatable output voltage directly proportional to gap distance. The use of advanced materials like PPS for the probe tip ensures consistent performance and longevity. This high level of accuracy is crucial for detecting subtle changes in machine vibration and position, enabling early fault diagnosis and providing trustworthy data for effective predictive maintenance strategies and reliable machinery protection.

3.Seamless System Integration and Legacy Compatibility

A key operational advantage is the probe's complete interchangeability within the Bently Nevada 3300 XL ecosystem and its backward compatibility with non-XL 3300 series components. This "plug-and-play" design allows for easy replacement, system expansion, or upgrades without requiring time-consuming recalibration. The inclusion of a miniature coaxial ClickLoc connector simplifies installation and ensures a secure connection. This compatibility protects existing investments in monitoring infrastructure while providing access to the enhanced performance of the XL platform, simplifying inventory management and reducing total lifecycle costs.
