Description

The Bently Nevada 330101-36-80-10-02-00 is an unarmored 8 mm proximity probe from the industry-proven 3300 XL series. This specific configuration features a 3.6-inch unthreaded length, an 8.0-inch overall case length, a 1.0-meter (3.3-foot) total cable length, and a standard coaxial ClickLoc connector. It is engineered for industrial installations where standard machinery protection is needed without the requirement for hazardous area agency approvals.

This non-contact sensor operates on the eddy-current displacement principle, measuring shaft vibration and axial position on high-speed rotating machinery. As a fundamental component of the 3300 XL monitoring chain, it works in tandem with a 3300 XL Proximitor sensor and extension cable to deliver highly linear, precise displacement data to modern machinery protection systems like the Bently Nevada 3500 rack. The unarmored design offers simplified routing and a lighter profile for applications with external protective conduit systems.

Features

• Rugged polyphenylene sulfide (PPS) probe tip ensures chemical and temperature resilience in machinery interiors.
• Constructed with an AISI 303/304 stainless steel threaded body for superior corrosion resistance and high mechanical durability.
• Equipped with a gold-plated miniature coaxial ClickLoc connector for reliable, low-noise connection to extension cables.
• FEP triaxial cable insulation maintains electrical performance across a wide operating temperature range.
• Optimized for direct, permanent mounting on machine housings, bearing caps, and internal brackets.

Applications

• Shaft dynamic vibration and axial position monitoring in steam and gas turbines.
• Rotor position displacement tracking in heavy duty compressors, gearboxes, and pumps.
• Bearing oil film clearance and expansion measurements on critical turbomachinery.
• Continuous condition monitoring and machinery protection in power generation, petrochemical, and refining plants.

Installation Guidelines

• Maintain appropriate probe gap per system calibration requirements (typically 1.27 mm or 50 mils nominal gap).
• Ensure the minimum bend radius of 25.4 mm (1.0 in) is respected during cable routing to avoid signal degradation.
• Tighten the probe case to bearing housings using a recommended installation torque of 11.2 N-m (100 in-lbf). Maximum rated torque is 33.9 N-m (300 in-lbf).
• Route probe cable using proper shielding and grounding practices to avoid electromagnetic and radio frequency interference in vibration monitoring paths.
