Bently Nevada 330101-36-80-10-02-05 3300 XL 8 mm Proximity Probe

Description

Designed for non-contact shaft vibration and displacement measurements, the Bently Nevada 330101-36-80-10-02-05 serves as a high-integrity 8 mm Proximity Probe within the 3300 XL monitoring system. This specific configuration features a 3.6-inch unthreaded probe casing, an 8.0-inch overall case length, and a 1.0-meter standard coaxial cable without armor. It is terminated with a standard miniature coaxial ClickLoc connector (without a connector protector) and is fully certified with CSA, ATEX, and IECEx hazardous area approvals. This physical layout is engineered to fit deeper installation clearances on critical industrial turbine and compressor housings while providing certified safety in explosive gas or dust environments.

Features

• Optimized Physical Geometry: 3.6-inch unthreaded length coupled with an 8.0-inch overall threaded case length, designed for deep penetration into machine casings and bearing housings.
• Standard Unarmored Cable: Features a 1.0-meter lightweight, standard 75-ohm coaxial cable for flexible routing and clean sensor terminal pairing.
• Robust Connection: Equipped with a miniature ClickLoc coaxial connector (option 02) ensuring secure, reliable, and tool-free system interconnectivity.
• Hazardous Location Certification: Fully approved under CSA, ATEX, and IECEx standards (option 05), facilitating deployment in regulated hazardous and explosive environments.
• Industrial Durability: Incorporates a ruggedized PPS plastic 8 mm tip and a corrosion-resistant stainless steel body for continuous machine casing installations.

Applications

The 330101-36-80-10-02-05 proximity probe is ideal for critical rotating machinery protection in power generation, oil and gas, petrochemical, and heavy industries. Typical installations include:

• Steam and gas turbine shaft dynamic radial vibration monitoring.
• High-speed centrifugal compressor rotor axial displacement measurements.
• Critical process pump bearing clearance and rotor position analysis.
• General turbomachinery protection compliant with API 670 standards.

Installation Guidelines

To ensure proper calibration and measurement accuracy of the proximity probe system, follow these technical recommendations:

• Mount the probe using the appropriate physical gap (typically set to a voltage output of -10 VDC or approximately 1.27 mm / 50 mils from the shaft face) per standard calibration procedures.
• Ensure the unthreaded casing length (3.6 inches) matches the internal sleeve geometry of the machine casing to prevent physical contact or interference.
• Route the 1.0-meter coaxial cable with proper industrial shielding and grounding practices, terminating shielding at the junction box/monitoring rack only to prevent ground loops.
• Avoid installing probes in close proximity to adjacent structural metals or other eddy-current fields to minimize crosstalk and distortion.

Compliance and Certifications

The 330101-36-80-10-02-05 is manufactured under rigorous quality control guidelines and is fully certified under the following standards:

• CSA: Certified for Class I, Division 1 and Division 2 hazardous environments.
• ATEX/IECEx: Approved for explosive gas and dust atmospheres (Zone 0, Zone 1, and Zone 2).
• API 670: Designed to satisfy standard machinery protection requirements for vibration, axial position, and speed monitoring.
