Description

For non-contact shaft displacement and vibration monitoring, the Bently Nevada 330101-30-10-02-05 proximity probe delivers exceptional mechanical durability and high-fidelity signal performance. This specific configuration features a 3.0-inch overall case length with no unthreaded portion, a 1.0-meter (3.3 feet) total cable length, a standard miniature coaxial ClickLoc connector, and CSA/ATEX/IECEx hazardous area approvals. Unlike armored or metric variants, this unarmored 3/8-24 UNF English threaded probe is designed for direct mounting on machine casings or bearing housings where space is defined and external protection conduits are already provided.

Operating as part of the 3300 XL 8 mm proximity transducer system, this probe works on the eddy-current principle to measure static position and dynamic vibration. It is fully compatible with the Bently Nevada 330180 series Proximitor sensors and 330130 series extension cables, making it a reliable component in machinery protection systems such as the 3500 monitoring rack.

Features

• Standard 8 mm tip diameter optimized for non-contact eddy-current displacement measurement
• Rugged stainless steel probe body designed for permanent installation in challenging industrial environments
• Standard English 3/8-24 UNF threaded body, supplied without external protective armor
• Integrated miniature coaxial ClickLoc connector ensures a secure, low-loss connection to the extension cable
• Fully compliant with major hazardous area safety standards (CSA, ATEX, IECEx)

Applications

This proximity probe is typically deployed in heavy-industry sectors such as power generation, oil and gas, and petrochemical refining. It is widely used for:

• Steam and gas turbine shaft vibration and axial position measurement
• Compressor and pump rotor displacement monitoring
• Radial vibration and thrust position tracking on fluid-film bearing housings
• Critical rotating machinery protection in multi-channel monitoring chains

Installation Guidelines

For reliable and noise-free monitoring performance, adhere to the following installation guidelines:

• Mount the probe with the appropriate probe gap (per system calibration, typically targeted near the linear range midpoint at -10.0 VDC bias) to ensure linear vibration measurement.
• Ensure proper cable routing, utilizing shielding and grounding practices that isolate the sensor signal from high-voltage electrical lines and EMI/RFI sources.
• Secure the probe body within the casing or housing using the supplied locknut with safety wire holes if required by the application.
• Handle the ClickLoc connector with care during connection and disconnect cycles, and ensure it is clean and dry before mating.
