Bently Nevada 330101-00-25-05-01-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length), Option 25 (2.5 in overall case length), and Option 05 (0.5 meter total length) specify this unique configuration of the Bently Nevada 330101-00-25-05-01-05, an eddy-current 8 mm proximity probe.

This probe does not include armored sleeving, distinguishing it from armored alternatives like the 330102 series. The integrated standard cable features a miniature ClickLoc coaxial connector equipped with a protective sleeve (Option 01), safeguarding the connection interface in challenging rotating machinery environments. The transducer assembly meets hazardous area requirements with ATEX, IECEx, and CSA approvals (Option 05), facilitating integration into global machinery monitoring installations.

Features

• Option 00 specifies a 0.0 in unthreaded body length, offering a fully threaded probe casing for direct insertion.
• Option 25 specifies a 2.5 in overall case length with standard 3/8-24 UNF-2A threads for bearing housing installation.
• Option 05 specifies a 0.5 meter (1.6 feet) total probe length, designed for compact routing and direct connection to standard extension cables.
• Option 01 provides a miniature coaxial ClickLoc connector with an integrated connector protector to resist environmental contamination.
• Option 05 provides global safety agency approvals including CSA, ATEX, and IECEx certifications for hazardous area compliance.
• Unarmored design provides a smaller outer profile for installation in tight spaces where mechanical abrasion is not a primary concern.
• Probe tip made of polyphenylene sulfide (PPS) to withstand exposure to industrial lubricants and gases.

Applications

Used in various heavy industries for continuous machinery health monitoring and machinery protection systems. Typical application fields include:

• Steam and gas turbine shaft vibration and position monitoring
• Compressor and pump rotor dynamic displacement measurements
• Hydroelectric generator shaft alignment and axial position tracking
• Industrial gearbox shaft monitoring in petrochemical and refining facilities
• Continuous vibration analysis on critical rotating machinery components

Installation Guidelines

• Verify the probe gap is calibrated against the target material (standard target is AISI 4140 steel) using a micrometer before securing the case.
• Install the probe with standard case torque, not to exceed 22.6 N-m (200 in-lbf) for standard forward-mounted probes.
• Maintain the minimum cable bend radius of 25.4 mm (1.0 in) to prevent damage to the internal triaxial conductors.
• Ensure the ClickLoc connectors are connected finger-tight to establish the lock with positive tactile click feedback.
• Use the integrated connector protector to isolate connection points from moisture, hydraulic fluids, and mechanical damage.

Compliance and Certifications

• CSA (Canadian Standards Association) hazardous area approval
• ATEX certification for explosive atmospheres
• IECEx certification for hazardous environments
