Bently Nevada 330101-00-25-20-12-05 3300 XL 8 mm Proximity Probe

Description

330101-00-25-20-12-05: 3300 XL 8 mm proximity probe with a 3/8-24 UNF thread, configured with a 0.0 in unthreaded length (Option 00), 2.5 in overall case length (Option 25), 2.0 m total length (Option 20), ClickLoc connector on FluidLoc cable (Option 12), and CSA/ATEX/IECEx agency approvals (Option 05).

Unlike standard configurations that feature the default Option 02 cable, this variant is manufactured with FluidLoc cable (Option 12) which prevents oil and other process fluids from migrating through the interior of the probe cable. Additionally, the lack of a stainless steel armor jacket maintains high flexibility in tight spaces, while the Option 05 certification package ensures compliance in hazardous locations.

Features

• 8 mm tip diameter non-contact eddy-current displacement probe
• Fully threaded 3/8-24 UNF stainless steel probe body with 2.5 in overall case length
• FluidLoc cable option (Option 12) prevents fluid migration through the internal probe lead
• 2.0-meter (6.6 feet) total probe length, compatible with 3300 XL extension cables and Proximitor sensors
• ClickLoc coaxial connector provides direct connection without a connector protector
• Option 05 hazardous area approval package certified by CSA, ATEX, and IECEx

Applications

Typical rotating machinery protection and condition monitoring scenarios including:

• Steam and gas turbine shaft vibration and axial position measurement
• Compressor rotor displacement and thrust position monitoring
• Pump shaft radial vibration and rotational speed tracking
• Critical industrial machinery monitoring requiring high-temperature, fluid-resistant proximity probes

Technical Specifications

Installation Guidelines

• Mount the probe using the recommended probe case torque of 11.2 N-m (100 in-lbf). Do not exceed the maximum rated torque of 33.9 N-m (300 in-lbf) to prevent casing damage.
• Maintain a minimum bend radius of 25.4 mm (1.0 in) for the coaxial cable during routing.
• Set the probe gap to the correct calibrated value (typically 1.27 mm or 50 mils) before securing the lock nut.
• Route the FluidLoc cable with appropriate shielding and grounding procedures to minimize electrical noise interference in the monitoring chain.
• Avoid thread engagement lengths exceeding 14.3 mm (0.563 in) per industry standards to prevent binding.

Compliance and Certifications

• CSA, ATEX, IECEx Approvals (Option 05) for hazardous locations
