Bently Nevada 330101-00-50-10-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-50-10-02-05 specifies this unarmored 3300 XL 8 mm proximity probe configuration, defined by a fully threaded 3/8-24 UNF steel probe body (0.0 in unthreaded length) and an overall case length of 5.0 in. Equipped with a 1.0-meter standard coaxial cable ending in a miniature ClickLoc connector, this unit carries multiple agency approvals (CSA, ATEX, and IECEx) for installation in hazardous environments.

This eddy-current proximity probe serves within 3300 XL transducer systems to deliver non-contact displacement measurements. It is matched with a 3300 XL Proximitor sensor and standard extension cable to monitor shaft vibration and axial position on steam or gas turbines, compressors, and pump rotors. This specific variant features a robust polyphenylene sulfide tip and stainless steel housing to withstand high-pressure and chemically harsh machine casing environments.

Features

• Fully threaded case (0.0 inches unthreaded length) allows flexible depth adjustments in mounting brackets.
• Overall case length of 5.0 inches (127 mm) accommodates deep-set bearing housing configurations.
• Standard 1.0-meter (3.3 feet) triaxial cable simplifies cable management when paired with an extension cable.
• Miniature coaxial ClickLoc connector provides secure electrical connection to extension cables without requiring a connector protector.
• Option 05 agency approval covers international hazardous areas, including CSA, ATEX, and IECEx certifications.
• Constructed with a polyphenylene sulfide tip and AISI 303/304 stainless steel body for physical durability.

Applications

Typical applications include:

• Steam and gas turbine shaft vibration and axial position monitoring
• Compressor rotor displacement and casing expansion measurements
• Industrial pump shaft thrust and radial vibration analysis
• Critical rotating machinery protection under API 670 standards

Installation Guidelines

To establish successful machine monitoring, follow these mechanical and electrical steps:

• Mount the probe with the appropriate probe gap set according to the target calibration, typically within the linear range of 1.27 mm (50 mils) to 2.0 mm (80 mils).
• Tighten the probe case using appropriate torque limits. Standard 3/8-24 UNF threaded cases should not exceed a maximum torque of 11.2 N-m (100 in-lbf).
• Route the triaxial cable through protective conduits or cable trays to prevent mechanical damage. Maintain a minimum cable bend radius of 25.4 mm (1.0 in).
• Apply proper shielding and grounding practices at the Proximitor sensor interface to prevent EMI and cross-talk from adjacent machinery.

Compliance and Certifications

This proximity probe is compliant with international safety and environmental standards, particularly when specified with Option 05:

• CSA Approval for Hazardous Locations
• ATEX Zone 0, Zone 1, and Zone 2 Intrinsically Safe Certifications
• IECEx Certification for explosive atmospheres
• RoHS compliant
