Bently Nevada 330104-04-10-05-01-CN 3300 XL 8 mm Proximity Probe

Description

Option 04 (40 mm unthreaded length), Option 10 (100 mm case length), and Option 05 (0.5 m total length) specify this metric Bently Nevada 330104-04-10-05-01-CN 3300 XL 8 mm proximity probe configuration. This proximity probe features a threaded M10 x 1 metric housing and is wrapped in robust, flexible stainless steel armor that shields the 75-ohm triaxial cable from physical degradation in harsh operating environments. Complete with the -CN trailing suffix, this configuration includes the integrated China hazardous area approval package, certifying compliance under NEPSI and CCC regulations for installation in explosive and dust-prone industrial zones.

Used as part of a complete non-contacting machinery protection chain, this 3300 XL 8 mm probe works in tandem with standard extension cables and Proximitor sensors to deliver linear voltage changes proportional to shaft displacement. The shorter 0.5-meter overall probe length is optimized to connect outside the machine housing, reducing internal lead clutter and simplifying cable management. The integrated ClickLoc connector with connector protector (Option 01) safeguards the junction point from moisture and contaminant intrusion.

Features

• M10 x 1 Metric Thread: Robust stainless steel casing with standard metric thread pattern for precise gapping.
• 40 mm Unthreaded Length: Tailored Option 04 unthreaded design allows for specialized positioning constraints.
• 100 mm Overall Case: Option 10 case length allows deep penetration through outer machine housings or bearing caps.
• Flexible Armor Protection: Stainless steel armor over standard cable provides continuous physical guarding.
• 0.5 Meter Probe Lead: Compact 0.5-meter total length (Option 05) ideal for routing directly to junction boxes.
• Protected Connector Assembly: ClickLoc coaxial terminal fitted with an integrated connector protector (Option 01).
• China-Specific Approvals: Trailing suffix -CN guarantees NEPSI and CCC safety certifications for hazardous regional environments.

Applications

This proximity probe is used for shaft vibration, axial position, and speed measurements on rotating machinery. Typical environments include power generation steam turbines, petrochemical centrifugal compressors, industrial gas turbines, pumps, and fans operating in regions requiring local hazardous approvals.

Installation Guidelines

• Thread Engagement: Do not exceed 15 mm of maximum thread engagement length to avoid binding or housing damage.
• Torque Limits: Tighten the probe case to a maximum recommended torque of 7.5 N-m (66 in-lbf).
• Connector Care: Finger-tighten the miniature gold ClickLoc connector. Ensure the integrated connector protector is sliding properly to prevent moisture ingress.
• Bend Radius: Maintain a minimum cable bend radius of 25.4 mm (1.0 in) along the armored length to prevent signal attenuation or core fatigue.

Compliance and Certifications

• NEPSI: Certified for explosive gas and dust atmospheres in China under regional standards.
• CCC: China Compulsory Certification for hazardous locations.
• CE: European Community EMC Directive 2014/30/EU (EN 61000-6-2, EN 61000-6-4) and RoHS Directive 2011/65/EU.
• Functional Safety: SIL 2 (HFT = 0) and SIL 3 (HFT = 1) capable.
