Bently Nevada 330704-000-060-90-02-CN 3300 XL 11 mm Proximity Probe

Description

330704-000-060-90-02-CN specifies this 3300 XL 11 mm proximity probe configuration, which features a fully threaded M14 x 1.5 metric case protected by stainless steel armor, 0 mm unthreaded length (Option 000), 60 mm overall case length (Option 060), and a 9.0-meter standard coaxial cable (Option 90) terminating in a miniature ClickLoc connector (Option 02) with China hazardous area approvals (-CN).

Unlike standard non-armored or imperial-threaded configurations, the M14 x 1.5 metric threads and integrated stainless steel armor of the 330704 base model provide protection against harsh environments and physical abrasion. The 9.0-meter total length connects directly to compatible 9.0-meter systems without requiring a separate extension cable, simplifying installation in tight or remote machinery locations. The -CN suffix designates NEPSI and CCC certifications, satisfying safety requirements for explosive atmospheres.

Features

• M14 x 1.5 Metric Thread with Armor: Base model 330704 incorporates integrated stainless steel armor with an FEP outer jacket over a metric-threaded AISI 304 stainless steel case.
• 0 mm Unthreaded Length: Option 000 designates a fully threaded case structure optimized for narrow or precise installation depths.
• 60 mm Case Length: Option 060 provides a standard 60 mm overall case length for structural flexibility.
• 9.0-Meter Total Length: Option 90 offers a 9.0-meter (29.5 feet) integral cable for direct connection in extended machinery configurations.
• Miniature ClickLoc Coaxial Connector: Option 02 includes a gold-plated miniature ClickLoc coaxial connector on standard triaxial cable (no connector protector).
• China Hazardous Area Approval (-CN): Trailing suffix adds NEPSI and CCC certifications for hazardous environments.

Applications

This proximity probe is used within 3300 XL 11 mm transducer systems for non-contacting vibration and position monitoring in critical industrial machinery, including:

• Steam turbine differential expansion and axial (thrust) position measurements
• Reciprocating compressor rod position and rod drop measurements
• Radial vibration and shaft position measurements on fluid film bearing machines
• Tachometer, zero-speed, and Phase reference (Keyphasor) signal generation
• Industrial installations in China requiring NEPSI and CCC safety certifications

Installation Guidelines

• Torque Limits: Tighten the M14 x 1.5 metric threaded case to a recommended torque of 21.1 N-m (187 in-lb). Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb).
• Cable Bend Radius: Ensure the standard armored coaxial cable maintains a minimum bend radius of 25.4 mm (1.0 in) during routing to prevent internal conductor damage.
• Gap Configuration: Set the physical gap between the probe tip and the target to 2.5 mm (100 mils) for alignment in the center of the 4.0 mm linear range.
• Connector Integrity: Clean and dry the ClickLoc connector surfaces before joining. Connectors should be hand-tightened to finger-tight, or to a maximum torque of 0.565 N-m (5 in-lb).
• Armor Care: Protect the FEP-coated stainless steel armor from sharp bends or pinching, especially in high-vibration or abrasive environments.

Compliance and Certifications

• NEPSI: China hazardous area certification for explosive environments.
• CCC: China Compulsory Certification for industrial electrical safety.
• CE: European Union requirements (when paired with compliant 3300 XL Proximitor sensor).
• RoHS: Compliant with standard industrial environment hazardous materials limitations.
