Description

Option 01 (10 mm unthreaded length), Option 17 (170 mm overall case length), Option 05 (0.5 m total length), Option 01 (ClickLoc connector with connector protector, standard cable), and suffix -CN specify this metric armored 3300 XL 8 mm proximity probe configuration — 330104-01-17-05-01-CN.

This eddy-current proximity probe belongs to the Bently Nevada 3300 XL series and features an M10 x 1 metric thread with stainless steel armor. Unlike non-armored variants, the 330104 model is configured with robust protective armor over the probe lead. This specific configuration includes a pre-installed connector protector on its miniature male coaxial ClickLoc connector to shield the connection from moisture and environmental contaminants. The probe is used for non-contact vibration and position measurements on rotating machinery, and it carries NEPSI and CCC certifications under the -CN China hazardous area approval package.

Features

• Option 01 specifying a 10 mm unthreaded length on a total case length of 170 mm.
• Option 17 providing an overall M10 x 1 threaded case length of 170 mm.
• Option 05 configuring a 0.5 meter (1.6 feet) total probe cable length.
• Option 01 offering a miniature male coaxial ClickLoc connector with an integrated fluorosilicone connector protector.
• Stainless steel armor casing over the standard coaxial cable for mechanical protection.
• Suffix -CN incorporating the China hazardous area approval package with NEPSI and CCC markings.
• Interchangeable with other 3300 XL 8 mm components in a complete 5-meter transducer system.

Applications

The 330104 series proximity probe is used in machinery protection systems to monitor rotating machinery components. Typical applications include:

• Shaft radial vibration monitoring in steam turbines, gas turbines, and large industrial compressors.
• Axial thrust position monitoring in power generation turbines and petrochemical pumps.
• Keyphasor and speed measurements on rotating shafts in harsh industrial environments.
• Bearing oil film clearance and eccentricity measurement on industrial gearboxes and fans.

Installation Guidelines

Proper installation of the proximity probe is critical for accurate measurements and longevity. Follow these standard engineering practices:

• Probe Thread Engagement: Maximum thread engagement for M10 x 1 thread is 15 mm. Over-tightening or exceeding this length can cause binding and physical damage to the casing.
• Unthreaded Length Safety: The unthreaded length must be selected carefully to ensure the probe tip does not contact the rotating target when fully seated.
• Cable Routing and Minimum Bend Radius: Route the armored cable away from high-voltage wiring to minimize electrical noise. Avoid sharp bends; the standard minimum bend radius for armored probe cables is 25.4 mm (1.0 in).
• Connector Protection: Ensure the pre-installed fluorosilicone connector protector is completely sealed when mating the ClickLoc connector with the extension cable. Hand-tighten the coaxial connectors to secure the "click" connection.
• Hazardous Area Grounding: For installations adhering to the -CN NEPSI/CCC requirements, ensure correct intrinsic safety grounding and barriers are used according to regional industrial safety standards.

Compliance and Certifications

This configuration complies with the following standards and environmental certifications:

• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation) - Certified for intrinsically safe and non-sparking applications under suffix -CN.
• CCC (China Compulsory Certificate) - Certified for safety standards and hazardous area use in the People's Republic of China.
• RoHS compliant.
