Bently Nevada 330104-01-08-50-01-CN 3300 XL 8 mm Proximity Probe

Description

Option 01 (10 mm unthreaded length) and Option 08 (80 mm overall case length) specify this M10 x 1 threaded probe configuration with integrated armor—the Bently Nevada 330104-01-08-50-01-CN 3300 XL 8 mm proximity probe.

This metric-threaded transducer probe is equipped with integrated stainless steel armor, a 5.0-meter total length (Option 50), and a ClickLoc miniature coaxial connector with connector protector (Option 01). Operating as part of a 3300 XL 8 mm eddy-current measurement system, it works in conjunction with a 5.0-meter Proximitor sensor and extension cable. This variant carries the -CN suffix, which indicates the China hazardous area approval package containing NEPSI and CCC certifications. It measures shaft vibration, axial position, and speed on rotating machinery such as turbines, compressors, and industrial pumps.

Features

• M10 x 1 metric thread body configuration with stainless steel overall casing.
• Option 01 (10 mm) unthreaded length and Option 08 (80 mm) overall case length for specific machinery mounting depths.
• Option 50 (5.0-meter total length) probe lead designed for direct connection with 5-meter Proximitor systems.
• Integrated stainless steel armor protecting the coaxial cable from physical abrasion, cutting, and hot oil exposure.
• Option 01 ClickLoc coaxial connector equipped with a protective fluorosilicone sleeve to guard the connector junction against moisture and contaminants.
• -CN China hazardous area approval package certified under NEPSI and CCC guidelines for use in explosive atmospheres.
• 8.0 mm probe tip molded from durable Polyphenylene Sulfide (PPS) for chemical resistance in harsh industrial fluids.

Applications

• Shaft vibration and position monitoring in industrial rotating machinery.
• Radial vibration and axial thrust position measurements.
• Monitoring of steam turbines, gas turbines, centrifugal compressors, and generators.
• Applications requiring M10 x 1 metric threads and robust mechanical protection via flexible stainless steel armor.
• Hazardous area installations in China requiring NEPSI and CCC certifications.

Installation Guidelines

Proper installation of the 3300 XL M10 x 1 metric probe requires observing standard mechanical limits and electrical grounding practices. Ensure that the mounting bracket or hole is tapped cleanly for M10 x 1 threads. The maximum thread engagement length is 15 mm to prevent binding or stripping. Lock nuts should be tightened to the recommended torque limits to prevent loosening during operation. Protect the probe tip from contact with target surfaces during adjustment. Route the armored lead cable to prevent sharp bends, keeping a minimum bend radius of 25 mm. The coaxial connection to the extension cable must be clean, dry, and secure, with the connector protector slid firmly in place to seal out turbine oil and moisture.

Compliance and Certifications

This configuration is certified for use in hazardous industrial environments. The -CN suffix indicates a specialized approval package that conforms to Chinese national standards:

• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation)
• CCC (China Compulsory Certification)
• CE Compliant
• RoHS Directive Compliant (with EFUP of 15 years for associated cables)
