Description

The Bently Nevada 330101-00-58-10-02-CN is an unarmored 8 mm proximity probe specifically configured with a 5.8-inch fully threaded case (0.0 inches unthreaded length), a 1.0-meter total standard coaxial cable length, a miniature coaxial ClickLoc connector, and the specialized -CN China hazardous area approval package. Designed as a core component of the 3300 XL 8 mm Proximity Transducer System, this configuration is engineered for non-contact vibration and shaft position measurements in critical rotating machinery. By lacking heavy physical armor, this variant offers a highly flexible standard cable profile, making it easier to route through pre-existing protective conduit runs. This specific probe configuration is optimized for mainland China industrial applications where NEPSI and CCC hazardous zone certifications are mandatory, distinguishing it from sibling variants utilizing standard CSA/ATEX/IECEx approvals (such as the -05 option) or unapproved configurations (such as the -00 option).

Operating on the eddy-current principle, this probe pairs seamlessly with a 3300 XL series extension cable and a 330180 series Proximitor sensor. Together, they provide a continuous, linear voltage signal directly proportional to the distance between the probe tip and the target shaft surface. Built with a polyphenylene sulfide (PPS) tip and a rugged stainless steel thread body, the probe is highly resistant to corrosive chemical exposure, high temperatures, and the typical mechanical stresses found inside turbine, compressor, and pump bearing housings.

Features

• Eddy-current displacement measurement with an 8 mm tip diameter.
• 0.0 inches of unthreaded length, allowing the entire 5.8-inch case body to be utilized for deep thread-in depth adjustment.
• Unarmored 75 ohm coaxial cable providing exceptional routing flexibility inside industrial conduit.
• Equipped with a gold-plated miniature coaxial ClickLoc connector for corrosion-resistant, click-to-lock cabling connections.
• Fully sealed design to prevent process oil and moisture penetration between the tip and the stainless steel housing.
• Specifically approved with the -CN China safety package, featuring official NEPSI and CCC certifications.

Applications

• Steam and gas turbine shaft radial vibration and axial position monitoring.
• Rotor displacement and thrust position measurements on critical industrial compressors.
• Main oil pump shaft vibration analysis and protective shutdown systems.
• Bearing oil film clearance and expansion monitoring on large power-generation machinery.

Installation Guidelines

• Mount the probe with an appropriate physical gap relative to the shaft target, which is typically calibrated to 1.27 mm (50 mils) corresponding to a DC output of -10.0 Vdc.
• Do not exceed the maximum thread engagement length of 0.563 inches for the 3/8-24 UNF thread body to prevent mechanical binding.
• Ensure the 1.0-meter unarmored cable is routed through protective conduit or cable trays to guard against abrasion or chemical splashing inside the machine environment.
• Maintain a minimum bend radius of 25.4 mm (1.0 inch) when routing the standard coaxial cable to prevent internal signal impedance changes.
• Isolate the coaxial connectors at the extension cable junction point using protective connector sleeves to prevent grounding or moisture penetration.

Compliance and Certifications

The 330101-00-58-10-02-CN is certified for use in explosive and hazardous atmospheres in accordance with the specialized regional requirements of mainland China:

• NEPSI: Explosion-proof certification for hazardous gas and dust environments.
• CCC: China Compulsory Certification for industrial explosion-proof electrical equipment.
• -CN Approval Package: Confirms the application of official Chinese marking, safety warnings, and certification plaques directly on the hardware packaging.
