Description

Fully threaded 3/8-24 UNF steel probe body (Option 00) with 1.7 in case (Option 17) and 1.0 m lead (Option 10) — 330101-00-17-10-02-CN.

This 3300 XL 8 mm proximity probe operates on the eddy-current principle to provide non-contact vibration and shaft position measurements. It interfaces with a 3300 XL Proximitor sensor and standard extension cable within a machinery protection system, transmitting precise dynamic displacement data for critical rotating machinery. Unlike armored configurations, this variant features a flexible, unarmored standard coaxial cable with a miniature ClickLoc connector.

Specifying Option 02 equips this probe with a miniature coaxial ClickLoc connector and standard cable without a connector protector, suited for installation environments where space is restricted or external conduit routing is used. The -CN trailing suffix certifies this unit with the China hazardous area approval package, including NEPSI and CCC markings. This certification makes it suitable for deployment in regulated petrochemical, gas, and power generation facilities in the Chinese market, matching the electrical and physical performance of standard 3300 XL systems.

Features

• Option 00 unthreaded case design provides a fully threaded 3/8-24 UNF body for maximum mounting adjustment flexibility.
• Option 17 overall case length of 1.7 inches supports medium-depth insertion inside bearing housings or casings.
• Option 10 specifies a 1.0-meter (3.3 feet) integrated probe cable, sized to connect to a 3300 XL extension cable.
• Option 02 provides an unarmored standard coaxial cable terminated with a miniature coaxial ClickLoc connector.
• China hazardous area approval package (-CN) provides NEPSI and CCC certifications for restricted industrial areas.
• Eddy-current operating principle provides high-precision non-contact shaft displacement and vibration measurement.
• Rugged 8 mm tip constructed from polyphenylene sulfide (PPS) resists chemical attack and moisture ingress.
• Corrosion-resistant AISI 303 stainless steel thread material protects the probe body in wet or oily machine environments.

Applications

Typical industrial scenarios include:

• Steam and gas turbine shaft vibration monitoring.
• Radial vibration and axial position (thrust) tracking on high-speed turbines.
• Rotor displacement analysis in centrifugal compressors and large industrial pumps.
• Bearing oil film thickness and housing expansion monitoring.
• Permanent installation on critical rotating machines requiring continuous machinery protection.

Installation Guidelines

• Mount the probe using the appropriate probe gap (typically 1.27 mm or 50 mils for standard calibration with an AISI 4140 target).
• Set thread engagement length carefully; maximum engagement is standardly 0.563 inches for 3/8-24 UNF threads to prevent binding.
• Ensure the probe cable is routed away from high-voltage sources and secured using proper conduit or mounting clamps.
• Apply standard shielding and grounding practices: ground the shield of the extension cable at the Proximitor sensor end only; isolate the probe body from local ground if necessary.
• Protect the miniature ClickLoc coaxial connection from moisture and oil exposure; clean with electronics contact cleaner before connection if contamination occurs.

Compliance and Certifications

• China Hazardous Area Approval Package (-CN)
• NEPSI (National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation)
• CCC (China Compulsory Certification) for hazardous environments
• RoHS compliant
• Compliant with directive standards for non-contacting transducer system environments when installed per Bently Nevada drawing 141092 or 140979.
