Bently Nevada 330101-00-13-10-12-CN 3300 XL 8 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 12 (coaxial ClickLoc connector with FluidLoc cable) specify this 3300 XL 8 mm proximity probe configuration — 330101-00-13-10-12-CN, which features a 1.3 in overall case length and is backed by regional China hazardous area approvals.

The 330101-00-13-10-12-CN probe operates on the eddy-current measurement principle for non-contact vibration and shaft position monitoring in 3300 XL monitoring systems. This configuration incorporates a FluidLoc cable, which provides an internal physical seal inside the triaxial core to block steam, oil, and process liquids from migrating through the cable assembly. It terminates in a miniature gold-plated coaxial ClickLoc connector which clicks when hand-tightened, ensuring a secure connection without tools. This probe is designated with the -CN suffix, indicating it includes a China hazardous area approval package certified by NEPSI and CCC, making it ideal for restricted hazardous environments in the region where standard global options are not compliant.

Features

• 3/8-24 UNF threaded stainless steel case with 1.3 in overall case length and 0.0 in unthreaded length.
• FluidLoc cable construction blocks oil and other industrial process fluids from migrating through the internal wire pathways.
• Gold-plated coaxial ClickLoc connector provides a secure connection that resists vibration and prevents loosening.
• Polyphenylene sulfide (PPS) probe tip offers high electrical insulation and structural resistance in aggressive fluid environments.
• 1.0 m FEP-insulated triaxial cable delivers excellent thermal stability and chemical resistance.
• Suffix -CN provides regional China certification markings, including NEPSI and CCC hazardous area compliance.
• Compatible with 3300 XL 8 mm Proximitor sensors (330180 series) and standard FEP extension cables in machine protection systems.

Applications

• Steam and gas turbine shaft vibration and radial displacement monitoring.
• Axial thrust position and shaft movement measurement on high-speed pumps and compressors.
• Rotor dynamic behavior assessment in heavy industrial rotating machinery.
• Permanent installations in generator bearing housings where liquid migration and high oil pressure are present.
• Machinery protection monitoring in hazardous industrial zones across China.

Installation Guidelines

• Mount the probe with the appropriate gap voltage (typically -10 Vdc to -11 Vdc, representing a gap of approximately 1.27 mm or 50 mils) against the target shaft.
• Ensure thread engagement in the bearing casing does not exceed 14.3 mm (0.563 in) to avoid binding or damage to the 3/8-24 threads.
• Maintain the minimum permissible bend radius of 25.4 mm (1.0 in) during cable routing to prevent attenuation or physical failure of the triaxial core.
• Route the FEP-insulated cable with proper shielding and grounding techniques to preserve low-noise signal integrity inside the turbine or machine housing.

Compliance and Certifications

• NEPSI (National Supervision and Inspection Centre for Explosion Protection and Safety of Instrumentation, China)
• CCC (China Compulsory Certification for Explosion Safety)
• CE Compliant
• RoHS Compliant
