Bently Nevada 330904-00-12-10-01-CN 3300 XL NSv Proximity Probe

Description

The 330904-00-12-10-01-CN is a 3300 XL NSv proximity probe engineered for non-contact vibration and position measurement in small-bore machinery and high-speed equipment. This configuration features an M8x1 threaded, armored probe body (Option 00, 0.0 in unthreaded length; Option 12, 1.2 in case length) with a 1.0 m total system length (Option 10). The probe is equipped with a miniature coaxial ClickLoc connector including a connector protector for enhanced environmental resilience (Option 01). This specific part number includes the -CN suffix, signifying a China hazardous area approval package compliant with NEPSI and CCC requirements. Designed for applications with limited target geometry, the 3300 XL NSv system maintains accuracy in tight clearance environments where standard probes might exhibit reduced scale factor stability. This probe is intended for use within the 3300 XL NSv transducer chain, which typically includes a matching Proximitor sensor and extension cable to ensure signal integrity and proper linear range performance.

Features

• M8x1 threaded probe body with stainless steel armor for mechanical protection
• 1.0 meter total probe length configuration
• Miniature coaxial ClickLoc connector for secure, reliable signal connection
• Integrated connector protector provides environmental shielding for the cable termination
• Optimized for small-bore, high-speed machinery vibration and axial position monitoring
• -CN suffix: Includes China hazardous area certification (NEPSI + CCC)

Applications

• Radial vibration monitoring on shafts smaller than 20 mm diameter
• Axial position measurement in aeroderivative gas turbines
• High-speed centrifugal compressors and pumps with limited clearance
• Critical machinery protection in petrochemical and power generation facilities

Installation Guidelines

• Ensure the probe is mounted using the supplied nuts to allow for gap adjustment.
• Install the connector protector on the probe-to-extension cable interface to prevent moisture ingress.
• Maintain at least 13 mm (0.5 in) of clearance for counterbores to prevent scale factor changes at far gaps.
• Verify total system length (Probe + Extension Cable) matches the calibrated Proximitor sensor length requirement.
• Grounding must follow standard hazardous area installation practices for NEPSI/CCC compliant zones.
