Bently Nevada 330904-00-03-70-01-CN 3300 XL NSv Proximity Probe

Description

The 330904-00-03-70-01-CN is a specialized 3300 XL NSv proximity probe designed for machinery monitoring in constrained spaces. This configuration features an M8x1 thread with integrated stainless steel armor for physical protection in demanding industrial environments. It includes a 0.0-inch unthreaded length (Option 00) and a 0.3-inch case length (Option 03), paired with a 7.0-meter total system length (Option 70). The connection is facilitated via a miniature coaxial ClickLoc connector with an integrated connector protector and standard cable (Option 01). This unit is supplied with the -CN China hazardous area approval package, ensuring compliance with NEPSI and CCC requirements for operation in designated regions.

The 3300 XL NSv Proximity Transducer System is engineered for applications where target area or physical space is limited, such as aeroderivative turbines, refrigeration compressors, and small-bore machinery. It provides precise non-contact measurement of radial shaft vibration, axial position, and speed. The NSv system is optimized for use with smaller target geometries, including shafts smaller than 51 mm or axial targets smaller than 15 mm, providing a reliable alternative to standard 3300 XL 8 mm probes where side-view or counterbore restrictions exist.

Features

• M8x1 thread with armor: Robust probe design (Model 330904) with stainless steel armor for enhanced mechanical durability.
• Option 00 (0.0 in): Fully threaded case length provides maximum mounting flexibility in shallow installations.
• Option 01 (Connector/Cable): Miniature coaxial ClickLoc connector featuring an environmental connector protector for reliable signal integrity.
• Option 70 (7.0 m): Standardized total system length for balanced signal transmission in medium-span machinery trains.
• Suffix -CN: Includes hazardous area approval certification for China (NEPSI/CCC).
• System Compatibility: Designed for seamless integration with 3300 XL NSv Proximitor sensors and 3300 NSv extension cables.

Applications

• Radial vibration and radial position measurement on fluid-filmed bearing machines.
• Axial (thrust) position monitoring.
• Tachometer and zero speed signal generation.
• Phase reference (Keyphasor) applications on high-speed equipment.
• Tight-clearance machinery installations where standard 8 mm probes are restricted.

Installation Guidelines

• Ensure the probe is installed with the specified connector protector to maintain IP environmental sealing.
• Verify Proximitor sensor is mounted on a compatible DIN rail or panel surface using appropriate isolation pads to prevent ground loops.
• Maintain proper cable routing to prevent mechanical stress on the ClickLoc connection points.
• Follow Bently Nevada installation drawings for all hazardous area classifications to maintain intrinsic safety (ia) or non-incendive (nA/ec) protection levels.

Compliance and Certifications

• Regional Approval: NEPSI, CCC (-CN suffix package)
• Compliance: EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU
• Functional Safety: SIL 2 (HFT=0) / SIL 3 (HFT=1)
