Bently Nevada 330105-02-12-05-02-CN 3300 XL 8 mm Reverse Mount Probes

Description

330105-02-12-05-02-CN represents a 3300 XL 8 mm reverse mount proximity probe, configured with a 3/8-24 UNF thread (Option 02), a 1.2 in case length (Option 12), a 0.5 m system length (Option 05), and a connector/cable type with a click-loc connector and standard cable (Option 02). This configuration is optimized for reverse mount applications where the probe body is mounted through the machine case, suitable for shaft vibration and axial position measurements in critical rotating machinery.

This unit features the China hazardous area approval package (-CN), ensuring compliance with local NEPSI and CCC requirements. It operates as part of the 3300 XL 8 mm proximity transducer system, which is fully backward compatible with standard 3300 series components while providing improved RFI/EMI immunity and electrical performance. The probe connects directly to the 3300 XL Proximitor sensor through a matching extension cable to complete the monitoring signal chain.

Installation Guidelines

Ensure the probe is installed in a suitable reverse mount housing that secures the body against the machine casing. Maintain a minimum clearance of 1.27 mm (50 mils) from the target surface during installation. Use only Bently Nevada-certified extension cables to maintain system signal integrity and RFI/EMI shielding performance. For hazardous area installations, ensure the -CN configuration is verified against local site safety permits and that the surrounding environment is classified according to the NEPSI/CCC certification standards provided with the documentation.
