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.

Features

  • Reverse mount configuration (Option 02) for case-mounted applications
  • 3/8-24 UNF threaded body (Option 02)
  • 1.2 in case length (Option 12)
  • 0.5 m system length (Option 05)
  • Standard click-loc connector (Option 02)
  • Integrated China hazardous area approval (-CN) package (NEPSI/CCC)
  • Designed for 3300 XL 8 mm proximity transducer system compatibility

Applications

The 330105 8 mm reverse mount probe is used in heavy industrial environments to measure shaft vibration and axial position on critical assets, including:

  • Steam and gas turbines
  • Centrifugal and axial compressors
  • Large pumps and motors
  • Fans and blowers
  • Hydroelectric generators
