Bently 330194-14-20-50-05

Product Overview The 330194-14-20-50-05 is an extended temperature range (ETR) eddy current proximity probe from Bently Nevada’s 3300 XL 8mm sensor system with enhanced features. This probe features M10x1 metric thread, 14mm unthreaded length, 20mm overall case length, 5.0 meter integral cable, armored construction, and CSA/ATEX/IECEx agency approvals. The longer 5.0 meter cable reduces or eliminates the need for a separate extension cable, and the armored construction provides superior mechanical protection. The hazardous location certifications enable use in explosive atmospheres.

Application Scenarios

  • Oil and gas production: Monitors compressors, pumps, and turbines in hazardous area classifications
  • Petrochemical processing: Measures shaft vibration in reactors, distillation columns, and process equipment in explosive atmospheres
  • Chemical plant rotating equipment: Monitors agitators, mixers, and pumps handling flammable chemicals
  • Offshore platform equipment: Certified for marine hazardous area installations
  • Natural gas pipeline compressors: Monitors pipeline compressors in hazardous locations
  • Refinery critical equipment: Measures vibration in catalytic crackers, hydrotreaters, and reformers
  • Pharmaceutical solvent handling: Monitors equipment in areas with flammable solvent vapors
  • Mining hazardous areas: Certified for use in underground and surface mining operations with explosive gases

Performance Parameters Identical electrical performance to other 3300 XL 8mm ETR probes. The 5.0 meter cable length provides more flexibility in probe placement relative to the Proximitor. The armored construction does not affect electrical performance. The hazardous location certifications ensure safe operation in specified explosive atmospheres without compromising measurement accuracy.
