Product Description

Description

Engineered for demanding industrial environments, the Bently Nevada 21000-28-05-15-012-04-02 is an external proximity probe housing assembly designed to provide robust protection and simplified adjustment for proximity transducers. This assembly allows instrumentation engineers to install, calibrate, and service proximity probes externally without shutting down machinery or exposing personnel to hazardous process fluids.

The 21000-28-05-15-012-04-02 configuration features specific dimensional and thread specifications tailored for integration into machinery casings, such as steam turbines, gas turbines, compressors, pumps, and generators. By isolating the transducer within a dedicated protective sleeve, it ensures long-term operational reliability and precise gap adjustments for critical vibration and position monitoring systems.

Features

  • External Access Design: Facilitates probe installation, gap adjustment, and replacement without machinery shutdown or process fluid exposure.
  • Rugged Environmental Protection: Safeguards delicate coaxial cables and connectors from physical damage, moisture, and chemical exposure.
  • Precision Thread Engagement: Designed with standard NPT coupling threads for reliable and leak-tight industrial mounting.
  • Compatibility: Optimally configured for use with Bently Nevada 3300 XL 8 mm proximity probes.

Applications

  • Power generation plants (steam and gas turbine vibration monitoring)
  • Petrochemical and oil & gas refining equipment
  • Large-scale industrial centrifugal compressors and expanders
  • Critical cooling water pumps and balance-of-plant machinery
