The Bently Nevada 21000-28-05-15-027-01-02 is widely used on steam turbines, gas turbines, centrifugal compressors, pumps, motors, generators, and other critical rotating equipment in power generation, oil and gas, petrochemical, mining, and heavy industrial facilities. Its rugged aluminum construction, integrated 3300 XL 8 mm probe, flexible mounting configuration, and compatibility with the 3300 XL Proximity Transducer System make it a dependable solution for long-term machinery protection and condition monitoring.
  • Oil and Gas: Covers upstream extraction, midstream compression, and downstream refining
  • Power Generation: Steam, gas, and hydro turbine-generators
  • Petrochemical: Large pumps, centrifugal compressors, and electric motors
  • Radial Vibration: Monitors dynamic shaft motion in fluid-film journal bearings
  • Axial Position (Thrust): Tracks axial shaft displacement to prevent internal rubbing

Verify depth: Measure your 2.7-inch probe penetration requirement against the machine bore to ensure proper tip clearance from the observed shaft target.
Wrap threads: Apply approved thread sealant to the 3/4-14 NPT mounting threads on the probe sleeve.
Insert assembly: Carefully thread the housing sleeve into the machine mounting hole, making sure not to bend or twist the internal 0.5-meter probe cable.
Secure housing: Tighten the housing body firmly to create a seal, ensuring the internal reverse-mount probe points squarely at the target surface.
