Description

The 21000-28-05-35-020-04-02 is a Bently Nevada proximity probe housing assembly engineered for the secure mounting and environmental protection of 3300 XL 8 mm proximity probes. This configuration integrates a 0.5 m cable length (Option 05), a 3.5 in standoff adapter (Option 35), and 2.0 in of probe penetration depth (Option 020). It includes a 3/4-14 NPT plug for the fitting interface (Option 04) and utilizes a 3/4-14 NPT mounting thread (Option 02) to ensure rigid installation on industrial machinery.

This assembly serves as an essential component for critical machinery monitoring, providing the necessary mechanical support and sealing required to maintain accurate shaft vibration and axial position measurements. The housing features an aluminum body with a 304 stainless steel sleeve to withstand demanding operating environments.

Features

  • Probe Mounting (Option 28): Compatible with 3300 XL 8 mm proximity probes, including selectable hazardous area approvals.
  • Probe Cable Length (Option 05): Configured for 0.5 m (20 in) probe lead.
  • Standoff Adapter (Option 35): Provides a 3.5 in standoff length for specific installation clearances.
  • Probe Penetration (Option 020): Set for 2.0 in of probe penetration into the machine case.
  • Fittings (Option 04): Includes one 3/4-14 NPT plug.
  • Mounting Thread (Option 02): 3/4-14 NPT thread for standard housing installation.
  • Construction: Durable aluminum body with 304 stainless steel sleeve for reliable performance.

Applications

  • Industrial rotating machinery protection
  • Steam and gas turbines
  • Centrifugal compressors and pumps
  • Fans and blowers
  • Shaft vibration and axial position measurement
