Bently Nevada 21000-16-10-15-071-03-02 21000 Series Proximity Probe Housing Assembly

Description

Physical protection and precise alignment of proximity sensors in heavy rotating machinery are critical to ensuring reliable vibration and position measurements. The Bently Nevada 21000-16-10-15-071-03-02 is a robust, dome-style proximity probe housing assembly engineered specifically to shield delicate transducer components from mechanical impacts, process fluids, and harsh environmental conditions. Constructed from high-strength material, this housing simplifies installation by allowing maintenance personnel to adjust the probe penetration depth and gap externally without removing the assembly or exposing the interior of the machine.

This housing assembly is commonly deployed alongside Bently Nevada 3300 and 3300 XL proximity transducer systems. Its multi-point configuration options facilitate seamless integration with existing machinery casings, conduits, and junction boxes. The modular configuration indicated by the 21000-16-10-15-071-03-02 part number defines specific parameters for the probe thread size, penetration depth, electrical conduit fitting, casing mounting thread, and explosion-proof/environmental ratings.

Features

• Provides robust physical shield for proximity probes against environmental contaminants and mechanical hazards.
• Facilitates external probe adjustment and positioning without exposing internal machinery components.
• Designed with high-quality sealing gaskets and O-rings to maintain process pressure and environmental integrity.
• Compatible with a wide selection of Bently Nevada 3300 XL 8mm and standard proximity probes.
• Constructed from corrosion-resistant aluminum alloy for long-term survival in coastal and high-humidity environments.

Applications

• Steam and gas turbine vibration monitoring systems.
• Centrifugal compressor radial shaft vibration and axial thrust measurements.
• Industrial gearbox casing installations.
• Heavy pump shaft position and speed monitoring.
• Hydroelectric generator shaft alignment.

Technical Specifications

Installation Guidelines

• Ensure that the machine casing mounting threads are clean, free of burrs, and match the housing thread specification.
• Apply a suitable high-temperature thread sealant or O-ring lubricant to maintain pressure-tight joints.
• Verify probe gap voltage before final tightening of the locknut to guarantee accurate sensor calibration.
• Route extension cables through certified liquid-tight or explosion-proof conduit systems to preserve hazardous area ratings.
