Bently Nevada 21000-16-05-00-064-04-02 Proximity Probe Housing Assembly

Description

The 21000-16-05-00-064-04-02 is a specialized Proximity Probe Housing Assembly designed to protect and mount proximity transducers in industrial machinery environments. This configuration features a 1.0 inch NPT conduit fitting (Option 16) and a 1/2 inch NPT mounting thread (Option 05), providing a secure, sealed interface for vibration and position monitoring cables. The assembly includes no internal probe (Option 00) and accommodates a 6.4 inch housing length (Option 064), with an optional 3/4 inch NPT pipe fitting (Option 04) and a standard mounting clamp (Option 02). This housing assembly ensures the environmental isolation of the proximity probe, protecting the cable connection from fluids, lubricants, and contaminants common in rotating machinery. It is compatible with standard Bently Nevada proximity probe systems and provides the mechanical stability necessary for consistent gap measurement on shafts and rotors.

Features

• Option 16: 1.0 inch NPT conduit fitting for cable protection
• Option 05: 1/2 inch NPT mounting thread for standard machine installation
• Option 00: No probe included, allowing for modular configuration
• Option 064: 6.4 inch housing length designed for specific clearance requirements
• Option 04: 3/4 inch NPT pipe fitting interface
• Option 02: Mounting clamp included for secure transducer fixation

Applications

The 21000 series housing assemblies are used in power generation, petrochemical processing, and oil and gas industries. They are essential for protecting transducer tips and cable terminations in turbine-generator sets, large motors, pumps, and compressors where machinery vibration and shaft position monitoring are required.

Installation Guidelines

Ensure the housing is mounted securely to the machine casing to minimize resonance. Verify that the NPT threads are properly sealed using compatible pipe thread sealant to prevent fluid ingress. Route cabling through the 1.0 inch NPT conduit fitting using appropriate seals or glands to maintain the environmental integrity of the transducer connection. Ensure the probe gap is set according to the specific transducer datasheet requirements before locking the assembly into position.
