Bently Nevada 21000-00-00-55-060-03-02 21000 Proximity Probe Housing Assembly

Description

The Bently Nevada 21000-00-00-55-060-03-02 is a 21000 Proximity Probe Housing Assembly designed to provide a protected external mounting solution for proximity probes installed on rotating machinery. The housing assembly allows the probe to be mounted in a reverse configuration, enabling probe gap adjustment or probe replacement from outside the machine without dismantling major equipment. It is intended for machinery protection applications requiring an externally mounted probe housing in accordance with API 670 installation practices. This configuration is supplied without a proximity probe, probe cable, or standoff adapter. When used with a compatible Bently Nevada 3300 series or 3300 XL proximity transducer system, it provides reliable support for shaft vibration, shaft position, and rotational reference measurements while protecting the transducer installation and simplifying routine maintenance.

Frequently asked questions

Q:What fittings are supplied with this housing assembly?
A:Option 03 includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and one cable seal grip with interchangeable grommets for multiple cable diameters.

Q:Does the 21000-00-00-55-060-03-02 comply with API 670?
A:Yes. The 21000 Proximity Probe Housing Assembly is designed for externally mounted probe installations that meet the installation practices defined by API 670 for machinery protection systems.

Q:What does the "55-060" configuration represent?
A:The 55 option specifies a 5.5-inch standoff adapter length, while the 060 option specifies a 6.0-inch probe penetration. This configuration is intended for installations requiring an extended probe mounting distance through the machine casing.

Application areas

• Steam Turbine Monitoring – Installed on utility and industrial steam turbines where proximity probes are mounted through the turbine casing to monitor shaft vibration and shaft position. The external housing allows maintenance personnel to inspect, adjust, or replace the probe without opening the turbine, reducing outage time during scheduled maintenance.
• Gas Turbine Systems – Used on gas turbines operating in power generation and mechanical drive applications. The housing provides a protected installation for the proximity probe and helps maintain stable measurement of shaft movement under high-speed operating conditions.
• Centrifugal Compressor Packages – Applied to compressors in natural gas processing, petrochemical plants, and refinery facilities. The assembly supports continuous shaft vibration monitoring while protecting the probe installation from dirt, moisture, and mechanical damage commonly found in compressor environments.
