Bently Nevada 21000-16-10-15-088-03-02 Proximity Probe Housing Assembly

The Bently Nevada 21000-16-10-15-088-03-02 Proximity Probe Housing Assembly is a probe mounting and installation accessory designed for eddy current proximity transducer systems. This configuration is supplied for use with a 3300 XL 8 mm probe and provides a sealed mechanical interface that allows probe installation, adjustment, and cable routing through machine casings while maintaining environmental protection requirements.

Technical Specifications

Configuration Breakdown

This assembly is configured specifically for a 3300 XL 8 mm proximity probe. The -10 option provides a 1.0 m probe cable, while the -15 option includes a 1.5 in (38 mm) standoff adapter to achieve the required installation geometry.

The -088 penetration option provides an 8.8 in (224 mm) probe insertion depth, allowing the sensing tip to reach the required measurement point through machine housings or bearing cases. Correct penetration length is important when probe access is restricted by wall thickness or mounting arrangements.

Mechanical Construction

The housing body is manufactured from epoxy-painted A380.0 aluminum, providing a durable enclosure for the probe assembly. A 304 stainless steel sleeve is incorporated in the design to support probe positioning and adjustment while maintaining corrosion resistance in industrial installations.

The assembly uses a 3/4-14 NPT mounting thread and is supplied with one 3/4-14 NPT plug and one cable seal grip. These components help maintain enclosure integrity when installed according to the specified requirements.

Application in Proximity Measurement Systems

The housing assembly serves as the mechanical interface between the machine and the proximity probe system. It allows the probe to be installed externally while positioning the sensing tip accurately relative to the rotating shaft or target surface.

When used with compatible Bently Nevada proximity transducer systems, the housing simplifies probe installation, maintenance access, and gap adjustment without requiring direct modification of the sensing probe itself.

Environmental Protection

With the specified fittings correctly installed, the housing assembly meets CSA Type 4 enclosure requirements. This rating helps protect the probe installation against environmental exposure while supporting reliable operation of the vibration and position monitoring system.

The assembly is designed to support installations that follow API 670 vibration monitoring practices, making it suitable for machinery protection and condition monitoring applications where API-compliant installation methods are required.

Frequently Asked Questions

Q: Which probe is supplied for this configuration?

A: Option -16 specifies compatibility with a 3300 XL 8 mm probe. The housing assembly configuration is built around this probe type and associated mounting dimensions.

Q: What is the probe penetration length of this model?

A: Option -088 provides a probe penetration of 8.8 in (224 mm), allowing the probe tip to reach measurement locations inside machine housings or bearing compartments.

Q: What mounting thread does the housing assembly use?

A: The -02 mounting thread option specifies a 3/4-14 NPT connection. The assembly also includes a 3/4-14 NPT plug and a cable seal grip as defined by the fittings option.
