Bently Nevada 21000-16-05-15-098-03-02 Proximity Probe Housing Assemblies

Core Specifications of the Housing Assembly

The 21000-16-05-15-098-03-02 belongs to the Bently Nevada 21000 series of proximity probe housing assemblies. This unit provides robust mechanical protection for eddy current probes in harsh industrial environments. Moreover, it simplifies field installation and maintains precise probe positioning.

Each assembly measures 16 mm in probe diameter and accommodates a 5 mm probe tip. Additionally, the housing weighs approximately 1.2 kg with all mounting hardware included. The 098 designation refers to a 0.98-inch bore depth, while the 03-02 suffix defines the fitting and thread configuration.

Interface and Mounting Details

The 21000-16-05-15-098-03-02 connects standard 3300 XL probes to machine casings. Consequently, technicians achieve repeatable gap settings without complex alignment tools. The housing includes a lock nut, sleeve, and sealing components. Therefore, it protects the probe from oil, dust, and mechanical stress.

This assembly uses a 3/4-16 UNF mounting thread for universal compatibility. Meanwhile, the stainless steel body resists corrosion in turbine and compressor environments.

Performance and Application Notes

Plant engineers select the 21000-16-05-15-098-03-02 for reliable probe protection. Furthermore, the four-part design allows quick field replacement without full disassembly. The housing stores no energy internally, since it serves a purely mechanical function. As a result, it adds no electrical load to the measurement chain.

Operators pair this assembly with 3300 XL probes and extension cables. In addition, the 0.98-inch bore depth ensures consistent probe tip clearance.
