Bently Nevada 21000-16-10-00-098-04-02 Proximity Probe Housing

Overview

The 21000-16-10-00-098-04-02 is a specialized Proximity Probe Housing assembly from Bently Nevada’s 21000 series. This ruggedized aluminum housing is designed to protect proximity probes (typically 3300 XL 8mm or 5mm) in harsh industrial environments. It allows for the external adjustment of probe gaps without necessitating the disassembly of the machine’s internal components. This specific configuration is engineered for hazardous area installations, providing a weather-tight and explosion-proof enclosure for critical vibration and position monitoring sensors on turbines, compressors, and motors.

Detailed Specifications (Parsed Code)

The part number 21000-16-10-00-098-04-02 breaks down into the following technical parameters:

Operational Capabilities

The 21000-16-10-00-098-04-02 provides an IP66-rated environment for sensitive transducer components. The adjustable sleeve mechanism allows maintenance engineers to set the probe-to-target gap precisely, which is essential for accurate eddy current displacement measurements. The high-grade aluminum construction offers superior corrosion resistance and heat dissipation. It is typically paired with Bently Nevada’s 3300 XL Proximitor® sensors to ensure long-term stability in high-vibration machinery.

Technical FAQ

Can this housing be used with 11mm probes?

No, the -16 option in the part number designates a 3/8-24 thread, which is specific to 5mm and 8mm proximity probes. 11mm probes usually require the 24701 series or a different thread configuration.

What is the benefit of the -02 Approval Option?

The -02 suffix ensures the assembly is certified for use in North American and International hazardous locations (Class I, Div 1 and Zone 1). This includes flameproof and explosion-proof protection when installed with appropriate conduit seals.
