Professional Metric Machinery Protection

The Bently Nevada 32000-28-05-08-080-03-02 represents the metric equivalent of the industry-standard external probe housing series, specifically engineered for global industrial assets utilizing SI units. This assembly provides a ruggedized, environmental enclosure that allows technicians to install, adjust, and replace proximity probes from outside the machine casing. It is an indispensable component for high-speed compressors and turbines where internal access is impossible during operation. By protecting the probe and lead connection from oil, steam, and mechanical debris, this housing ensures the uninterrupted flow of critical vibration and thrust data to the Bently Nevada 3500 rack, maintaining the highest levels of safety and asset availability.

Metric Option Code Decoding

32000 - Metric Housing Base

Designates the Aluminum External Probe Housing utilizing metric threads and dimensions, optimized for international machinery standards.

28 - Probe Threaded Length (Dimension A)

Specifies a 28 mm threaded length for internal probe adjustment. This allows for precise axial positioning of the probe tip to achieve the required gap voltage.

05 - Proximity Probe Type

Indicates compatibility with M10 x 1 metric 8mm proximity probes (3300 or 3300 XL). The internal hardware is precisely machined for metric sensor integration.

08 - Fitting Option

Designates a specialized M20 x 1.5 cable entry fitting. This ensures a watertight and dust-tight seal for the field wiring according to European and international electrical standards.

080 - Sleeve Length (Dimension L)

Represents an 80 mm distance from the housing base to the probe tip area. This reach dimension ensures the probe sleeve penetrates the machine casing to the correct depth.

03 - Sleeve Thread Series

Specifies a G 3/4 (ISO 228/1) parallel pipe thread for the mounting sleeve. This is a standard interface for bearing housings in metric-designed machinery.

02 - Agency Approval

Designates ATEX/IECEx and CSA/NRTL/C hazardous area certifications, ensuring the assembly meets global explosion-proof and flame-proof requirements.

Technical & Dimensional Specifications

Precision Field Mounting Requirements

To maintain signal fidelity, the housing must be mounted to a rigid surface to prevent housing resonance from being interpreted as shaft vibration. When setting the probe gap, utilize a digital multimeter to monitor the DC voltage at the Proximitor; once the center-scale voltage (typically -10V) is reached, secure the internal lock nut. For hazardous area installations, ensure the M20 cable gland is certified to match the explosion-proof rating of the housing and utilize a thread sealant to prevent moisture ingress into the internal coaxial connection.

Engineering Performance Advantages

The 32000-28-05-08-080-03-02 excels in petrochemical and power generation environments where exposure to aggressive chemical vapors and high humidity is common. The cast aluminum housing provides excellent EMI shielding, protecting the high-impedance proximity signal from local electrical noise. Its primary engineering advantage is the "Live-Gap" feature—allowing engineers to recalibrate or replace sensors without a machine shutdown, a capability that directly reduces O&M costs. This metric assembly integrates perfectly with Bently Nevada 3500/42M monitors and high-speed DCS platforms like Honeywell Experion PKS.

Technical Field FAQs

Q1: Can I use a standard 3/8-24 UNF probe in this 32000 housing?

A1: No. The 32000 series is the metric version. You must use an M10 x 1 threaded proximity probe to match the internal mounting hardware of this assembly.

Q2: What is the significance of the 80 mm (080) dimension?

A2: This is the sleeve length. It represents the fixed distance the stainless steel tube extends from the housing. Ensure your machine casing thickness and standoff distance are compatible with this 80 mm reach.

Q3: Does this housing include the proximity probe?

A3: No, this is the housing assembly only. Probes and extension cables must be ordered separately based on your specific system length and sensitivity requirements.
