Quick Detail

Description

The 21000-28-05-20-044-04-02 Proximity Probe Housing Assemblies is a precision-engineered, rugged mounting solution manufactured by Bently Nevada, a global leader in machinery protection and condition monitoring systems, with its origin in the USA. As a specialized component designed to complement the 3300 XL 8 mm proximity probe with connector protector, this housing assembly is built to provide secure, stable, and industry-compliant installation for proximity probes in critical industrial machinery monitoring applications. The assembly features a 0.5-meter (20 in) probe cable length, a 2 in standoff adapter (Option C Dimension), and a 4.4 in probe penetration (Option D Dimension), tailored to meet the specific spatial requirements of machinery such as turbines, compressors, and pumps where accurate vibration and displacement measurement are essential. Constructed with a durable aluminum body and a 304 stainless steel sleeve, the 21000-28-05-20-044-04-02 proximity probe housing assembly delivers exceptional corrosion resistance and structural stability, withstanding harsh industrial environments including exposure to oil, moisture, and chemical vapors. It is equipped with a 3/4-14 NPT mounting thread and one 3/4-14 NPT plug only, ensuring seamless compatibility with standard industrial mounting interfaces and compliance with API 670 standards—a critical benchmark for machinery protection systems in oil and gas, petrochemical, and power generation sectors.

Applications

The 21000-28-05-20-044-04-02 Proximity Probe Housing Assemblies is primarily applied in power generation facilities for mounting 3300 XL 8 mm proximity probes on steam and gas turbines, its 4.4 in probe penetration and 2 in standoff adapter enabling precise detection of shaft vibration and axial displacement to prevent catastrophic rotor-stator contact and extend turbine service life.

This aluminum and stainless steel housing assembly is widely deployed in petrochemical and oil refinery plants, providing secure installation for proximity probes on centrifugal compressors and pipeline pumps; its 3/4-14 NPT mounting thread ensures API 670-compliant integration, while the corrosion-resistant construction withstands exposure to hydrocarbon vapors and lubricating oils in harsh processing environments.

With its compact 4.3x3.2x9cm size and 0.25kg weight, the 21000-28-05-20-044-04-02 Proximity Probe Housing Assemblies is ideal for retrofit projects in legacy manufacturing machinery, allowing seamless integration of 3300 XL 8 mm proximity probes into existing equipment without modifying the original mounting layout, and upgrading condition monitoring capabilities for aging pumps and gearboxes.

Specifications

Competitive Advantage

1. Durable Dual-Material Construction for Harsh Environment Resistance

The housing assembly features an aluminum body paired with a 304 stainless steel sleeve, delivering superior corrosion resistance and structural stability compared to single-material alternatives; this robust design withstands exposure to oil, moisture, and chemical vapors in petrochemical and power generation environments, extending service life and reducing maintenance frequency.

2. API 670-Compliant Mounting Design for Industry-Standard Integration

Equipped with a 3/4-14 NPT mounting thread and plug, the assembly fully complies with API 670 standards for machinery protection systems; this compliance eliminates the need for custom adapters, simplifies installation on turbines, compressors, and pumps, and ensures consistent measurement accuracy for critical asset monitoring.

3. Optimized Dimensional Configuration for Space-Constrained Installations

Featuring a 2 in standoff adapter, 4.4 in probe penetration, compact 4.3x3.2x9cm dimensions, and 0.25kg lightweight design, the assembly is tailored for installation in tight machinery compartments; this spatial optimization enables precise proximity probe positioning where bulkier housing assemblies cannot fit, without compromising on measurement performance.
