Quick Detail

Description

The 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly is a high-performance, industry-compliant mounting solution engineered by Bently Nevada, a global leader in machinery condition monitoring technologies, specifically designed to optimize the functionality of 3300 XL 8mm proximity probes in demanding industrial environments. This Proximity Probe Housing Assembly is meticulously crafted to provide robust, secure, and precise positioning for proximity probes, ensuring reliable vibration, axial position, and radial displacement measurements for critical rotating machinery across oil and gas, petrochemical, power generation, and heavy manufacturing sectors. As a core component of Bently Nevada’s comprehensive monitoring ecosystem, the 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly is built to meet the strictest industry standards, delivering unparalleled durability and compatibility for mission-critical applications.

Featuring a lightweight yet rugged construction, the 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly combines an aluminum body with a 304 stainless steel sleeve, striking an optimal balance between corrosion resistance, structural stability, and weight efficiency (1.1kg total weight, dimensions 30x8.5x8.1cm). It is pre-configured to accommodate a 3300 XL 8mm probe with a connector protector and a 0.5-meter (20-inch) probe cable, ensuring seamless integration with Bently Nevada’s proven sensing technologies. The assembly is equipped with a 1/2-14 BSP mounting thread and one 3/4-14 NPT plug, enabling secure, standardized installation on a wide range of machinery frames and bearing housings. Its standoff adapter (Option C) offers a minimum length of 1.5 inches (38mm), while the probe penetration (Option D) reaches 5.6 inches—tailored to meet the spatial requirements of deep-set machinery components without compromising measurement accuracy.

Applications

The 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly is a core mounting solution for critical rotating machinery monitoring in the oil and gas sector, including onshore refineries, offshore drilling platforms, and pipeline compressor stations. Its robust aluminum-and-stainless-steel construction and API 670 compliance make it ideal for housing 3300 XL 8mm probes to measure shaft vibration, axial thrust, and radial displacement in high-pressure, corrosive environments, where it helps detect early-stage anomalies such as bearing wear and rotor misalignment to prevent costly equipment failures and ensure regulatory compliance.

This Proximity Probe Housing Assembly excels in power generation facilities, from thermal power plants to gas turbine installations, where it supports continuous condition monitoring of turbines, generators, and boiler feed pumps. Its wide operating temperature range (-56°C to +187°C) enables stable performance in both frigid outdoor equipment yards and high-temperature turbine enclosures, while its 5.6-inch probe penetration allows for precise measurement of deep-set shaft components, providing critical data for optimizing power plant efficiency and reducing maintenance downtime.

The 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly is widely used in heavy manufacturing industries, including steel mills, cement plants, and pulp and paper factories, where it is deployed on large motors, crushers, and mixers. Its compact dimensions (30x8.5x8.1cm) and 1/2-14 BSP mounting thread enable easy integration into space-constrained machinery layouts, while its compatibility with ceramic-capped probes expands its utility across diverse production lines. By ensuring accurate, reliable sensor positioning, it helps manufacturing operators implement predictive maintenance programs and maintain consistent production output.

Specifications

Competitive Advantage

1.Premium Material Construction for Durability and Corrosion Resistance

The 21000-34-05-15-056-04-02 Proximity Probe Housing Assembly features a dual-material design combining an aluminum body for lightweight efficiency and a 304 stainless steel sleeve for superior corrosion and wear resistance. This construction ensures the assembly can withstand harsh industrial environments, including exposure to saltwater, chemicals, and abrasive particulates, without compromising structural integrity. Compared to all-steel alternatives, it reduces installation weight by up to 30% while maintaining equivalent durability, making it ideal for machinery with strict load-bearing requirements.

2.Industry-Standard Compliance and Versatile Compatibility

Unlike generic probe housings that lack regulatory certification, this assembly fully complies with API 670 standards, a critical requirement for machinery protection systems in oil and gas, petrochemical, and power generation sectors. It is pre-engineered to work seamlessly with Bently Nevada’s 3300 XL 8mm proximity probes (with connector protector) and supports ceramic-capped probes when configured, ensuring compatibility with a wide range of sensing technologies. The 1/2-14 BSP mounting thread and 3/4-14 NPT plug enable standardized installation, eliminating the need for custom adapters and reducing setup time and costs.

3.Optimized Design for Extreme Environments and Precision Measurement

The assembly is built to operate across an ultra-wide temperature range (-56°C to +187°C), outperforming conventional housings that are limited to narrower thermal windows. Its 5.6-inch probe penetration and 1.5-inch minimum standoff adapter length are tailored to access deep-set machinery components, providing precise measurements of shaft position and vibration that are critical for predictive maintenance. Additionally, it supports optional accessories such as the 37948-01 probe support and oil seal, which mitigate vibration-induced inaccuracies and fluid ingress—addressing common pain points in long-term industrial deployments and extending the service life of both the housing and the integrated probe.
