Product Description

The Bently Nevada 21000-28-05-00-040-04-02 is a robustly engineered Proximity Probe Housing Assembly designed to provide superior physical and environmental protection for proximity probes in critical machinery monitoring applications. As an essential component of a comprehensive condition monitoring system, this housing ensures the precise and stable positioning of the probe relative to the machine shaft. This stability is paramount for acquiring accurate vibration, axial position, and speed measurements, which are vital inputs for the Bently Nevada 3500 and 3300 Series Machinery Protection Systems. The 21000-28-05-00-040-04-02 housing assembly is specifically designed to shield the delicate proximity probe from harsh industrial environments, including contaminants, moisture, and accidental physical impact, thereby preserving the integrity and reliability of the entire measurement channel and preventing costly false alarms or missed machinery faults.

This specific configuration, Bently Nevada 21000-28-05-00-040-04-02, is defined by its precise technical attributes for seamless integration. It features an unthreaded housing length of 2.8 inches (A) and includes a 0.5-inch standoff adapter (B), allowing for flexible installation and proper probe gap adjustment. This assembly is supplied without a probe or cable (C), providing the flexibility for engineers to select the appropriate Bently Nevada 3300 XL series probe based on the specific application requirements. Constructed from durable 304 Stainless Steel (D), the housing offers excellent corrosion resistance suitable for a wide range of industrial settings. The unit is equipped with a standard 3/4 – 14 NPT mounting thread (E) for secure installation into the machine casing. To complete the environmental seal, it includes a 3/4 – 14 NPT plug (F) for the conduit fitting, ensuring the internal probe and wiring are protected from external elements. Using a genuine Bently Nevada housing like the 21000-28-05-00-040-04-02 is critical for maintaining the performance specifications and agency approvals of your Bently Nevada monitoring system.

Proper installation of the Bently Nevada 21000-28-05-00-040-04-02 Proximity Probe Housing Assembly is a foundational step in establishing a reliable predictive maintenance program. By securely mounting and protecting the proximity sensor, this housing guarantees that the data fed into the monitoring system is an accurate reflection of the machine’s dynamic behavior. This reliability is essential for asset protection, enabling early detection of potential issues such as bearing wear, shaft imbalance, or misalignment. The use of these assemblies is a standard practice in industries where machinery uptime is critical and is often a requirement for compliance with standards such as API 670 (Machinery Protection Systems). The robust design and material selection of the 21000-28-05-00-040-04-02 ensure long-term performance and durability, reducing maintenance needs and safeguarding your investment in both the monitoring system and the rotating machinery it protects.
