Bently Nevada 21000-33-05-00-035-03-02 21000 Proximity Probe Housing Assembly

Description

Designed for severe industrial environments, the Bently Nevada 21000-33-05-00-035-03-02 housing assembly facilitates the external mounting and precise positioning of proximity probes. This 21000 series housing permits probe replacement or adjustment without requiring machinery disassembly or process shutdown, minimizing operational downtime. Constructed from robust, corrosion-resistant materials, the enclosure protects the probe connection and cabling against mechanical impact, moisture ingress, and hazardous environments.

The configuration represented by the 21000-33-05-00-035-03-02 model designation indicates specific options for probe type compatibility, sleeve length, electrical certifications, and cable seal fittings. This assembly is standard for machinery protection systems where internal probe mounting is structurally or operationally impractical.

Features

• Allows external probe replacement and calibration adjustment while machinery is operational.
• Robust dome enclosure protects sensitive probe-to-extension cable connections.
• Integrates seamlessly with Bently Nevada 3300 and 3300 XL 8 mm proximity probes.
• Engineered to maintain casing seals and prevent fluid or gas leakage from the machine interior.
• Durable metallic housing with high corrosion resistance for petrochemical and outdoor exposure.

Applications

• Steam and gas turbine vibration monitoring systems.
• Centrifugal and reciprocating compressor shaft displacement tracking.
• Industrial pump casing vibration and axial thrust measurements.
• Hydroelectric generator shaft relative vibration monitoring.

Installation Guidelines

Mount the housing directly into the machine casing or a dedicated mounting bracket. Ensure thread-sealing compound is applied to NPT threads to maintain structural sealing. Ensure the probe gap is calibrated and verified using a static calibrator prior to locking the sleeve in place. Grounding must follow standard industrial instrumentation practices, ensuring electrical continuity between the housing and the machinery frame.
