Description

Optimizing sensor protection in challenging industrial environments, the Bently Nevada 21000-28-05-00-024-03-02 serves as a ruggedized protective enclosure designed for proximity probes within machinery monitoring systems. This proximity probe housing assembly is engineered to safeguard delicate transducers from mechanical damage, process fluids, and harsh atmospheric exposure while facilitating safe, external probe adjustment and replacement without requiring a machine shutdown.

Constructed under the 21000 series copper-free aluminum housing specifications, this unit accommodates specific probe lengths, thread depths, and connection types as designated by its modular option codes. It provides a robust, sealed conduit connection and features integrated O-ring seals to prevent the ingress of dust, moisture, and corrosive agents into the machine casing, maintaining high system reliability in critical rotating machinery applications.

Features

• Robust copper-free aluminum housing construction offering exceptional corrosion resistance in harsh industrial environments.
• Dome-shaped cover design providing internal clearance for probe connectors, extension cables, and field wiring terminals.
• Facilitates safe and precise external adjustment of proximity probes relative to the target shaft.
• High-integrity O-ring seals to protect internal components from moisture, oil, and atmospheric contaminants.
• Dual conduit entries to streamline routing of field wiring and maintain clean cabling configurations.

Applications

• Steam and gas turbine vibration monitoring systems.
• Centrifugal and axial compressor casing protection.
• Hydroelectric generator shaft vibration and axial position measurements.
• Large industrial gearboxes, pumps, and fan monitoring setups.

Technical Specifications

Installation Guidelines

• Mounting: Thread the housing body securely into the machine case or bracket using the specified thread engagement. Use appropriate thread sealant to prevent process leaks.
• Sealing: Ensure all conduit entries are sealed with rated conduit plugs or cable glands to maintain the environmental IP/NEMA rating of the enclosure.
• Grounding: Connect the housing to the local structural ground in accordance with local electrical codes, especially when deployed in classified hazardous areas.
• Adjustment: Use the internal adjusting sleeve to set the correct probe gap (DC voltage offset) before locking the sleeve and securing the outer dome cover.
