Description
Product Overview
The Bently Nevada 21000-28-05-00-050-03-02 is an API 670 compliant Explosion-Proof Proximity Probe Housing Assembly engineered for rotating machinery vibration tracking in hazardous locations. Constructed from high-strength aluminum with a 304 stainless steel sleeve, this external housing unit includes an integrated 3300 XL 8mm reverse-mount proximity probe with a 0.5m cable and a 5-inch penetration length. Weighing approximately 1.1 kg (2.4 lbs), it provides CSA Type 4 environmental sealing and explosion-proof containment for critical turbo-machinery monitoring.
Core Technical Advantages
API 670 Compliant Enclosure: Fully certified as a CSA Type 4 housing meeting stringent American Petroleum Institute (API) 670 standards for externally mounted probe assemblies.
Integrated 3300 XL Sensing Hardware: Features an integrated 3300 XL 8mm probe configured for reverse mounting with 0.5m cable length, delivering sub-micron eddy-current vibration accuracy.
Comprehensive Hazardous Area Ratings: Certified by CSA for Class I Div 1/2 (Groups C, D) and Class II Div 1/2 (Groups E, F, G) explosion-proof operation in harsh petrochemical environments.

Installation and Maintenance
Mounting & Threading: Thread the 3/4-14 NPT mounting base directly into the machine casing or mounting bracket. Tighten securely and verify the O-ring seals prevent process gas or liquid ingress.
Conduit & Cable Seal: Install the provided cable seal grip grommet matching your extension cable diameter (1/8", 1/4", or 5/16"). Screw the dome cover completely onto the body to preserve CSA Type 4 rating.
Engineering Advantages
Standardized API 670 Field Installation
Designed specifically to satisfy API 670 guidelines, this housing assembly provides field engineers with a standardized, robust method for mounting proximity probes on turbines, compressors, and large pumps without custom machining.
Complete Environmental & Explosion Protection
The combination of a heavy-duty aluminum body, threaded dome cover, and sealed conduit fittings protects inner sensing elements against moisture, corrosive atmospheric gases, and extreme ambient industrial shock.
Pre-Configured Modular Components
All core installation hardware—including the internal reverse-mount probe, sleeve, thread seals, and cable strain-relief grips—arrives as a factory-tested assembly, streamlining field setup time.
