Description
Product Overview
The Bently Nevada 21000-28-05-00-076-04-02 is an API 670 compliant Explosion-Proof Proximity Probe Housing Assembly engineered for deep-access rotating machinery vibration monitoring in extreme environments. Constructed from high-strength aluminum with a 304 stainless steel sleeve, this rugged external housing integrates a 3300 XL 8mm reverse-mount proximity probe with a 0.5m cable and an extended 7.6-inch (193 mm) penetration depth. Weighing approximately 1.1 kg (2.4 lbs), it provides CSA Type 4 weather-proofing and explosion-proof containment for critical turbines, compressors, and petrochemical reactors.
Core Technical Advantages
Extended 7.6" Penetration Reach: Specifically designed for deep-access machine casings, ensuring precise proximity probe positioning in complex machinery setups.
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.
Comprehensive Hazardous Area Ratings: Certified by CSA for Class I/II/III explosion-proof operation, supporting extreme operating temperatures from -50°C to +80°C.
