Features and benefits
The Bently Nevada 21000-16-10-00-103-04-02 Housing Assembly provides secure and stable mounting for 3300 series proximity probes. It protects probes from dust, moisture, and vibration, ensuring reliable and accurate shaft position and vibration measurements. Easy to install and compatible with standard 8 mm probes, it enhances monitoring accuracy, simplifies maintenance, and supports long-term performance in demanding industrial machinery environments.
Specific Application
External mounting and explosion-proof containment for proximity probes tracking radial shaft vibration on hazardous rotating machinery.
Target displacement tracking where a sleeve penetration depth of 10.3 inches is required without structural counter-boring.
Protection of internal sensor elements and cabling connection points in hazardous environments demanding CSA Type 4 rated housing certifications.
System Compatibility and Alternative Models
System Compatibility: Contains an integrated 3300 XL 8mm reverse-mount proximity probe with a 1.0-meter cable length. It interfaces directly with Bently Nevada 3300 XL Proximitor Sensors, 3300 XL Extension Cables, and machinery protection architectures like the 3500 rack system.
Alternative Model: 24701-16-10-00-103-04-02 Proximity Probe Housing Assembly.
Key Differences:
Casing Material: The 21000 model utilizes a lightweight aluminum body with a 304 stainless steel sleeve, whereas the 24701 version relies entirely on a ruggedized 303 stainless steel main housing structure.
Weight Metrics: The 21000 aluminum variant features a typical unmounted mass of 1.1 kg (2.4 lb), whereas the 24701 stainless steel assembly is notably heavier at 1.8 kg (4.1 lb).
