Product Overview

The Bently Nevada 21000-16-05-00-019-03-02 is a ruggedized, explosion-proof aluminum housing assembly designed specifically for the 3300 XL 8mm proximity transducer system. This enclosure provides a secure external mounting point for proximity probes on industrial machinery, ensuring they remain protected from hazardous atmospheres and environmental contaminants. As a critical component of Turbine Supervisory Instrumentation (TSI), this housing allows for the precise measurement of vibration and shaft position while maintaining strict compliance with API 670 standards.

The 21000 series is engineered to facilitate easy probe adjustments and replacements without requiring the disassembly of the machine casing. This specific configuration features a 1.9-inch (48.26mm) sleeve and a 0.5-meter (20-inch) cable, making it an ideal choice for installations where clearance is limited but high-level protection is required.

Key Technical Characteristics

Built for long-term reliability in the most demanding industrial zones, this housing assembly incorporates several features to ensure measurement integrity.

• Explosion-Proof Certification: CSA Type 4 certified and rated for Class I, Division 1 hazardous areas, providing a safe solution for oil, gas, and chemical processing environments.

• Environmental Sealing: Utilizes a threaded dome cover and high-performance O-ring seals to prevent the ingress of moisture, oil, and dust, protecting the internal probe and connections.

• Versatile Cable Management: Equipped with a three-tier sealing system and a 3/4-14 to 1/2-14 NPT reducer, allowing for flexible field wiring and secure conduit integration.

• Precision Machined Components: The 1.9-inch probe sleeve is machined to tight tolerances, ensuring that the 8mm probe remains stable and accurately positioned relative to the target shaft.

• Extreme Temperature Rating: Engineered to maintain structural and sealing integrity across a wide thermal range, from -40°C to +120°C.
