Product Overview

The Bently Nevada 21000-16-05-15-037-01-02 is a ruggedized, explosion-proof proximity probe housing assembly designed for the most volatile industrial environments. This 21000-series model integrates a high-precision 3300 XL 8mm probe into a protective enclosure, making it the industry standard for chemical plants, refineries, and mining operations. Weighing approximately 1.1kg (without fittings), this assembly provides a secure, sealed interface for vibration and position monitoring in Class I, II, and III hazardous zones.

Technical Configuration

This configuration is optimized for deep-reach penetration and specialized hazardous-area mounting:

  • Full Model: 21000-16-05-15-037-01-02
  • Probe Type (16): Includes the reliable 3300 XL 8mm Proximity Probe.
  • Probe Cable Length (05): Compact 0.5 meter (20 inches) cable for local junction connectivity.
  • Standoff Adapter (15): Features a 1.5-inch adapter for precise probe gapping.
  • Probe Penetration (037): 307mm (12.1 inches) depth, ideal for large bearing housings.
  • Fittings Option (01): Includes explosion-proof fittings (3/4-14 NPT thread).
  • Mounting Thread (02): Standard 3/4-14 NPT industrial mounting.

Technical Specifications

Parameter Specification Detail
Housing Material Aluminum and Stainless Steel construction
Operating Temp Range -50°C to +80°C (-58°F to +176°F)
Enclosure Rating CSA Type 4 / Explosion-Proof
Compliance API 670 Standard compliant
Internal Probe 3300 XL 8 mm (75 Ω coaxial)

Installation & Maintenance

Safety is paramount when installing the 21000-16-05-15-037-01-02. For installations where probe penetration exceeds 12 inches (305mm), a sleeve support is critically recommended to prevent mechanical deflection or vibration-induced fatigue of the probe case. The assembly features a 3/4-14 NPT standard thread for mounting into the machine housing. Ensure all explosion-proof fittings are tightened to local electrical code specifications to maintain the CSA Type 4 rating and prevent moisture or gas ingress.

Engineering Advantages

The primary advantage of the Bently Nevada 21000 series is its Dual-Layer Protection. Not only does the external aluminum/stainless steel housing provide a fire-safe barrier, but the internal 3300 XL probe offers the gold-standard in eddy current measurement accuracy. The assembly includes a flag label for easy identification of probe details in the field, and the compact 0.5m cable minimizes signal noise in tight spaces. Its wide temperature rating (-50°C to +80°C) ensures reliable operation in both sub-zero arctic mining and high-heat chemical processing environments.

Technical FAQs

Q1: Is the internal probe replaceable?
A1: Yes, the internal 3300 XL 8mm probe can be replaced or serviced without necessarily discarding the entire explosion-proof housing, provided the integrity of the enclosure remains intact.

Q2: What does "307mm penetration" refer to?
A2: This is the length from the mounting face of the housing to the tip of the probe, indicating how far the probe extends into the machine to reach the target shaft.

Q3: Does this housing meet offshore requirements?
A3: While it is CSA and Explosion-Proof rated, please verify specific maritime certifications (like ABS or DNV) if using on offshore platforms, though it is frequently used in similar onshore hazardous zones.
