Description

Product Overview

The Bently Nevada 21000-16-10-00-256-01-02 is a high-precision proximity probe housing assembly engineered for deep-reach machinery monitoring. This explosion-proof solution is designed for large-scale industrial assets, providing a secure interface for 8mm eddy current sensors. With its robust aluminum body and 304 stainless steel sleeve, it ensures reliable vibration and position data in hazardous Class I, Division 1 environments without requiring a machine shutdown for maintenance.

Technical Configuration

  • Model: 21000-16-10-00-256-01-02
  • Probe Option: 3300 XL 8mm Proximity Probe (16)
  • Cable Length: 1.0 Meter / 39 Inches (10)
  • Standoff: No Standoff Adapter Required (00)
  • Penetration Depth: 25.6 Inch / 650 mm (256)
  • Fittings: 1 Explosion-proof Fitting + Plug (01)
  • Mounting Thread: 3/4-14 NPT (02)

Technical Specifications

Adjustment Range ±0.5 inch (13 mm) Weight 1.1 kg (2.4 lbs)
Temperature -50°C to +80°C Materials Aluminum & 304 Stainless Steel
Compliance CSA Type 4, API 670, FCC Part 15, RoHS Certified

Installation & Maintenance

1. Resonance Mitigation: For the 21000-16-10-00-256-01-02, the 25.6-inch penetration depth makes sleeve support mandatory. This prevents probe stem resonance, which can cause signal noise or mechanical fatigue.

2. Gap Calibration: Set the probe gap to the standard -10.0 Vdc center-point. The housing allows for ±0.5" of mechanical adjustment to fine-tune the gap voltage after the assembly is mounted.

3. Space Requirements: Ensure a minimum of 17 inches of external clearance is available during installation to allow for proper cable routing and visibility of the serial number label for maintenance tracking.

Engineering Advantages

The Bently Nevada 21000 series excels in protecting proximity sensors from harsh process conditions. The combination of epoxy-coated aluminum and 304 stainless steel ensures resistance against corrosion and chemicals. Fully compliant with API 670 standards for external mounting, this assembly provides the structural integrity needed for critical vibration monitoring on large steam turbines and centrifugal compressors.

Technical FAQs

Q1: Is this model suitable for hazardous locations?
A1: Yes, it carries CSA certification for Class 1 Division 1 Groups C and D, making it safe for use in explosive atmospheres.
