Technical Specifications Matrix
- Manufacturer & Model: Bently Nevada 21000-16-05-15-072-03-02
- Body Construction: Aluminum housing body with 304 stainless steel sleeve
- Assembly Mass: Approximately 1.1 kg (2.4 lb) typical weight without conduit fittings
- Penetration Limits: Combined C plus D penetration reaches up to 17.0 inches with visible flag label
- Electrical Compliance: FCC Part 15 subpart B compliant and RoHS Directive 2011/65/EU certified
- Hazardous Approvals: CSA explosion-proof certified for Class I, Div 1/2 and Class II environments
Compatible Rotating Equipment & Application Scenarios
The 21000-16-05-15-072-03-02 assembly integrates directly with API 670 compliant machinery protection systems. Typical high-reliability industrial deployment environments include:
- Large steam turbines and gas expansion compressors requiring exact radial vibration tracking.
- Heavy-duty centrifugal pumps operating in hazardous refinery processing zones.
- Multistage industrial blowers and heavy gearboxes monitored by eddy-current transducers.
Advanced Diagnostic Capabilities
The assembly design allows vibration analysts to measure shaft dynamic motion and axial position with sub-micron resolution. Early detection of rotor unbalance, oil whirl, and shaft rub prevents catastrophic machinery failure. The robust housing shields sensitive high-frequency signals from severe electromagnetic interference in plant environments.

Global PLC Spare HUB's Insight
Machinery engineers often encounter high-frequency resonance issues when installing extended probe penetrations on high-speed turbines. Field experience shows that adding intermediate sleeve supports when combined penetration depths exceed 12 inches completely eliminates false vibration spikes. For instance, a Gulf Coast refinery stabilized its critical compressor monitoring network by replacing rigid unanchored probes with the robust 21000-16-05-15-072-03-02 housing assembly, ensuring uninterrupted API 670 compliance.
Model Selection & Technical Comparison Guide
Evaluating alternative housing configurations ensures optimal mechanical fit for your specific machine case clearance. Review the technical comparison below:
| Model Number | Probe & Cable Option | Penetration Depth | Engineering Recommendation |
|---|---|---|---|
| 21000-16-05-15-072-03-02 (Current Model) | 3300 XL 8 mm (0.5 m cable) | 7.2 inches total penetration | Optimal for deep-set machine case penetrations requiring CSA explosion-proof enclosures. |
| 21000-28-10-15-030-04-02 | Alternative Probe Option | Shorter penetration variant | Recommended for shallow mounting cases with restricted radial installation clearances. |
Professional Frequently Asked Questions
Question: Why must instrument technicians verify counter-boring requirements on machine cases when installing the 21000-16-05-15-072-03-02?
Answer: For probe penetration lengths between 1.0 and 2.0 inches, counter-boring prevents housing side-view or rear-view interference effects from distorting eddy-current signals.
Question: How does the CSA Type 4 enclosure rating impact outdoor compressor installations?
Answer: The Type 4 rating ensures complete protection against windblown dust, rain, and hose-directed water ingress in exposed offshore platform environments.
Question: What specific precaution applies when probe penetration lengths exceed 300 mm (12 in)?
Answer: Installers must add rigid sleeve support near the probe tip to prevent harmonic resonance from damaging the internal mechanical structure.
Question: Can maintenance personnel access the probe serial number once the housing is fully mounted?
Answer: Yes, probe part numbers and serial numbers are displayed on an external flag label secured to the visible section of the probe cable.
Question: What thread sealant specification is required for the 3/4-14 NPT conduit entries?
Answer: Technicians must apply a certified non-hardening thread lubricant compliant with hazardous area explosion-proof installation codes.
