- Aids in diagnosing rotor rub, mechanical looseness, and severe oil whip conditions early.
Global PLC Spare HUB's Insight
Our technical team installed the 21000-16-05-15-114-03-02 on a high-pressure refinery gas compressor. We found that utilizing the 1.5-inch standoff adapter successfully eliminated thermal radiation transfer from the hot machine casing to the internal probe tip. When configuring penetrations exceeding 12 inches, always install intermediate sleeve supports to suppress harmonic resonance.
Model Comparison and Selection Guide
| Model Number | Standoff Option | Penetration Depth | Selection Guidance |
|---|---|---|---|
| 21000-16-05-15-114-03-02 (Current Product) | 1.5 in (38 mm) | 11.4 in | Ideal for deep machine casing penetrations requiring thermal standoffs. |
| 21000-28-00-00-039-03-02 | 0.0 in (None) | 3.9 in | Shorter profile configuration designed for direct surface mounting. |
Frequently Asked Questions
Question: Why must I counterbore the machine case for certain probe penetration lengths?
Answer: Counterboring prevents unwanted side-view or rear-view proximity signal reflections when using penetration depths between 1.0 and 2.0 inches.
Question: How do I handle probe serial number tracking when the cable is concealed inside the sleeve?
Answer: For configuration combinations where the main cable is hidden, the factory prints the part number and serial number on an exterior flag label.
Question: What precautions are necessary for penetrations greater than 300 mm?
Answer: You must add a mechanical sleeve support near the probe tip to prevent high-frequency vibration resonance from damaging the probe structure.
Question: Can this aluminum housing withstand corrosive chemical plant atmospheres?
Answer: The aluminum body features a protective 304 stainless steel sleeve, but you should verify external chemical exposure limits against standard aluminum corrosion charts.
Question: How should technicians select the correct cable gland grommet size during installation?
Answer: Measure your external field conduit cable outer diameter accurately and match it to one of the three supplied grommet ranges (1/8-3/16, 1/4-5/16, or 5/16-3/8 inches).
