Installation Guidelines
- Ensure the probe lead is longer than the sleeve length during installation.
- For sleeve lengths exceeding 304 mm (12 inches), additional mechanical support is required to mitigate vibration-induced fatigue.
- Verify that all O-rings and thread seals are properly seated to maintain the environmental seal against moisture and contaminants.
- Always power down the associated monitoring system before installing or removing probe assemblies to prevent electrical faults.
- Ensure the conduit connection is properly sealed to maintain the explosion-proof integrity of the housing.
FAQ
What is the primary function of the 21000 series housing?
The 21000 housing provides essential mechanical and environmental protection for proximity probes, ensuring accurate data collection for radial vibration and axial position monitoring in rotating machinery.
Is this housing suitable for hazardous locations?
Yes, the 21000 aluminum housing is certified as explosion-proof for hazardous areas (Class I, Div 1 & 2, Groups C and D) and meets CSA Type 4 enclosure requirements.
What is required for probe penetrations less than 1.0 inch?
For applications requiring a probe penetration of less than 25 mm (1.0 in), a separate 21003-020 individual standoff adapter is typically required.
