Installation Guidelines
- Ensure the probe lead is longer than the sleeve length to prevent mechanical stress.
- For sleeve lengths exceeding 304 mm (12 inches), utilize additional sleeve support to mitigate vibration-induced fatigue.
- Verify that the hazardous area classification of the installation site matches the rating of the housing assembly.
- Ensure all NPT threads are properly sealed to maintain the integrity of the explosion-proof enclosure.
- Handle with care to avoid damage to the probe tip or connector protector during installation.
