Technical FAQ
Q: Minimum detectable vibration level?
A: 0.004 mm/s rms noise floor (4.5Hz-5kHz bandwidth).
Q: Suitable for submerged applications?
A: Hermetically sealed for 100% humidity but not submergence - avoid direct liquid contact.
Q: Difference between UNC and UNF threading?
A: UNC (Unified National Coarse) has wider thread spacing than UNF - preferred for high-vibration environments.
