Technical Support & Frequently Asked Questions

• Q: What is the main use for this probe configuration? A: It is the default choice for general-purpose, short-distance vibration and position measurement.
• Q: Does the lack of agency approvals limit its use? A: No. It is perfect for standard industrial plants where specific hazardous location certifications are not mandatory.
• Q: Can I use this probe with a metric threaded mount? A: Not directly. The 5/8-18 UNF thread requires the correct mounting boss or an adapter.
• Q: How does temperature affect the probe's output? A: The system has built-in temperature compensation to maintain accuracy across its rated range.
• Q: What if I need a pressure test certificate for the O-ring seal? A: Contact us. We can facilitate custom testing through Bently Nevada for critical applications.
