Frequently Asked Questions (FAQs)
Q1: Is this probe compatible with older 3300 series components?
Yes, it is fully backward compatible with non-XL 3300 5 mm and 8 mm systems.
Q2: What is the primary use of this probe?
It is used for measuring shaft vibration and position in rotating machinery.
Q3: Can the probe be installed in hazardous areas?
Yes, it carries CSA, ATEX, and IECEx approvals for hazardous environments.
Q4: Does the probe require field calibration?
No, components are factory-matched and do not require field calibration.
Q5: What is the recommended gap setting?
Approximately 1.27 mm (50 mils), equivalent to –9 Vdc.
Q6: Can the probe withstand high temperatures?
Yes, the extended temperature range version handles up to +218°C.
Q7: Is the probe resistant to oil leaks?
