Technical FAQ

• Q: What is the practical difference between a 30mm and 40mm case?
• A: The 30mm case is 10mm shorter. This can be critical when mounting in very shallow bearing housings or where physical obstructions limit space directly behind the probe.
• Q: Are there special considerations for setting the gap with such a short probe?
• A: The gap setting procedure is the same. However, with less probe body behind the mounting nut, ensure you have proper tool clearance to adjust and tighten the probe to the correct gap and torque.
• Q: Does the “Multiple Approvals” option cover both gas and dust atmospheres?
• A: The “05” option typically includes approvals for use in explosive gas atmospheres (ATEX/IECEx). For specific dust atmosphere (Zone 21/22) approvals, please contact us with your exact requirement.
• Q: Can I order this model with a different cable length?
• A: The 330709 probe comes in standard 1, 5, or 9-meter lengths. This specific configuration (030-50-11-05) is a 5-meter version. We stock various lengths; contact us for other options.
• Q: What is your process for warranty and delivery of certified parts?
• A> All certified probes like the 330709-000-030-50-11-05 come with a full 12-month warranty. We ship using reliable carriers (DHL, FedEx, UPS) to ensure timely, trackable delivery to your project site.
