Frequently Asked Questions

• Is this 21000-34-05-20-065-04-02 certified for hazardous area use? Yes, the 3300 XL probe includes selectable hazardous area approvals, and the CSA-rated housing provides explosion-proof protection.
• What does the 2.0 in standoff adapter do for my installation? The 2.0 in standoff adapter extends the mounting distance, allowing proper probe positioning when the housing mounts farther from the machine.
• How does the 6.5 in probe penetration benefit my application? This 6.5 in penetration suits deeper bearing housings where standard probes would not reach the target surface.
• What does the 0.5 m probe cable length represent? The 0.5 m is the integral cable attached to the probe. You need a compatible extension cable to reach your monitoring system.
• Does the assembly include all necessary mounting hardware? It includes one 3/4-14 NPT plug and the 2.0 in standoff adapter. The housing body features threaded ports ready for your conduit connections.
• How do I set the correct gap with this reverse-mount design? With reverse-mount probes, the tip is not visible. You must set the gap using the precision 2.0 in standoff adapter and housing dimensions.
• What is your typical shipping timeframe for this item? We stock this item ready for immediate shipment. We typically dispatch orders within 5 days via FedEx, UPS, or DHL.
• Can I return this item if my requirements change? Yes, we accept returns within 30 days for unused items in their original factory packaging.
