Frequently Asked Questions (FAQ)

Technical & Application

• What is the main difference between this 3300 NSv probe and the old 3300 RAM probe?
• The NSv probe has higher chemical resistance. It is better for harsh environments like chemical or process compressors. It also has superior side-view characteristics.
• What should I consider for axial position measurement on targets smaller than 13mm in diameter?
• Small shaft diameters can change the scale factor. Reduce the gap between probe and target to limit this effect. Refer to the calibration curves in the manual.

Installation & Commissioning

• What is the correct installation torque for the M8 threaded probe?
• Recommended torque is 5.1 N•m (45 in•lb). Maximum is 7.3 N•m (65 in•lb). “Finger tight” is often sufficient. Avoid over-tightening to prevent damage.
• Is the probe’s pressure seal factory tested?
• No, standard probes are not factory pressure tested. If your application requires certified pressure sealing, contact the manufacturer for custom testing.

Selection Guide

• How do I choose the correct probe cable length for my machine?
• Choose based on the actual distance from the mounting point to the junction box or proximitor. Allow some slack for routing, but avoid excessive length to prevent signal issues. Common lengths are 0.5m, 1m, 5m, and 9m.

Buyer’s Checklist

• Confirm your monitoring system (e.g., 3300 XL NSv) is compatible with this probe.
• Verify the mounting thread on your equipment is M8x1.
• Check if the 0.5m cable length is sufficient for your wiring distance.
• Evaluate if the operating environment has chemicals to benefit from NSv’s resistance.
• Have the correct ClickLoc mating connector and tool ready.
