Diagnostic Capability & FAQ

This probe provides a vital gap voltage signal. Monitoring this DC voltage helps diagnose:

– Relative shaft position and dynamic motion.

– Probe health and proper gap setting.

– Early signs of machine misalignment or bearing issues.

Frequently Asked Questions

• Q: What is the main difference between 8mm and 11mm probes?
• A: The 11mm probe has a larger tip. It requires a larger minimum target surface. It often provides a stronger signal in its linear range. Choose based on your shaft size and system requirements. Compare with 8mm probes here.
• Q: Can I cut and re-terminate the cable if it’s too long?
• A: No. The probe and cable are a sealed, tuned unit. Cutting the cable will change the electrical characteristics and make readings inaccurate. Always order the correct pre-set length.
• Q: My environment has high humidity and occasional fluid spray. Is this probe suitable?
• A: Yes. The FluidLoc cable and sealed ClickLoc connector are specifically designed to resist moisture and fluids, making it a robust choice for such conditions.
• Q: How do I select the right temperature class option?
• A: Match the probe’s T-class to your area’s hazardous classification requirements. The standard model covers a broad range, but consult your safety engineer for the specific code needed for your plant.

Quick Selection Guide

• For Large Shafts (>150mm): This 11mm probe is the recommended choice.
• For Standard-Size Shafts: Check if an 8mm probe might be more suitable for your application.
• Check Your Thread: Verify your mounting hole is M16x1.5.
• Measure Cable Run: Order the 9.0m length (or other standard length) that reaches your monitor without stretching.
• Confirm Connector Type: Ensure your system uses the miniature ClickLoc style.
