- Cable Specification: 75-ohm triaxial with low-loss FEP insulation.
Expert FAQ for Long-Cable Applications
- Q: Why is the resistance different for a 9-meter probe? A: The longer cable adds natural resistance. The monitoring system is calibrated to compensate for this specific value.
- Q: Can I coil the excess cable length? A: Yes, but coil it loosely with a diameter greater than 2 inches to avoid kinking and signal issues.
- Q: Is this probe suitable for outdoor or submerged use? A: The FEP cable is moisture-resistant, but the connectors are not waterproof. Protect connections from direct weather or liquids.
- Q: What happens if I use a 9m probe with a 1m system? A: The readings will be incorrect. You must use a proximitor card calibrated for the matching cable length.
- Q: How do I manage the heavier cable over a long run? A: Use adequate cable clamps and supports every 1-1.5 meters to prevent strain on the probe thread and connector.
