Professional FAQs

Cable & Length Selection

• Q: Why does the 9-meter probe have a higher resistance (8.5 ohms) than the 1-meter version (5.9 ohms)?
• A: The longer cable has more internal wire. This adds to the total electrical resistance measured from the tip to the connector. The monitoring system is calibrated to expect this value based on cable length.
• Q: Can I coil up the extra length if I don’t need the full 9 meters?
• A> Yes, but coiling must be done properly. Make large, loose coils (at least 12 inches in diameter). Do not make tight coils or kink the cable, as this can damage the internal wires.

Product Features

• Q: What is the advantage of a shorter 2.0-inch case length?
• A: A shorter case length is useful in applications with limited space behind the mounting point. It provides a more compact installation profile.
• Q: Is the FluidLoc cable suitable for outdoor use?
• A> Yes. The FluidLoc jacket is resistant to moisture, oils, and many chemicals. However, for direct burial or constant submersion, additional conduit or protection is recommended.

Practical Installation Tip

• Q: What is a key pre-installation check for the 5/8-18 thread?
• A> Always verify the tap depth and thread condition in your mounting hole. A damaged or shallow thread can prevent the probe from reaching the proper seating depth, affecting the measurement gap and potentially causing mechanical failure.
