Frequently Asked Questions (FAQ)

What is the main benefit of the armored probe (330102 vs. 330101)?

The armored version has a strong metal sleeve over the unthreaded body. It protects against impact, abrasion, and crush damage in harsh environments like large gearboxes or mills.

Can I use this 1-meter probe to make a 5-meter system?

Yes. This 1-meter probe is designed to connect with a 3300 XL 5-meter Proximitor sensor. Together, they create a standard 5-meter system for optimal signal integrity.

What does "Intrinsically Safe (ia)" mean for this probe?

It means the probe can be used in explosive atmospheres (Zone 0) when connected with a certified intrinsic safety barrier. The barrier limits electrical energy to prevent ignition.

Is the probe body pressure-rated?

The probe has a Viton® O-ring seal to handle differential pressure between the tip and case. For a specific pressure test, you must contact the factory's custom design department before ordering.

Why is thread engagement limited to 0.563 inches?

This is the maximum safe length. Over-tightening can damage the probe's internal pressure seal. Always use a torque wrench and follow installation guidelines.
