Technical FAQs Answered

What does "with armor" mean for this probe?

It has a stainless steel sleeve over the cable at the probe body. This armor protects against abrasion, crushing, and physical damage in harsh locations.

Why is this 5-meter probe only for use with 5-meter Proximitors?

The system calibration is matched. Using a 5m probe with a different length sensor will cause incorrect vibration readings.

What is the electrical resistance for this 5-meter version?

The measured resistance from center to outer conductor is 7.2 Ohms, with a tolerance of plus or minus 0.8 Ohms.

Is the thread size different on armored probes?

In this case, yes. Model 330707-00-20-50-11-00 uses a 1/2-20 UNF thread, not the more common 5/8-18. Check your mounting hole.

Can the armored section be bent or adjusted?

No. The stainless steel armor is rigid. Only the flexible cable beyond the armor should be routed, respecting the 1-inch minimum bend radius.
