Frequently Asked Questions (FAQ)

What is the main use of this probe?

It measures vibration and position on rotating machinery shafts for protection systems.

Can I use a 1-meter proximitor with this 5-meter probe?

No. You must pair it with a matching 5-meter 3300 XL Proximitor sensor for correct calibration.

The installation instructions show two torque values (63.3 and 21.1 N•m). Which one is correct?

Use 21.1 N•m. The higher value is for a different, armored probe variant. Overtightening can damage the case.

My machine room gets very cold. Is this a problem?

The probe works down to -52°C. But temperatures below -34°C can damage the internal pressure seal. Consider a heated enclosure.

Can I trim the cable if it is too long?

No. Cutting the cable will change its electrical characteristics. It will make the entire probe assembly unusable.

From experience, what is the most common installation mistake?

Overtightening the connector. It only needs to be finger-tight. Using a wrench often breaks the connector latch.

How do I know if the probe is working after installation?

Check the gap voltage on your monitor. A stable voltage within the specified range confirms a good installation and target.
