Common Installation Questions

What does the Ex i certification mean for installation?

This rating allows safe use in explosive atmospheres where flammable gases or dust may be present, without risk of ignition.

Why use a short integral cable with separate extension?

This design allows replacement of damaged extension cables without changing the entire sensor, saving time and cost.

What machinery typically uses 3/8-24UNF threading?

This thread size is standard in many industrial applications, particularly in North American machinery and OEM equipment.

How does the two-part cable system affect signal quality?

Properly connected, the system maintains excellent signal integrity up to the full 20 kHz frequency range for accurate vibration data.

Can this 111-412 sensor monitor both vibration and position?

Yes, it simultaneously tracks shaft vibration levels and positional changes like thrust position or radial clearance.
