Expert FAQ & Selection Guide

What does “probe penetration 13.5 inches” mean?

It is the maximum distance the probe tip can extend from the housing mounting face. This allows you to adjust how close the probe is to the machine shaft you are measuring.

Why is the cable only 0.5 meters long?

This housing is designed for the probe cable to immediately enter a sealed conduit system. The short cable connects to a nearby junction box, not directly to a distant monitor.

When do I need this explosion-proof housing?

You need it when installing a probe in a classified hazardous location (e.g., Zone 1, Division 1). The standard probe alone is not safe for such areas.

What is the difference between 21000 (Aluminum) and 24701 (Stainless Steel) housings?

The 21000 has an aluminum body, which is lighter and corrosion-resistant. The 24701 has a full stainless steel body for more corrosive environments or where specified.

Does the “03” fitting kit include everything I need to seal the cables?

Yes. It includes plugs, a pipe reducer, and a cable grip seal with multiple grommet sizes to fit different cable diameters from 1/8 to 3/8 inches.
