Frequently Asked Questions (FAQ)

What does "with armor" mean for this probe?

• The armor is a flexible metal braid or sleeve over the cable. It provides extra protection against abrasion, crush damage, and cutting in tough plant environments.

Can I use this 5-meter probe with a different length Proximitor?

• No. The product data states this 330104 model is designed for use with the 5-meter Proximitor sensor only. Using mismatched components affects system accuracy.

What is the advantage of the M10 x 1 thread?

• The M10 x 1 metric thread is a common international standard. It often simplifies installation in machinery designed with metric mounting holes.

What do the temperature codes T1, T2, T3 etc. mean?

• These codes show the maximum surface temperature the device can reach. T1 is the highest (up to 450°C), T6 is the lowest. Your area classification dictates the required T-code.

Is the pressure seal tested before shipping?

• Standard probes are not pressure tested prior to shipment. The design incorporates a Viton® O-ring for sealing. Contact Bently Nevada for custom testing if your application requires it.
