Frequently Asked Questions (FAQ)

Why choose an 8 mm probe over a 5 mm probe?

• The 8 mm 3300 XL probe has a thicker encapsulation and stronger case. It provides better protection against physical damage in tough environments.

What do the numbers in the model suffix mean?

• Each pair of numbers specifies a key feature. For example, "10" always means a 1.0-meter system length for this Bently Nevada probe model.

Is this probe suitable for wet or oily locations?

• Yes. The "12" option in this model number means it has a FluidLoc cable. This design stops oil from traveling inside the cable.

What is the correct gap setting for installation?

• For measuring radial vibration, adjust the probe to output about -9 Vdc. This is roughly a 1.27 mm (50 mil) gap from the target.

Does the probe include a calibration certificate?

• A standard Certificate of Origin (COO) is available if requested. The product ships without a full calibration certificate unless ordered specially.
