Bently Nevada 330701-00-20-10-11-00 Compact Proximity Probe

Bently Nevada 330701-00-20-10-11-00 Proximity Probe

The Bently Nevada 330701-00-20-10-11-00 is a compact proximity transducer for 3300 XL systems. It features a short 2-inch overall case and an unthreaded design. The probe includes a 1.0-meter FluidLoc cable for moisture resistance. It uses a protected miniature coaxial ClickLoc connector. This model is built for reliable performance in space-constrained and demanding environments.

Frequently Asked Questions (FAQ)

Q: What is the advantage of the FluidLoc cable?

• A: The FluidLoc cable features a special jacket and sealant that prevent liquids from wicking along the cable core if the outer jacket is cut or damaged, protecting the signal integrity in wet or oily environments.

Q: Can this short probe be used for all measurement types?

• A: The 2-inch length is ideal for radial vibration. For axial position (thrust) measurement, ensure there is sufficient travel within the holder to cover the entire expected shaft movement without the probe body bottoming out.

Q: What does the "-11" option signify in the part number?

• A> The "-11" typically specifies the connector and cable type: a miniature coaxial ClickLoc connector with an attached protector and, in this case, the FluidLoc cable.
