The Bently Nevada 330171-15-30-10-02-05 is a 3300 5 mm Proximity Probe designed for non-contact measurement of shaft vibration, axial position, Keyphasor® (speed/reference), and other rotating machinery parameters. It is part of the 3300 5 mm Proximity Transducer System, which consists of a 3300 5 mm probe, a 3300 XL extension cable, and a 3300 XL Proximitor® Sensor. When used together, the system provides a voltage output proportional to the distance between the probe tip and the conductive target.

Frequently Asked Questions
What does the "15" option represent?
It specifies a 1.5-inch unthreaded length.
What does the "30" option represent?
It specifies a 3.0-inch overall probe case length.
What does the "10" option indicate?
It specifies a 1.0-meter (3.3-foot) total system length.
What is connector option "02"?
A miniature coaxial ClickLoc® connector with standard cable.
What does approval option "05" mean?
It indicates the probe has multiple hazardous-area approvals (such as CSA, ATEX, and IECEx, depending on the certification guide).
