Bently Nevada 330103-10-14-10-02-05 | 8mm Probe

Hazardous Area 8mm Probe with 100mm Tip and Full Approvals

The Bently Nevada 330103-10-14-10-02-05 belongs to the trusted 3300 XL series. We design this 8mm probe for accurate displacement and vibration measurements in explosive atmospheres. It carries CSA, ATEX, and IECEx approvals for hazardous locations worldwide. The 100mm unthreaded tip reaches through medium-depth housings before threads engage. The sensor operates within a 2mm (80 mils) linear range, starting at 0.25 mm from the target. For radial vibration monitoring, we recommend a gap setting of -9 Vdc, which equals approximately 1.27 mm.
