Applications
The Bently Nevada 330106-05-30-20-12-05 probe excels in harsh industrial environments where accurate displacement measurement is critical. Its M10x1 threads and 15 mm maximum thread engagement allow secure mounting in tight spaces. Typical applications include:
- Radial vibration monitoring on steam and gas turbines
- Axial position measurement on compressors
- Keyphasor reference for speed and phase measurement
With CSA, ATEX, and IECEx approvals, this probe is suitable for hazardous area installations. PLC Source PRO offers fast quote response and technical support to ensure you select the right probe for your machinery protection system.
Installation and Maintenance
Proper installation is essential for optimal performance. Use the M10x1 threads to mount the probe, ensuring thread engagement does not exceed 15 mm. The reverse mount design allows the probe to be installed from the back of the machine casing, simplifying setup. The FluidLoc cable option provides additional protection against fluid ingress, but Bently Nevada notes it is not necessary for most 330105 and 330106 installations due to the probe sleeve. Consider the application carefully before ordering FluidLoc. For maintenance, periodically check the probe DC resistance (7.88 ± 0.50 Ω at 2.0 m) and inspect the connector for contamination. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure.
Compatibility and Selection Guide
The 330106-05-30-20-12-05 is compatible with 3300 XL series extension cables and proximitor modules. When selecting a probe, consider total length, connector type, and agency approvals. The miniature ClickLoc coaxial connector ensures secure and reliable signal transmission. For extended temperature range applications, choose the PFA insulated cable option.
