The 330106-05-30-10-12-CN belongs to Bently Nevada's trusted 3300 XL series. This 8 mm reverse mount probe is specifically engineered for shaft vibration and axial position monitoring. It offers excellent linearity and stability over a wide temperature range. Consequently, it is a preferred choice for power generation, oil and gas, and heavy industry applications.
This model features an M10 x 1 thread and a total length of 1.0 meter (3.3 feet). The "CN" suffix denotes a country-specific agency approval, ensuring compliance with regional standards. Furthermore, the probe incorporates a FluidLoc cable option (identified by the -12 connector code). However, this option is generally unnecessary for most installations due to the built-in probe sleeve; therefore, we recommend evaluating your specific application before selecting it.
The probe's core performance relies on its precision engineering. Its nominal DC resistance from the center conductor to the outer conductor is 7.59 ± 0.50 Ω. This consistent resistance value ensures accurate signal transmission to the monitoring system. Additionally, the probe tip is constructed from Polyphenylene sulfide (PPS) , a material known for its excellent chemical resistance and dimensional stability. The probe case, meanwhile, is machined from AISI 303 or 304 stainless steel (SST) , providing robust protection against physical damage and corrosion.
The probe cable is a 75Ω triaxial design with fluoroethylene propylene (FEP) insulation. For applications requiring higher thermal resistance, an extended temperature range cable with perfluoroalkoxy (PFA) insulation is also available. The connector is made from gold-plated brass or beryllium copper, ensuring a secure and low-resistance connection. Specifically, this model uses a Miniature ClickLoc coaxial connector, which provides a reliable and vibration-proof coupling.
Understanding the mechanical limits is crucial for proper installation. The probe case thread is M10 x 1, with a maximum thread engagement of 15 mm. The tensile strength is rated at 330 N (75 lbf) from the probe case to the probe lead and 270 N (60 lbf) at the connector junction.
In terms of environmental resilience, the standard probe operates reliably between -52°C and +177°C (-62°F to +350°F) . Moreover, the extended temperature range probe supports tip temperatures up to +218°C (+425°F) and cable temperatures up to +260°C (+500°F). However, it is critical to note that exposing the probe to temperatures below –34°C (–30°F) may cause premature failure of the pressure seal. The probe also handles high humidity; it exhibits less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% relative humidity per IEC standard 68-2-3.
Proper installation of the 330106-05-30-10-12-CN ensures accurate readings and long service life. First, clean the mounting hole and threads thoroughly. Next, carefully thread the probe into the housing using the M10x1 thread. Remember that the maximum engagement is 15 mm; over-tightening can damage the threads or the internal components. Use a torque wrench to achieve the recommended seating torque. Additionally, the 3300 XL 8 mm probes are designed to seal differential pressure between the tip and case using a Viton® O-ring. While they are not pressure-tested before shipment, you can request a pressure seal test for your application directly from the custom design department.
Finally, route the cable carefully to avoid sharp bends and excessive strain. The FEP insulation provides good flexibility, but we suggest using the optional flexible stainless steel armor in high-abrasion areas. For optimal performance, pair this probe with a Bently Nevada extension cable and proximitor.
Your shipment for the Bently Nevada 330106-05-30-10-12-CN includes:
1 x 3300 XL 8 mm Reverse Mount Probe (1.0m cable)
1 x Miniature ClickLoc coaxial connector (attached)
Installation and mounting instruction sheet
1. What is the difference between the standard and FluidLoc cable options?
The FluidLoc cable option, indicated by the -12 connector code, provides additional sealing against fluid ingress. For most 330106 installations, however, the probe sleeve offers sufficient protection, so this option is rarely necessary.
2. Can I use this probe in a high-temperature steam turbine application?
Yes, the standard 330106-05-30-10-12-CN operates up to +177°C. For higher temperatures, please select an extended temperature range version with PFA cable insulation.
3. Is the probe compatible with other Bently Nevada monitoring systems?
Absolutely. This 8 mm reverse mount probe works seamlessly with the 3300 XL series extension cables and proximitors. Ensure all components are matched for proper calibration.
4. How do I verify the probe's health before installation?
You can measure the DC resistance between the center and outer conductors. For a 1.0-meter probe like this, the expected value is 7.59 ± 0.50 Ω. Any significant deviation may indicate a cable or connector fault.
5. What shipping methods are available for this item?
We ship all orders via FedEx, UPS, or DHL, depending on your location and preference. All packages are fully insured and tracked.
