Bently Nevada 330106-05-30-20-12-CN 3300 XL Reverse Mount Probe

The Bently Nevada 330106-05-30-20-12-CN is a 3300 XL 8 mm reverse mount probe. This probe uses M10 x 1 threads for secure installation. You can use it for machinery vibration and position monitoring. It is made in the U.S.A. The reverse mount design suits tight installation spaces.

Technical Specifications of the 330106-05-30-20-12-CN

The Bently Nevada 330106-05-30-20-12-CN has a total length of 2.0 meters (6.6 feet). The connector option includes a Miniature ClickLoc coaxial connector with FluidLoc cable. The agency approval option is country specific (CN). The FluidLoc cable is not necessary for most installations due to the probe sleeve.

FluidLoc Cable Consideration

The FluidLoc cable option (code -12) is not needed for most 330105 and 330106 installations. The probe sleeve already provides adequate protection in typical applications. Consider your application carefully before ordering this option. Only select FluidLoc if your environment has specific fluid ingress risks.

Probe Construction

A Polyphenylene sulfide (PPS) tip forms the probe sensing face. The probe case uses AISI 303 or 304 stainless steel (SST). The tip material provides excellent chemical resistance. The stainless steel case ensures durability in harsh environments.

Electrical Specifications

The nominal probe DC resistance (RPROBE) measures 7.88 ± 0.50 Ω. This measurement goes from center conductor to outer conductor. The Bently Nevada 330106-05-30-20-12-CN uses a 75Ω triaxial standard cable. Fluoroethylene propylene (FEP) insulates the probe cable.

Mechanical Specifications

The probe case thread is M10 x 1 metric thread. The maximum length of thread engagement is 15 mm. This provides secure mounting in standard metric ports. The probe weight is 323 g per meter (11.4 oz per foot). For this 2.0m probe, the weight is approximately 646 g.

Temperature Range

The standard probe operates from -52°C to +177°C. Storage temperature follows the same range. Exposing the probe below -34°C may cause premature pressure seal failure. Always observe these temperature limits for reliable operation.

Pressure Sealing

The Bently Nevada 330106-05-30-20-12-CN uses a Viton O-ring for pressure sealing. This seals differential pressure between probe tip and case. Probes are not pressure tested before shipment. Contact the custom design department if you need pressure seal testing.

Humidity Performance

The probe experiences less than 3% change in Average Scale Factor (ASF). Testing followed IEC standard 68-2-3 at 93% humidity. The test duration ran for up to 56 days. This ensures reliable performance in humid environments.

Installation Guidelines for the 330106-05-30-20-12-CN

Mount the Bently Nevada 330106-05-30-20-12-CN using the M10 x 1 threads. Do not exceed 15 mm of thread engagement. Set the probe gap according to your 3300 XL system specifications. Hand-tighten the ClickLoc connector until locked. Only use the FluidLoc feature if your application requires it. Protect the probe from temperatures below -34°C. The 2.0m cable length allows flexible routing in large machinery.
