Bently Nevada 330106-05-30-90-12-CN 3300 XL Reverse Mount Probe with FluidLoc Cable & Country Specific Approval

The Bently Nevada 330106-05-30-90-12-CN is a 3300 XL 8 mm reverse mount probe. This unit uses M10 x 1 threads for straightforward installation. You can use it for non-contact shaft vibration monitoring in regulated markets. The probe is made in the U.S.A. As a result, it delivers reliable performance for machinery protection systems requiring both country specific certifications and specialized cable protection.

Technical Specifications of the 330106-05-30-90-12-CN

The Bently Nevada 330106-05-30-90-12-CN has a total length of 9.0 meters (29.5 feet). This is the maximum standard cable length available for this probe series. The connector option is a miniature ClickLoc coaxial connector with FluidLoc cable. Agency approval option CN indicates country specific certifications. Additionally, the nominal probe DC resistance (RPROBE) is 9.87 ± 0.50 Ω. Specifically, this resistance is measured from the center conductor to the outer conductor. The higher resistance reflects the maximum 9.0 meter cable length.

Country Specific Approval

The Bently Nevada 330106-05-30-90-12-CN carries approvals tailored to specific national regulations. Contact Bently Nevada for the exact list of countries covered by this approval code. This option provides flexibility for installations in markets with unique certification requirements. The 9.0 meter length allows maximal separation between probe tip and monitoring electronics.

Important Note About FluidLoc Cable

The FluidLoc cable option (–12) is not necessary on the vast majority of 330105 and 330106 installations. This is due to the presence of the probe sleeve which provides adequate environmental protection. Therefore, consider your application carefully before ordering the FluidLoc cable option for these probes. For most standard industrial installations, the standard cable option is sufficient and more cost-effective.

Extended Cable Length Considerations

The 9.0 meter length of the Bently Nevada 330106-05-30-90-12-CN allows maximal separation between probe tip and monitoring electronics. This is particularly useful when the proximity sensor must be located far from the control cabinet. However, note the higher DC resistance of 9.87 Ω due to the longer cable run. For most applications, this remains well within acceptable limits for proper operation.

Probe Construction Materials

The probe tip consists of Polyphenylene Sulfide (PPS) material. For durability, the Bently Nevada 330106-05-30-90-12-CN has a case made of AISI 303 or 304 stainless steel. The standard cable is 75Ω triaxial type. Furthermore, the cable insulation uses fluoroethylene propylene (FEP). For extended temperature ranges, PFA insulation is available as an alternative. Consequently, optional armor uses flexible AISI 302 or 304 SST with an FEP jacket.

Mechanical Specifications

The probe case thread is M10 x 1. Therefore, the maximum length of thread engagement is 15 mm. The Bently Nevada 330106-05-30-90-12-CN weight is 323 g per meter (11.4 oz per meter). As a result, the total probe weight is approximately 2,907 g (6.41 lbs) for the 9.0 meter length. This is the heaviest standard configuration in the reverse mount probe family. Moreover, the maximum rated tensile strength from the probe case to the probe lead is 330 N (75 lbf). In addition, the tensile strength at the probe lead to extension cable connectors is 270 N (60 lbf). Finally, the connector material consists of gold-plated brass or gold-plated beryllium copper.

Temperature Range

The standard probe operates from -52°C to +177°C. Nevertheless, extended temperature range probes reach +218°C at the tip. Extended range cables handle -51°C to +260°C. However, exposing the probe to temperatures below -34°C may cause premature failure of the pressure seal.

Pressure and Humidity Ratings

The Bently Nevada 330106-05-30-90-12-CN uses a Viton® O-ring for pressure sealing. Accordingly, the seal prevents differential pressure between the tip and case. Probes are not pressure tested before shipment. For this reason, contact the custom design department if you require a pressure seal test.

Humidity testing shows less than a 3% change in Average Scale Factor (ASF). For instance, testing followed IEC standard 68-2-3 at 93% humidity for up to 56 days. Thus, the probe maintains stable performance in high-humidity environments.

Installation Guidelines for the 330106-05-30-90-12-CN

To begin, mount the Bently Nevada 330106-05-30-90-12-CN using M10 x 1 threads. Do not exceed 15 mm of thread engagement. Then, hand-tighten the miniature ClickLoc connector until it locks. Keep the probe tip clean for accurate measurements. Use the recommended gap setting for your specific application. Additionally, follow all country specific approval requirements for your target market. Remember that the FluidLoc cable option is only necessary for specialized applications requiring additional fluid protection. The 9.0 meter cable requires careful routing to avoid damage. Support the cable at regular intervals to prevent stress on the connectors.
