Product Overview

Cable Design and Compatibility

The Bently Nevada 330730-080-02-CN is a 3300 XL 11 mm Extension Cable manufactured in the USA. Therefore, this cable connects the 3300 XL 11 mm probe to the Proximitor Sensor. The extension cable features a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. Consequently, it provides excellent signal integrity over long distances. All components of the transducer system use gold-plated brass ClickLoc connectors. As a result, these connectors lock into place and prevent loosening from vibration.

Patented Connection Technologies

The patented TipLoc molding method provides a robust bond between the probe tip and probe body. In addition, the CableLoc design securely attaches the probe cable to the probe tip. This design provides 330 N (75 lb) pull strength. Therefore, the 330730-080-02-CN offers exceptional mechanical reliability. The connector protector option provides additional protection in humid or moist environments. Consequently, connector protectors are recommended for all installations.

FluidLoc and Locknut Features

3300 XL probes and extension cables can also be ordered with a FluidLoc cable option. Therefore, this option prevents oil and other liquids from leaking out of the machine through the cable interior. Furthermore, the 3300 XL 11 mm probe comes standard with a locknut featuring pre-drilled safety wire holes. As a result, you can secure the probe against vibration loosening.

Connector Protection Notes

Silicone tape is also provided with each 3300 XL extension cable. Therefore, you can use silicone tape instead of connector protectors. However, silicone tape is not recommended where the probe-to-extension cable connection will be exposed to turbine oil. Consequently, use connector protectors for oil exposure applications.

Installation Guide

Follow these steps to install the Bently Nevada 330730-080-02-CN correctly.

1. Inspect Connectors: First, check that both ClickLoc connectors are clean and undamaged.

2. Align Connectors: Next, align the probe connector with the extension cable connector.

3. Push to Lock: Then, push the connectors together until the ClickLoc mechanism engages.

4. Verify Lock: After that, gently pull to confirm the connection is secure.

5. Apply Protectors: Meanwhile, install the connector protectors over the joined connectors.

6. Route Cable: Finally, route the 330730-080-02-CN away from heat sources and sharp edges.

The 330730-080-02-CN requires careful handling of the ClickLoc connectors. Therefore, do not twist or bend the connectors during mating. In addition, avoid exposing the connection point to turbine oil. Consequently, use connector protectors or silicone tape for environmental sealing.
