Description

The Bently Nevada 330130-040-12-CN, also cataloged under the 330130 product series, operates as a high-reliability hardware component for eddy-current signal transmission within 3300 XL 8 mm Proximity Transducer System platforms. This specialized cable anchors the vital electrical bridge between the proximity probe tip and the Proximitor signal-conditioning sensor.

Hardware Specifications

Eddy-Current Transmission and Design Characteristics

The hardware utilizes a 75 $\Omega$ triaxial physical profile to route the high-frequency radio frequency (RF) signal from the Proximitor sensor down to the probe tip without signal attenuation. Because the system depends on exact electrical lengths, the 4.0-metre cable matches specifically with a 1.0-metre proximity probe to create a balanced 5.0-metre total system length loop.

Meanwhile, the patented CableLoc™ internal strain relief gives the assembly a rugged 330 N (75 lbf) maximum pull strength, actively preventing core separation under heavy industrial vibration. Furthermore, the FluidLoc® configuration (-12) integrates an internal barrier substance that blocks oils, cooling fluids, or process gases from wicking through the cable core into the terminal enclosure if the probe casing suffers mechanical damage.

Frequently Asked Questions

Q: What does the “CN” suffix signify regarding field applications?

A: The “CN” suffix indicates compliance and factory labeling certifications for regional hazardous area standards, specifically satisfying Chinese NEPSI marking requirements alongside global ATEX/IECEx options.

Q: Can operators substitute standard silicone tape for the factory-installed connector protectors on this cable?

A: No. While standard uninsulated cables allow silicone tape wrapping, the -12 option incorporates permanent, rigid mechanical connector protectors that actively isolate the gold ClickLoc® joints from fluid ingress and accidental grounding against the machine body.

Field Installation Guidelines

• Inspect the gold-plated brass ClickLoc® miniature connectors for debris, grease, or copper oxidation before attempting the final physical connection.
• Next, push the male and female connector halves together, turning them firmly until the internal spring mechanism clicks into place.
• Slide the integrated connector protector sleeve fully over the joined terminal cluster to seal out environment-based fluid films.
• Subsequently, route the 4.0-metre triaxial cable inside a dedicated metal tray or flexible armor conduit, keeping the assembly isolated from heavy AC motor lines to avoid EMI noise.
• Finally, verify that the cable routing layout adheres to a minimum static bend radius of 25.4 mm (1.0 inch) to preserve internal capacitance values.
