Bently Nevada 330130-075-01-00 Extension Cable

330130-075-01-00 Bently Nevada Armored Extension Cable

Product Introduction

The Bently Nevada 330130-075-01-00 extension cable serves as a robust interconnect component within the 3300 XL 8 mm proximity transducer system. This cable connects the 8 mm probe to the Proximitor Sensor, ensuring precise shaft vibration, thrust position, and eccentricity measurements in critical rotating machinery.

Manufactured in the U.S.A., this 3300 XL extension cable offers a 7.5-meter (24.6 feet) length with a rugged armored outer jacket. The armor provides superior mechanical protection against crushing, abrasion, and physical stress in harsh turbine and compressor environments. Additionally, the 330130-075-01-00 incorporates gold-plated ClickLoc connectors that deliver exceptional corrosion resistance and secure, reliable mating.

This model carries no specific country approvals (00 suffix), offering maximum flexibility for global installations without regional compliance constraints. Its electrical characteristics, including 1.65Ω center conductor resistance and 69.9 pF/m capacitance, guarantee accurate, low-noise signals over the full 7.5-meter length.

System Compatibility & Performance

This 3300 XL extension cable operates exclusively with 3300 XL 8 mm probes and Proximitor Sensors. The complete system delivers a linear range of 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils). This range corresponds to an output voltage of approximately –1 to –17 Vdc.

Performance specifications are validated using an AISI 4140 steel target, a -24 Vdc power supply, and a 10 kΩ load. For applications involving different target materials, note that system accuracy and interchangeability specifications may not apply. The 330130-075-01-00 incorporates patented TipLoc and CableLoc molding methods, which significantly enhance the mechanical bond between the probe tip and body while providing exceptional pull strength. Such robustness proves essential in high-vibration environments like steam turbines, centrifugal compressors, and large generators.

Furthermore, the armored construction eliminates the need for additional conduit in many installations. This simplifies cable routing through tight machine compartments and reduces overall installation costs. The gold-plated ClickLoc connectors ensure reliable, corrosion-free connections even in humid or chemically aggressive environments.

Installation Guidelines

Proper installation of the Bently Nevada 330130-075-01-00 requires careful attention to total system length. Specifically, the extension cable length and the probe length must sum exactly to the Proximitor Sensor's total specified length. Any deviation can introduce measurement inaccuracies.

For field wiring between the Proximitor Sensor and the monitor, use 0.2 to 1.5 mm² (16 to 24 AWG) tinned, 3-conductor shielded triad cable. The maximum allowable field wiring distance is 305 meters (1,000 feet). However, longer runs may cause signal rolloff at high frequencies, so always consult the frequency response graphs provided in the product documentation.

Although each cable includes silicone tape as an alternative to connector protectors, we strongly advise against using this tape in applications where the probe-to-extension cable connection contacts turbine oil. For oil-wetted environments, consider the FluidLoc option available on other 3300 XL extension cable models.

Frequently Asked Questions (FAQ)

Q1: What protection does the armored jacket provide?
A1: The armored jacket delivers superior mechanical protection against crushing, abrasion, and physical impact. This makes the 330130-075-01-00 ideal for harsh turbine and compressor environments where standard cables would suffer damage.

Q2: Can I use the 330130-075-01-00 with non-3300 XL series probes?
A2: No. This cable is specifically engineered for 3300 XL 8 mm probes and Proximitor Sensors. Using it with other series may result in incompatible electrical characteristics and mechanical fitment issues.

Q3: What does the "00" approval suffix mean for this model?
A3: The 00 suffix indicates no specific country approvals are required. This offers maximum flexibility for global installations without regional regulatory constraints, making it ideal for international projects.

Q4: How do I calculate the correct total cable length for my system?
A4: Add the probe length to the extension cable length. The sum must equal the total length specified for your Proximitor Sensor. For the 330130-075-01-00, the 7.5-meter extension is typically paired with a probe whose length complements the sensor's total requirement.

Q5: Are the ClickLoc connectors compatible with standard probe connectors?
A5: Yes. The gold-plated ClickLoc connectors on the 330130-075-01-00 are fully compatible with all 3300 XL probe and Proximitor Sensor connectors. Their corrosion-resistant design ensures reliable signal integrity even in challenging industrial environments.
