Product Overview

The Bently Nevada 330130-045-03-00 functions as the vital high-integrity link within the 3300 XL Proximity Transducer System. This 4.5-meter armored extension cable transmits low-voltage eddy current signals from the proximity probe to the Proximitor® sensor with near-zero attenuation. Engineered to survive the rigorous thermal and mechanical stresses of turbine decks, this cable utilizes advanced shielding to eliminate EMI/RFI interference. We supply this unit as 100% New and Original, Made in the U.S.A., ensuring your machinery protection system maintains factory-calibrated accuracy.

Technical Specifications

Engineering Advantages

• Mechanical Fortification: The flexible stainless steel armor prevents cable crushing, shearing, and abrasion in high-traffic industrial areas. This armor significantly extends the service life of the sensor loop compared to non-armored variants.

• Connector Integrity: Option -03 includes integrated connector protectors. These prevent the ClickLoc connectors from loosening due to machinery vibration and seal the connection points against oil, moisture, and debris infiltration.

• Signal Precision: The cable maintains a strict 75-ohm impedance and 3.0 mm diameter. This precision ensures the Proximitor® sensor receives the exact capacitance and inductance profile required to calculate shaft displacement without signal "noise" or "ghosting."

• High-Temperature Resilience: The FEP (Fluorinated Ethylene Propylene) insulation withstands continuous exposure to hot lubrication oils and ambient heat up to 180°C, making it ideal for bearing housing installations.

FAQs

Is the 330130-045-03-00 compatible with the older 3300 (non-XL) system?

While the connectors are physically similar, the 330130 extension cable is electrically optimized for the 3300 XL system. Using an XL cable with a non-XL Proximitor® may cause a slight deviation in the linear scale factor. For API 670 compliance, always match your cable series to your Proximitor® and Probe series.

What is the benefit of the connector protectors?

Connector protectors serve two purposes: they provide a secondary locking mechanism to prevent disconnection under high vibration and provide an environmental seal. If your installation is exposed to splashing oil or steam, the protectors are essential to prevent fluid ingress from shorting the coaxial signal.

How do I ensure a proper connection with ClickLoc connectors?

Ensure you hear or feel the "click" when joining the probe to the extension cable. Do not use pliers or wrenches on the connectors; they are designed for finger-tightening. Once connected, slide the protector over the junction to secure the link.

Can I shorten this cable if 4.5 meters is too long?

No. Bently Nevada proximity systems are tuned to specific electrical lengths (typically 5.0m or 9.0m total system length). Cutting the cable changes the total capacitance and inductance, which will immediately invalidate the sensor's calibration and accuracy. Use a 4.5m cable only when paired with a 0.5m probe to achieve a 5.0m system.
