Description

Bently Nevada 330130-080-00-00 3300 XL Standard Extension Cable

The Bently Nevada 330130-080-00-00 is a high-precision coaxial extension cable designed for the 3300 XL 8 mm Proximity Transducer System. This cable serves as the vital signal link between a proximity probe and a Proximitor sensor, enabling the non-contact measurement of static and dynamic shaft motion. It is specifically engineered to maintain the electrical characteristics required for accurate vibration monitoring and axial position sensing in critical rotating machinery.

Signal Integrity and Material Engineering

To ensure reliable data transmission in electromagnetically noisy environments, the 330130-080-00-00 utilizes advanced coaxial shielding. Specifically, the cable is insulated with a high-performance fluoro-polymer jacket, providing exceptional resistance to moisture, chemical corrosion, and mechanical wear. Furthermore, the gold-plated brass connectors utilize the ClickLoc locking system, which provides a secure mechanical connection and low electrical resistance. As a result, the transducer system achieves a consistent linear scale factor of 7.87 V/mm (200 mV/mil), which is essential for preventing false machinery trips and ensuring asset safety.

Technical Specification Matrix

Industrial Application and System Integration

The 330130-080-00-00 is a standard component in Turbine Supervisory Instrumentation (TSI) used across power generation and oil and gas sectors. Moreover, the 8.0-meter length is typically matched with a 1.0-meter probe to create a 9.0-meter total electrical system length. In addition, the cable’s wide operating temperature range allows for installation in close proximity to hot turbine housings and compressor casings. Therefore, this extension cable provides a durable and standardized solution for connecting remote monitoring racks to sensors embedded deep within industrial machinery.

FAQ

What does the “00” option represent in this part number?

The “00” suffix indicates that this cable is supplied without a connector protector and without stainless steel armor. Specifically, it is intended for installation in clean conduits or protected cable trays where mechanical impact or fluid ingress at the connector junction is not a primary concern.

Is it necessary to match the cable length to the Proximitor sensor?

Yes, Bently Nevada proximity systems are calibrated for specific total electrical lengths, usually 5.0 or 9.0 meters. Furthermore, using an 8.0-meter extension cable with an incorrect probe or sensor will cause a calibration error. Consequently, always verify the “Total Length” parameter marked on your 3300 XL Proximitor sensor before installation.

Can this cable be used in high-temperature environments?

This cable is rated for continuous operation up to +177 °C (+351 °F). As a result, it is ideal for routing near steam lines or within gas turbine enclosures where standard PVC-insulated cables would fail. Ultimately, the high-grade FEP insulation ensures the electrical properties remain stable even at these thermal extremes.

How does the ClickLoc connector prevent signal loss?

The ClickLoc design features a mechanical detent that ensures the coaxial connectors are fully engaged. Accordingly, this prevents the connectors from vibrating loose over time, a common issue that causes signal “noise” or intermittent connectivity in industrial vibration monitoring loops.
