Quick Detail

Description

The 330130-070-03-00 is a high-performance 3300 XL Standard Extension Cable designed by Bently Nevada to serve as a critical bridge within the industry-leading 3300 XL 8 mm proximity transducer system. Specifically engineered to maintain the integrity of high-frequency displacement signals, this 3300 XL Standard Extension Cable connects proximity probes to Proximitor sensors, enabling precise monitoring of radial vibration, axial position, and Keyphasor signals on critical rotating machinery. With its 7.0-meter (22.9 feet) length, the 330130-070-03-00 provides the necessary reach for complex machinery layouts while ensuring that the low-level voltage signals generated by the probe are transmitted without degradation to the monitoring suite.

A defining characteristic of this 3300 XL Standard Extension Cable is its specialized 75Ω triaxial construction. Unlike standard coaxial cables, the triaxial design of the 330130-070-03-00 incorporates an additional layer of shielding, which is essential for protecting sensitive vibration data from electromagnetic interference (EMI) and radio frequency interference (RFI) typically found in power plants and industrial processing facilities. This model is further enhanced with the armored cable option and a factory-installed connector protector. The armor provides a rugged physical barrier against mechanical crushing, abrasion, and harsh chemical exposure, while the connector protector ensures a moisture-proof, vibration-resistant seal at the critical probe-to-cable junction.

Applications

The 330130-070-03-00 3300 XL Standard Extension Cable is widely deployed in the power generation and oil and gas sectors to monitor critical fluid-film bearing machinery such as steam turbines, gas compressors, and large generators. Its 7.0-meter length combined with the armored protection makes it ideal for routing through turbine decks and internal machine housings where cables are frequently exposed to mechanical stress, oil wicking, and heavy foot traffic. It provides the clean, shielded signal path necessary for real-time vibration analysis, preventing catastrophic failures through accurate data transmission.

In petrochemical refineries and chemical processing plants, this 3300 XL Standard Extension Cable is the preferred choice for hazardous area monitoring loops. The armored design and 75Ω triaxial shielding ensure that measurement signals from remote pumps and motors are transmitted back to the control room or DCS without interference from nearby heavy-duty electrical equipment. The integrated connector protector is particularly beneficial in these environments, as it prevents moisture and corrosive chemicals from compromising the electrical connection, ensuring 24/7 reliability in outdoor or wash-down areas.

This cable is also indispensable for high-speed speed sensing and phase reference (Keyphasor) applications across various manufacturing industries. When used with a 3300 XL proximity probe, the 330130-070-03-00 facilitates the precise tracking of shaft rotational speed and timing pulses. Its low typical capacitance (69.9 pF/m) ensures that high-speed pulses remain sharp and clear, which is essential for advanced diagnostic techniques like orbit analysis and waterfall plots. This precision is vital for balancing operations and capturing transient data during critical machine startup and shutdown phases.

Specifications

Competitive Advantage

1. Robust Armored Protection and Connector Security

The 330130-070-03-00 offers superior mechanical resilience through its armored cable design, which protects the inner conductors from crushing, kinking, and environmental degradation. Unlike unarmored alternatives, this cable can withstand the rigors of heavy industrial environments without the need for additional conduit in many cases. The inclusion of the connector protector further enhances reliability by shielding the most vulnerable part of the sensor loop from fluid ingress and accidental disconnection caused by high-frequency vibration.

2. Full API 670 Compliance and Interchangeability

A major competitive edge of the 3300 XL Standard Extension Cable is its strict adherence to the API 670 standard. This ensures that the 330130-070-03-00 is 100% interchangeable with other Bently Nevada 3300 XL components regardless of the manufacturing date. For the user, this means no field calibration is required when replacing a cable, which drastically reduces maintenance labor, simplifies spare parts inventory, and ensures the machinery protection system returns to service as quickly as possible.

3. Advanced Triaxial Shielding for Signal Purity

The 75Ω triaxial construction of the 330130-070-03-00 provides an extra layer of electrical isolation compared to standard coaxial cables. This design is specifically optimized to block electromagnetic noise from large motors and variable frequency drives (VFDs). By maintaining a consistent typical capacitance and high insulation resistance, this cable ensures that the vibration data reaching the monitoring system is a true reflection of the machine's health, eliminating false alarms and providing the accuracy needed for expert-level fault diagnosis.
