Quick Detail

Description

The 330730-040-02-00 3300 XL 11 mm Extension Cable is a high-integrity signal transmission component specifically engineered for the Bently Nevada 3300 XL 11 mm proximity transducer system. As a specialized 3300 XL 11 mm Extension Cable, the 330730-040-02-00 model acts as the critical bridge between the 11 mm proximity probe and the Proximitor sensor, ensuring that eddy current signals are conveyed with near-zero attenuation. This 3300 XL 11 mm Extension Cable features a 4.0-meter (13.1 feet) cable length, which, when combined with a 1.0-meter probe, creates a calibrated 5.0-meter total system length. Such precision is vital for the 3300 XL 11 mm Extension Cable to maintain the correct scale factor required for monitoring large-scale industrial machinery.

Designed to handle the massive axial displacement and radial vibration of utility-scale turbines, the 330730-040-02-00 3300 XL 11 mm Extension Cable provides a wider linear range than standard 8 mm systems. This 3300 XL 11 mm Extension Cable utilizes a low-capacitance design (65.5 pF/m typical) to ensure frequency response stability across its entire length. To protect the sensitive coaxial junctions, this 3300 XL 11 mm Extension Cable comes equipped with a factory-installed connector protector, which shields the gold-plated brass ClickLoc connectors from environmental contaminants, moisture, and mechanical loosening caused by high-frequency machine oscillations.

Thermal resilience is a core attribute of the 330730-040-02-00. This 3300 XL 11 mm Extension Cable is rated for extreme temperatures ranging from -53°C to +165°C, allowing it to be routed through steam turbine enclosures where standard cables would quickly degrade. Furthermore, the 330730-040-02-00 3300 XL 11 mm Extension Cable is a key part of the upgrade path for aging 7200-series systems. By integrating this 3300 XL 11 mm Extension Cable, operators can leverage the enhanced linearity and temperature stability of modern 3300 XL technology. Whether used in power generation or heavy manufacturing, the 330730-040-02-00 ensures the consistent delivery of high-fidelity data to Bently Nevada 3500 monitoring racks, securing the operational health of critical rotating assets.

Applications

The 330730-040-02-00 is primarily utilized in the power generation sector to monitor large-scale steam and gas turbines. Given its 11 mm system compatibility, this extension cable is essential for capturing large-scale axial thrust measurements where the rotor expansion may exceed the range of standard sensors. It bridges the gap from the probe mounted inside the high-heat turbine casing to the Proximitor sensor located in a safer, cooler junction box, ensuring that 4.0 meters of signal path remains stable even when exposed to ambient steam and high-voltage electromagnetic interference.

In the oil and gas industry, this cable is a critical component for monitoring massive centrifugal compressors and high-speed expanders. The 330730-040-02-00 ensures that radial vibration data from large-diameter shafts is transmitted without phase shifts or signal loss. Because it includes a connector protector, it is ideally suited for offshore platforms or refineries where the cable must endure constant exposure to saltwater mist, synthetic lubricants, and mechanical vibration, maintaining a reliable link for the machinery protection system.

This extension cable is also used for Keyphasor* and speed measurement applications on heavy industrial gearboxes and generators. By maintaining a precise 45 Ω output resistance and low capacitance, the 330730-040-02-00 guarantees that sharp timing pulses are delivered to the monitoring system for accurate phase analysis. Its ability to interface with field wiring from 0.2 to 1.4 mm² makes it a versatile choice for retrofit projects where existing infrastructure must be integrated with new 3300 XL 11 mm transducer technology.

Specifications

Competitive Advantage

1. Superior Thermal Stability in Extreme Environments

The 330730-040-02-00 is engineered to withstand a staggering temperature range from -53°C to +165°C. This outperforms many generic industrial cables that fail under the intense heat of turbine enclosures. By maintaining stable electrical properties at these extremes, the cable prevents "signal drift"—a common issue where temperature changes are misinterpreted by the monitoring system as false vibration or displacement, thereby reducing the risk of costly false trips.

2. Enhanced Signal Integrity with Connector Protection

A significant competitive edge is the inclusion of the connector protector and gold-plated ClickLoc connectors. This design ensures a gas-tight, vibration-proof connection that is shielded from moisture and oil wicking. By preventing connector corrosion and accidental loosening, the 330730-040-02-00 significantly increases the Mean Time Between Failures (MTBF) compared to unprotected cables, ensuring that the safety-critical machinery protection loop remains closed and reliable.

3. Precision Impedance and Capacitance Matching

Unlike third-party "compatible" cables, the 330730-040-02-00 is factory-calibrated with a typical capacitance of 65.5 pF/m. This precise matching ensures that the entire 5.0-meter system length remains within the strict API 670 linearity specifications. This level of accuracy is vital for large 11 mm systems, where even minor variations in cable impedance can lead to significant errors in measuring critical axial thrust positions on multi-million dollar turbine rotors.
