Product Overview
Description
The Bently Nevada 330730-040-01-00 3300 XL 11 mm Extension Cable is a critical, high-performance signal transmission component engineered specifically for integration with the advanced 3300 XL 11 mm proximity transducer system. Designed to facilitate precise machinery protection and condition monitoring on large-scale rotating equipment such as steam turbines, hydro turbines, and heavy-duty compressors, this cable serves as the reliable link between the sensitive eddy current probe and the sophisticated Proximitor signal conditioner. With a specified total system cable length of 5.0 meters (16.4 feet)—including a dedicated 4.0-meter (13.1-foot) armored extension segment—it provides the necessary reach for complex installations where sensors are located at significant distances from monitoring cabinets. The inclusion of a robust armored cable construction offers superior protection against mechanical abrasion, crushing forces, and environmental hazards encountered in demanding power generation and industrial plant settings.
Electrical performance is paramount for accurate vibration and position measurement, and this 3300 XL 11 mm extension cable is meticulously engineered to preserve signal integrity. It features a precise extension cable capacitance of 69.9 pF/m (typical), a parameter critically matched to the electrical characteristics of the 11 mm proximity probe to maintain system linearity and calibration accuracy over its entire length. The cable ensures a stable 50 Ω output resistance and exhibits minimal supply sensitivity (<2 mV/V), guaranteeing that the signal transmitted to the Proximitor is a faithful representation of the dynamic gap measurement, immune to noise from power supply fluctuations. This electrical stability is maintained across an exceptionally wide operating and storage temperature range of -55°C to +170°C, making it suitable for routing through high-temperature areas near turbine casings or in cold outdoor environments.
Key Functions
Applications
This 4.0-meter armored extension cable is essential for applications on large steam and gas turbines, where 11 mm proximity probes monitoring critical thrust bearing position and rotor vibration are often installed far from the control room or monitoring rack. The cable’s precisely controlled capacitance (69.9 pF/m) and stable 50 Ω impedance ensure that the low-level eddy current signals experience minimal attenuation and phase shift over the 5.0-meter total system length, preserving the accuracy of displacement measurements vital for protecting multi-million dollar turbine assets.
Engineered to withstand an operating temperature up to +170°C, this cable is specifically designed for routing through hot zones within power plant enclosures. It can be safely installed near steam lines, hot bearing housings, or within turbine pedestals where ambient temperatures would degrade standard industrial cables. This capability ensures continuous, reliable signal transmission from proximity probes in the harshest thermal environments, preventing data loss and maintaining the integrity of the machinery protection system.
The armored cable construction provides necessary mechanical protection in heavy industrial environments such as hydroelectric facilities, steel mills, and offshore platforms. It resists damage from impact, vibration, crushing, and exposure to oils or chemicals. This durability, combined with its support for standard field wiring (0.2 to 1.5 mm²), makes the 330730-040-01-00 the ideal choice for creating robust, long-life connections between field sensors and 3300/3500 Monitoring System racks in applications where cable survivability is as critical as signal performance.

Compatibility & Ordering Notes
Competitive Advantage
1.Extreme Temperature Endurance Capability
The 3300 XL 11 mm Proximitor Sensor is engineered to operate reliably across an extended temperature range from -52°C to +177°C. This exceptional thermal tolerance allows stable performance in environments such as turbine casings, high-heat industrial zones, and low-temperature outdoor facilities, where standard proximity sensors often experience performance degradation.
2.Installation Versatility for Complex System Layouts
Offering 5.0 m and 9.0 m total system length options and DIN-rail mounting, the 330780-91-00 3300 XL 11 mm Proximitor Sensor adapts easily to diverse installation requirements. This versatility supports both compact cabinet designs and distributed monitoring systems, reducing engineering constraints during system integration.
3.Space-Efficient and Lightweight Construction
With a compact footprint of 8.7 × 3.5 × 7 cm, a 140 mm case length, and a weight of only 0.22 kg, the 3300 XL 11 mm Proximitor Sensor enables high-density installations without adding unnecessary load. Its streamlined design provides a clear advantage in crowded control panels and limited mounting spaces.
