Quick Detail

Description

The Bently Nevada 330854-080-24-00 is a specialized 3300 XL 25 mm Extension Cable, engineered as a critical link for high-precision, long-range displacement measurement systems in heavy industrial machinery. This premium extension cable is specifically designed to interface with 3300 XL 25 mm Proximitor Sensors and their corresponding large-diameter probes, forming a complete transducer loop optimized for monitoring substantial mechanical movements such as differential expansion in large turbines. A defining feature of this model is its High Temperature FluidLoc cable construction, which provides an impermeable barrier against the ingress of oils, coolants, and other industrial fluids—a common cause of failure in standard cables—while simultaneously offering enhanced thermal resilience for demanding environments.

This 3300 XL 25 mm extension cable boasts a substantial 8.0-meter (26.2-foot) length, providing the necessary reach to connect sensors mounted on massive machinery to remotely located monitoring systems or junction boxes. The cable assembly is terminated with connectors that interface with a sensor body featuring a 46 mm overall case length and a 0 mm unthreaded length, ensuring a compact and secure mechanical interface. The complete assembly, with a total system dimension of 8.1x5.58x10.20cm and a weight of 0.24kg, is designed for robust yet manageable installation in industrial settings. Configured without specific agency approvals, this extension cable is tailored for applications where intrinsic safety certification is not a primary requirement, focusing instead on unparalleled performance and durability.

Applications

This extension cable is essential for completing the measurement loop in differential expansion (DE) monitoring systems on large steam turbines. Its 8.0-meter High Temperature FluidLoc cable reliably transmits signals from the 25 mm probe, mounted to measure the gap between the turbine rotor and casing, back to the 3300 XL proximitor sensor, enabling accurate tracking of substantial thermal growth during startup and load changes to prevent catastrophic internal rubbing.

The cable is applied in heavy industrial environments such as power generation plants and large compressor stations, where machinery is prone to fluid leaks from seals and lubrication systems. The FluidLoc cable protection ensures reliable, long-term operation by preventing oil and coolant ingress, which could otherwise degrade signal quality or cause premature cable failure in these wet or oily locations.

It is used in applications requiring signal transmission over moderate distances in high-vibration areas. The cable's robust construction and specified shock survivability make it suitable for routing signals from sensors on large, vibrating foundations—like those of gas turbines or large pumps—to control panels or monitoring racks located a safe distance away, ensuring data integrity is maintained despite challenging physical conditions.

Specifications

Competitive Advantage

1.High Temperature FluidLoc Cable for Unmatched Environmental Protection

The integration of High Temperature FluidLoc cable technology provides a decisive advantage in hostile industrial environments. This specialized construction creates a hermetic seal against oil, coolant, and process fluid ingress, a common failure mode for standard cables. Simultaneously, it is engineered to withstand elevated temperatures, ensuring long-term reliability and signal integrity in the oily, high-heat zones typical of turbine halls and compressor stations, drastically reducing maintenance interventions and downtime.

2.Optimized Length and Interface for Large-Displacement Systems

With an 8.0-meter length and connectors designed for the 3300 XL 25 mm sensor platform (46 mm case, 0 mm unthreaded length), this cable is precisely engineered for large-displacement monitoring applications. It provides the necessary reach and a secure, low-resistance interface specifically tailored to maintain the electrical characteristics required for accurate transmission of signals from 25 mm probes, which have a sensitivity of 0.787 V/mm and a massive linear range, ensuring no signal degradation in critical differential expansion measurement loops.

3.Robust Construction for Demanding Physical Environments

Built to survive in the challenging conditions of heavy industry, this extension cable offers exceptional mechanical ruggedness. Its design contributes to high shock survivability, protecting the internal conductors and connections from the constant vibration and occasional impacts found near large rotating equipment. This durability, combined with a wide operating temperature range (-58°C to +108°C), ensures dependable performance and a long service life, providing a more reliable and cost-effective solution compared to less robust standard extension cables.
