Description

Bently Nevada 330130-040-03-00 | 3300 XL 8 mm Armored Extension Cable

The Bently Nevada 330130-040-03-00 is a high-durability armored extension cable designed for the 3300 XL 8 mm Proximity Transducer System. This component acts as the vital electrical bridge between the proximity probe and the Proximitor sensor. By utilizing specialized coaxial shielding, the cable maintains signal integrity while transmitting high-frequency eddy current data. Its armored exterior specifically protects the delicate internal conductor from mechanical crushing, abrasion, and sharp bends, which are common in heavy-duty industrial environments.

Signal Integrity and Environmental Protection

Reliable machinery protection requires consistent electrical properties. The 330130 series is engineered to provide a constant impedance, ensuring that the transducer system remains within its 0.8% linearity specification. The stainless steel armor prevents physical damage in high-traffic areas or tight machine conduits. Furthermore, the cable features high-performance insulation that resists degradation when exposed to synthetic lubricants, moisture, and extreme temperature cycling. This makes it an ideal choice for monitoring radial vibration and axial position in steam turbines, generators, and large scale motors.

Technical Specifications

The 330130-040-03-00 configuration includes the following technical characteristics:

Advanced Connectivity and Installation

Equipped with gold-plated ClickLoc connectors, this extension cable ensures low-resistance electrical contact and resists oxidation over long-term deployments. The inclusion of connector protectors (Option 03) prevents the coaxial ends from being damaged or disconnected due to vibration. Because the system’s total electrical length is critical for calibration, this 4.0-meter cable must be matched with a 1.0-meter probe to achieve a total system length of 5.0 meters. This precise matching ensures the scale factor remains accurate at 7.87 V/mm (200 mV/mil).

Strategic Machinery Protection

Utilizing the 330130-040-03-00 armored cable within a Turbine Supervisory Instrumentation (TSI) framework enhances overall plant safety. The ruggedized design minimizes signal noise caused by electromagnetic interference (EMI), providing cleaner data for vibration analysis. By protecting the signal path from the harsh interior of the machine to the external monitoring rack, this cable helps maintenance teams detect rotor instability and bearing wear before they lead to costly equipment downtime or catastrophic failure.
