Description

The Bently Nevada 330130-085-02-05 serves as a vital component within the 3300 XL 8 mm Proximity Transducer System. Consequently, industrial facilities deploy this high-performance extension cable to route static and dynamic proximity signals back to the Proximitor Sensor from fluid-film bearing machines.

Hardware Specifications

Transducer Calibration and Gap Voltage Validation

To establish the linear range centerpoint, field technicians must execute precise gap voltage validation during mechanical commissioning. Specifically, technicians calibrate the sensor to target a nominal -10 VDC gap voltage. Consequently, this voltage tracks the exact physical midpoint of the eddy-current probe scaling matrix. By securing this alignment, the system captures accurate rotor dynamics data and simultaneously maintains high cross-talk suppression when operators deploy multiple proximity probes in close proximity.

Frequently Asked Questions

Q: How does the 8.5-meter cable length affect the configuration of the proximity probe loop?

A: The 3300 XL system strictly enforces total electrical matching length rules. Because this cable measures exactly 8.5 meters, technicians must pair it with a 0.5-meter proximity probe. As a result, this loop satisfies the 9.0-meter system parameter mandatory for specific 9.0-meter Proximitor Sensors.

Q: What structural benefit do the factory-installed connector protectors provide?

A: The “02” designation provides removable connector protectors over the miniature coaxial ClickLoc interfaces. Consequently, these protectors shield the raw gold-plated pins from moisture, dirt, and oil during installation routing before technicians complete the final mating process.

Field Installation Guidelines

• Always verify that the combined length of the probe and extension cable matches the specific matching parameters of the Proximitor Sensor before completing final routing.
• Do not use mechanical tools to tighten the miniature coaxial ClickLoc connectors; instead, rotate the coupling nut by hand until you feel a distinct tactile click.
• Route the unarmored FEP coaxial cable away from sharp casing edges, and maintain the minimum bend radius to prevent structural fatigue or signal degradation.
• Remove the temporary connector protectors immediately before joining the plugs, and then pull the protective insulation sleeves completely over the mated body.
