Eddy-Current Probe Signal Extension and Rotor Monitoring Interface
The 330130-040-12-CN extension cable transfers eddy-current probe signals between the proximity probe and the compatible Proximitor Sensor or monitoring module. Moreover, its 75 ohm triaxial FEP insulated construction maintains signal integrity for shaft displacement measurement circuits.
The cable design supports Bently Nevada proximity measurement systems by preserving probe scaling characteristics and electrical response parameters. In addition, the cable assembly uses FluidLoc protection to reduce the risk of fluid penetration along the cable structure in industrial environments.
For 3300 XL TSI applications, correct cable length matching maintains the specified electrical characteristics of the eddy-current measurement loop. Therefore, installation teams must verify probe, extension cable, and Proximitor Sensor compatibility before system commissioning.
Frequently Asked Questions
Q: What function does the 330130-040-12-CN provide in a 3300 XL monitoring system?
A: The cable extends the connection distance between the proximity probe and the Proximitor Sensor while maintaining the electrical characteristics required for shaft displacement measurement.
Q: Does the 330130-040-12-CN require an external power supply?
A: No. The extension cable is a passive component and does not consume external electrical power.
Q: What cable construction does this model use?
A: The model uses a 75 ohm triaxial cable with fluoroethylene propylene (FEP) insulation and FluidLoc cable protection with connector protectors.
Field Installation Guidelines
- Install the cable according to the specified Bently Nevada 3300 XL system wiring requirements.
- Maintain separation between the extension cable and high-current power conductors to reduce electromagnetic interference.
- Avoid sharp bending, excessive mechanical tension, and physical damage to the FEP insulation layer.
- Verify connector protector installation before placing the system into operation.
- Confirm the complete probe, extension cable, and Proximitor Sensor combination before performing gap voltage checks and signal validation.
