Bently Nevada 05701-A-0302 Eddy Current Proximity Probe

Bently Nevada 05701-A-0302 is an eddy current proximity probe for non-contact measurement of shaft vibration and axial position. It converts the clearance between probe tip and rotating metal shaft into linear voltage signal and transmits signal to proximitor and monitoring rack.

This proximity probe is built to withstand high vibration and temperature environments inside rotating machinery. It is compatible with Bently Nevada 3500 series monitoring system. As aftermarket spare parts, it is widely used for maintenance, replacement and retrofit of turbine and compressor vibration monitoring systems.

FAQ

1. Q: Can Bently Nevada 05701-A-0302 probe work alone without proximitor and monitoring rack?
   A: It needs matched proximitor, extension cable and monitoring module, cannot operate as standalone hardware.
2. Q: What are common probe failure symptoms?
   A: Signal loss, voltage drift, damaged probe tip, cable insulation aging and intermittent signal fluctuation.
3. Q: How to complete commissioning and diagnosis?
   A: Inspect cable connection and insulation; adjust probe installation gap, verify gap-voltage linearity and check signal output.
