Epro PR6424/010-130 5mm Eddy Current Probe

Product Description

The PR6424/010-130 is a compact eddy current proximity probe from Emerson EPRO designed for high-resolution shaft vibration and displacement measurement in rotating machinery. Its reduced footprint makes it suitable for installations where mounting space is restricted while maintaining accurate non-contact measurement performance.

This probe is typically deployed in turbine systems, compressors, pumps, and gearbox assemblies when integrated with compatible EPRO signal converters such as CON011 or CON021.

FAQ

Q1: Can the PR6424/010-130 operate without a converter?
No. It must be paired with a compatible eddy current signal converter such as CON011 or CON021.

Q2: Is this probe suitable for very small shafts?
Yes. It is designed for shaft diameters down to approximately 15 mm.

Q3: Does cable length affect measurement accuracy?
Yes. Cable length and configuration must match system calibration requirements.
