Overview
Configured for non-contact shaft displacement and vibration measurement, the EPRO PR6453/240-101 (PR6453 eddy current probe) provides direct physical sensing of conductive rotating targets. The probe converts target distance into an electrical measurement for machinery monitoring systems. The supplied data specifies a 12.5 mm probe tip, 8 V/mm sensitivity, and a frequency response from 0 to 20 kHz.

Eddy Current Measurement Characteristics
The PR6453/240-101 operates through electromagnetic interaction between the probe and a conductive target. The sensing element maintains a non-contact relationship with the shaft surface, so mechanical contact does not determine the measurement.
The specified sensitivity is 8 V/mm, equivalent to 203.2 mV/mil. The stated +/- 1.5% sensitivity tolerance defines the supplied sensitivity specification.
The 0 to 20 kHz frequency response supports measurement of dynamic shaft motion within the specified bandwidth. The actual measurement configuration depends on the associated signal conditioning and machinery monitoring hardware.
The supplied data identifies the probe for radial shaft vibration, axial position, and rotational speed measurements. Installation must therefore maintain the specified probe-to-target geometry for the intended measurement function.
Frequently Asked Questions
Q: Does the PR6453/240-101 require physical contact with the rotating shaft?
A: No. The probe uses non-contact eddy current sensing and measures the distance to a conductive target.
Q: What sensitivity does the probe provide?
A: The supplied specification states 8 V/mm (203.2 mV/mil) with a tolerance of +/- 1.5%.
Q: What frequency range does the probe support?
A: The specified frequency response is 0 to 20 kHz. The complete measurement bandwidth also depends on the associated signal conditioning equipment.
Field Installation Guidelines
- Mount the probe so its sensing axis remains aligned with the intended conductive target surface.
- Maintain the required probe-to-target gap specified by the applicable system installation documentation.
- Secure the probe mechanically to prevent movement caused by machine vibration.
- Route probe wiring separately from high-current power conductors where practical to reduce electrical interference.
- Apply cable shielding and grounding according to the associated monitoring system and installation documentation.
- Verify the probe body and thread configuration before installation because the supplied data does not identify the exact thread variant for PR6453/240-101.
- Confirm the installed probe position before commissioning radial vibration, axial position, or speed measurements.
- Do not infer electrical power requirements from the probe sensitivity; verify power and signal-conditioning requirements from the applicable system documentation.
