Overview：
EPRO PR6423/003-030 Eddy Current Sensor
The EPRO PR6423/003-030 is a high-precision, non-contact eddy current sensor developed by EPRO (now part of Emerson AMS). This sensor measures radial and axial dynamic displacement, static position, shaft eccentricity, and rotational speed of shafts.
Technical principle: The coil at the probe tip of the PR6423/003-030 carries a high-frequency current, generating an alternating magnetic field. When the probe approaches a metallic target, such as a rotating shaft, eddy currents are induced on the target surface. The magnetic field generated by the eddy currents alters the impedance of the probe coil. Impedance variation has a unique linear relationship with the gap between the probe and the target. A compatible signal conditioner, such as CON011 or CON021, converts this impedance variation into a standard electrical output signal.

Function & Features：
- High Precision and Pre-Calibration: The PR6423/003-030 has low linear error (e.g., <0.25% or ±1.5%) and is factory-calibrated for specific materials, such as 42CrMo4.
- Full-Dimension Measurement Capability: The PR6423/003-030 supports wide frequency response with DC response (0 Hz–10 kHz), capable of simultaneously capturing dynamic vibration (AC component) and static position/shaft axial displacement (DC component).
- Systematic Application: The PR6423/003-030 is usually used together with the CON021 signal conditioner/converter, converting the signal into standard voltage or current output, making it convenient to connect to monitoring systems such as MMS3000 or MMS6000.
Questions & Answers
💡 FAQ
Q: Are there any special requirements for installing the PR6423/003-030?
A: The following points require attention:
Gap Adjustment: The probe must be installed within the linear measurement range. The initial gap for this model is typically 0.5 mm (20 mils), with a linear range of 2 mm (80 mils).
Shaft Diameter Requirement: The minimum diameter of the measured shaft must be 25 mm (0.79 in); otherwise, measurement accuracy may be affected.
