Product Overview
The EPRO CON031 is an eddy current signal converter designed for use with PR642x series probes in rotating machinery monitoring systems. It converts probe signals into voltage outputs proportional to the distance between the probe tip and the conductive measurement target. Typical applications include shaft vibration, axial displacement, shaft position, eccentricity and speed measurement.

- Provides a voltage output proportional to probe-to-target distance.
- Uses screw terminals for direct sensor wiring without a LEMO connector.
- Suitable for integration into machinery monitoring and protection systems.
FAQ
Which probes are compatible with CON031?
It is designed for the EPRO PR6422, PR6423, PR6424, PR6425 and PR6426 sensor families. The converter must be correctly matched and calibrated to the probe.
What is the nominal supply voltage?
The nominal supply voltage is -24 VDC.
How is the probe connected?
The CON031 uses screw terminals for the sensor connection rather than the LEMO socket used on the CON021.
Installation Guide
- Verify the converter model and its calibration compatibility with the PR642x probe.
- Mount the converter securely in the designated enclosure or mounting location.
- Connect the probe wires to the designated sensor terminals.
- Connect the -24 VDC supply and output signal wiring with correct polarity.
- Adjust the probe-to-target distance while monitoring the converter output voltage.
- Verify the signal response and grounding before commissioning.
Selection Tips
Check the probe model, measurement range, calibration data and wiring configuration before selecting CON031. For extended measurement ranges, select the matching CON031/91x-xxx configuration rather than a standard-range converter. Confirm the converter's terminal arrangement and calibration against the installed measuring chain.
