Product Overview
The EPRO CON021 is a panel-mount signal converter for PR642x eddy current sensors. It forms part of a non-contact measuring chain used to monitor shaft vibration, axial displacement, shaft position, eccentricity and speed in rotating machinery. The converter supplies the sensor excitation and converts the probe signal into a voltage output proportional to the measurement distance.

FAQ
What is the main function of CON021?
It excites the eddy current probe, conditions the sensor signal and provides a voltage output proportional to the measured distance.
Which probes are compatible?
The converter is designed for PR6422, PR6423, PR6424, PR6425 and PR6426 sensor families.
Can it handle extended measuring ranges?
Extended ranges use dedicated CON021/91x-xxx configurations. PR6425 applications require an extended-range converter configuration.
Installation Guide
- Confirm the sensor family and required measuring range.
- Mount the converter using the designated fixing points.
- Connect the sensor cable to the LEMO socket.
- Wire the DC supply and output terminals according to the connection diagram.
- Adjust the probe distance while measuring the converter output voltage.
- Verify the complete measuring chain before connecting it to the monitoring system.
Selection Tips
Check the PR642x sensor model, standard or extended measurement range, output configuration and calibration before ordering. For a replacement, compare the full converter designation and sensor compatibility with the existing installation.
