Product Overview
The EPRO PR6423/019-040+CON021 is an eddy current measuring chain combining a PR6423 non-contact displacement probe with a CON021 signal converter. The PR6423 sensor has an 8 mm probe-head diameter and is designed for shaft vibration and displacement monitoring. The converter conditions the probe signal and provides a voltage output for integration with industrial machinery monitoring systems.

FAQ
Does 8 mm refer to the measuring range?
No. The 8 mm specification refers to the PR6423 probe-head diameter. Its standard nominal static measuring range is ±1.0 mm.
What is included in this measuring chain?
The designation identifies the PR6423/019-040 sensor and CON021 signal converter combination.
What does the converter do?
The CON021 provides sensor excitation, signal conditioning and a proportional voltage output.
Installation Guide
- Verify that the probe and converter are the matched measuring-chain components.
- Install the PR6423 probe using the correct M10 × 1 mounting arrangement.
- Protect the armored sensor cable from twisting, crushing and contact with moving machine parts.
- Connect the probe to the CON021 LEMO input.
- Connect the converter supply and output wiring.
- Adjust the probe gap using the converter output voltage and verify the measurement signal.
Selection Tips
Confirm the full PR6423 probe designation, cable arrangement, converter type and calibration before purchasing. The probe-head diameter is not the same as the measurement range. For replacement applications, match the existing measuring-chain configuration and monitoring-system input requirements.
