Product Overview
The EPRO PR6423/00R-010 + CON031 is a complete eddy current measurement set consisting of an EPRO PR6423 series sensor and a CON031 converter. It is designed for non-contact measurement of shaft vibration, displacement and position in critical rotating machinery such as steam turbines, gas turbines, compressors, pumps and fans.
The PR6423 sensor and CON031 converter form a factory-calibrated measurement chain, delivering a stable analog output proportional to the gap between the probe tip and the conductive target surface. The CON031 converter connects to the sensor via screw terminals and is typically used where a bare-end cable connection is preferred over LEMO plug connectors.

FAQ
What is PR6423/00R-010 + CON031?
It is a complete EPRO eddy current measurement set, including a PR6423 series sensor and a CON031 converter, used for non-contact shaft vibration and displacement monitoring.
What does the “/00R-010” suffix mean?
It defines a specific PR6423 configuration, typically related to cable length, thread type and connector style. Exact details should be confirmed against the product label.
Why use CON031 instead of CON021?
CON031 connects to sensors with bare-end cables via screw terminals, while CON021 typically uses LEMO plug connectors. CON031 is often preferred for direct cabinet wiring or retrofit applications.
