Product Overview

The Epro PR6423/10R-131+CON031 combines an 8 mm eddy current sensor with a CON031 eddy current signal converter for non-contact measurement of rotating machinery movement. The sensor monitors the relative position between the probe and a conductive shaft or target, while the converter prepares the sensor signal for downstream monitoring equipment.

This combined configuration can be used where shaft displacement, axial position, radial movement, or vibration-related motion needs to be measured without physical contact with the rotating component. The sensing element is installed near the monitored target, while the signal converter forms the interface between the sensor output and the associated monitoring system.

Typical installations can include turbines, compressors, generators, motors, pumps, and other rotating machinery. The combined sensor-and-converter arrangement is particularly useful when a defined measurement channel is required for an existing Epro monitoring architecture.

Measurement quality depends on the complete installation rather than the sensor alone. Probe alignment, target condition, probe-to-target relationship, mechanical mounting, cable connections, converter operation, and compatibility with the receiving monitoring equipment should all be checked during commissioning and maintenance.

Working Principle

The PR6423/10R-131 sensor uses an eddy current sensing principle to detect changes in the distance between the probe and a conductive target. Relative movement of the shaft or rotor changes the electromagnetic response at the sensing point.

The sensor response is transferred to the CON031 signal converter, which conditions the signal for the associated monitoring equipment. The downstream system can use this conditioned measurement to evaluate shaft position, displacement, or vibration-related movement.

Conductive Shaft / Target → PR6423/10R-131 Sensor → CON031 Signal Converter → Monitoring Input → Machinery Monitoring System → Alarm / Protection

The sensor and converter operate as connected stages of the same measurement channel. An abnormal output can therefore originate from the mechanical target relationship, sensor installation, wiring, converter, or receiving monitoring input rather than from the sensing element alone.

Role in an Epro Eddy Current Monitoring Architecture

The PR6423/10R-131+CON031 forms the field sensing and signal-conditioning section of an Epro eddy current monitoring architecture. The PR6423 sensor establishes the non-contact measurement point, while the CON031 converts the sensor response into a form suitable for compatible downstream equipment.

Rotating Shaft → PR6423/10R-131 → CON031 → Monitoring Input → Machinery Monitoring System → Alarm / Protection

The combined model should be evaluated as part of the complete measurement channel, with particular attention to the interface between the CON031 output and the receiving monitoring equipment.

Industrial Applications

Installation and Maintenance

1. Verify the complete PR6423/10R-131+CON031 part number before installation or replacement.
2. Confirm compatibility between the PR6423/10R-131 sensor, CON031 converter, existing cabling, and receiving monitoring equipment.
3. Isolate the rotating machinery and follow the applicable site safety procedure before working on the sensing installation.
4. Inspect the sensor tip, sensor body, converter, and accessible connections for contamination or physical damage.
5. Verify that the probe mounting arrangement permits correct positioning relative to the conductive shaft or target.
6. Establish the required probe-to-target relationship according to the applicable Epro measurement-system requirements.
7. Check probe alignment and confirm that the mounting structure remains mechanically secure during operation.
8. Route sensor and converter wiring to minimize mechanical stress, excessive bending, heat exposure, and avoidable electrical interference.
9. Verify the connection between the PR6423 sensor and CON031 converter and check all accessible terminations.
10. Check the conditioned output signal after installation and compare it with expected machine operating behavior.
11. If abnormal readings occur, inspect probe position, target condition, cabling, converter operation, and monitoring input before replacing the sensor.
12. After replacement, perform a complete measurement-channel and monitoring-system functional test before returning the machinery to normal operation.

Technical FAQs

What does the combined PR6423/10R-131+CON031 configuration contain?

It combines the PR6423/10R-131 8 mm eddy current sensor with a CON031 eddy current signal converter, forming a defined sensing and signal-conditioning channel for compatible monitoring equipment.

How does the monitored target influence the measurement?

The sensor responds to changes in its electromagnetic relationship with the conductive target. Target material, surface condition, probe alignment, and the probe-to-target relationship can therefore affect the resulting measurement signal.

What should be checked if the CON031 output does not match the expected machine condition?

Check the sensor installation and target relationship first, followed by sensor-to-converter wiring, converter operation, and the receiving monitoring input. The complete measurement path should be evaluated before identifying a specific component as defective.

Is the PR6423/10R-131+CON031 suitable as a replacement for another PR6423 combination?

Replacement should be based on the complete part-number configuration and system compatibility rather than the 8 mm probe diameter alone. The sensor configuration, CON031 interface, cable arrangement, and downstream monitoring input should all be verified before substitution.
