Product Overview

The Epro PR6423/013-030+CON011 combines an 8 mm PR6423 series eddy current sensor with a CON011 eddy current signal converter for non-contact measurement of conductive machinery targets. The sensor performs the mechanical displacement sensing, while the converter handles the associated signal-conditioning stage.

This combination is intended for rotating equipment where changes in shaft position or mechanical movement need to be detected without physical contact. It can be applied to turbines, compressors, generators, pumps, and other machinery where continuous displacement or vibration-related measurements are part of the monitoring strategy.

Using the sensor together with its signal converter establishes a defined measurement path from the monitored shaft to the machinery monitoring system. The probe is installed at the measurement location, while the CON011 processes the sensor response before the signal is passed to downstream monitoring equipment.

During commissioning and maintenance, the sensor and converter should be evaluated as separate stages of the same measurement channel. Probe position, target condition, sensing gap, cable connections, converter operation, and the receiving monitoring input can each affect the final measurement.

Working Principle

The PR6423/013-030 sensor operates using the eddy current principle. Its sensing field interacts with a nearby conductive target, and changes in the distance between the probe and target produce corresponding changes in the sensor response.

When the probe is positioned near a rotating shaft, radial or axial shaft movement changes the probe-to-target gap. The resulting electrical response is transferred to the CON011 signal converter, which conditions the sensor signal for use by the downstream monitoring system.

Conductive Shaft / Target → PR6423/013-030 Sensor → CON011 Signal Converter → Machinery Monitoring System → Alarm / Protection

The complete measurement depends on both the mechanical sensing arrangement and the electrical signal path. An unstable probe mounting, incorrect sensing gap, damaged cable, converter fault, or monitoring-input problem can therefore appear as an abnormal machinery measurement.

Role in a Machinery Monitoring Architecture

The PR6423/013-030+CON011 functions as the front-end sensing and signal-conditioning section of a machinery monitoring channel.

Rotating Shaft → PR6423/013-030 → CON011 → Monitoring System → Alarm & Protection

The separate sensing and signal-conditioning stages allow technicians to isolate mechanical, sensor, converter, and monitoring-side faults during troubleshooting.

Industrial Applications

Installation and Maintenance

2. Verify the PR6423 sensor and CON011 converter configuration before installation.
3. Mount the sensor securely so that external vibration cannot change its position.
4. Position the probe relative to the conductive target according to the applicable installation requirements.
5. Verify the probe-to-target sensing gap during commissioning.
6. Confirm that the monitored target has a suitable conductive surface and geometry.
7. Route the sensor cable to minimize mechanical stress, abrasion, and other installation hazards.
8. Inspect sensor and converter connections before applying system power.
9. Check the conditioned measurement signal during commissioning for stable behavior.

Technical FAQs

What is the function of the CON011 in this combination?

The CON011 serves as the signal-conditioning stage associated with the PR6423/013-030 eddy current sensor. It processes the sensor response before the measurement is transferred to downstream monitoring equipment.

Is the PR6423/013-030+CON011 suitable for shaft monitoring?

Yes. The combination can be used in measurement channels where changes in the position of a conductive rotating shaft need to be detected for machinery monitoring or protection purposes.

Why might the measurement remain incorrect after replacing the sensor?

Replacing the probe does not eliminate other possible causes. The sensing gap, probe mounting, target condition, cable connections, CON011 operation, and downstream monitoring input should also be checked.

What is the recommended troubleshooting sequence for this sensor-converter combination?

Start at the mechanical sensing point by checking probe mounting and target clearance. Then inspect the sensor cable and connections, verify the CON011 signal-conditioning stage, and finally check the receiving machinery monitoring channel.
