Product Overview

The Epro PR6423/01C-010+CON021 8mm Eddy Current Sensor+Eddy Current Signal Converter combines a PR6423 Series eddy current sensor with a CON021 signal converter for non-contact measurement of conductive targets in rotating machinery. The combination covers the sensing and signal-conditioning stages required to transfer shaft movement information to downstream monitoring equipment.

The PR6423/01C-010 sensor is positioned near the monitored conductive shaft or target. Relative movement changes the eddy current response at the sensing head, while the CON021 processes the sensor response into a usable signal for the associated monitoring system.

This configuration is suitable for turbines, compressors, generators, motors, pumps, expanders, and other rotating equipment where shaft displacement, axial position, radial movement, or vibration-related motion needs to be monitored without physical contact.

During maintenance, the sensor and converter should be evaluated as a complete measurement channel. Probe positioning, target characteristics, installation gap, mounting stability, wiring, converter operation, and monitoring-input compatibility can all affect the final signal.

Working Principle

The PR6423/01C-010 sensing element generates an electromagnetic field around the monitored target. When a conductive shaft moves relative to the sensing head, the eddy current response changes according to the target-to-sensor relationship.

The CON021 Eddy Current Signal Converter receives the sensor response and converts it into a signal suitable for the downstream monitoring system. The resulting measurement can then be evaluated for shaft position, displacement, or vibration-related movement.

Rotating Shaft / Conductive Target → PR6423/01C-010 Sensor → CON021 Signal Converter → Machinery Monitoring System → Alarm / Protection

The sensor measures relative movement between the sensing head and target. Unwanted movement of the sensor mounting can therefore influence the output. Mechanical stability, correct probe positioning, target condition, and converter operation should be checked together when commissioning or troubleshooting the measurement channel.

Role in an Epro Eddy Current Monitoring Architecture

The PR6423/01C-010+CON021 occupies both the field sensing and signal-conversion stages of the monitoring channel. The sensor detects the physical movement at the machine, while the CON021 prepares the response for the receiving monitoring equipment.

Rotating Machinery → PR6423/01C-010 → CON021 → Monitoring Input → Machinery Protection / Control

The complete sensor, converter, wiring, and monitoring input should be considered when diagnosing abnormal readings.

Industrial Applications

Installation and Maintenance

1. Confirm the complete PR6423/01C-010+CON021 configuration before installation.
2. Verify compatibility between the PR6423 sensor, CON021 converter, monitoring input, and associated wiring.
3. Isolate the monitored machinery and follow applicable safety procedures before working near rotating equipment.
4. Inspect the sensor head, converter, connectors, and cable assembly for visible damage.
5. Ensure the sensor mounting arrangement is mechanically secure and resistant to unwanted movement.
6. Position the sensing head correctly relative to the conductive shaft or target surface.
7. Establish the required sensor-to-target gap according to the applicable monitoring-system requirements.
8. Route the sensor wiring to minimize mechanical stress, excessive bending, and avoidable electrical interference.
9. Check sensor and converter connections for secure attachment and signs of contamination.
10. Verify the CON021 output and receiving monitoring input during commissioning.
11. If the signal becomes unstable, check probe position, target condition, cable integrity, converter operation, and monitoring input before replacing components.
12. After replacement, verify the complete sensor-to-monitoring path and confirm normal machinery monitoring operation before returning the equipment to service.

Technical FAQs

What does the PR6423/01C-010 contribute to the combined assembly?

The PR6423/01C-010 provides the non-contact eddy current sensing function. It detects changes in the relative position of a conductive target and supplies the corresponding sensing response to the CON021 converter.

Why is the CON021 considered part of the measurement chain?

The sensor response requires appropriate signal handling before it can be used by downstream monitoring equipment. The CON021 provides the associated conversion stage, so its compatibility and operating condition should be checked together with the sensor.

What can cause an incorrect shaft displacement reading even when the sensor is functional?

A mechanically displaced probe, incorrect sensor-to-target gap, unsuitable target condition, damaged cable, or converter problem can all affect the measured result. The mechanical and electrical portions of the measurement chain should therefore be checked together.

When is this combined sensor and converter configuration preferable to replacing only the sensor?

A combined configuration is useful when the installed monitoring channel uses the specified sensor and CON021 pairing. Before replacement, the complete part designation and existing system arrangement should be compared to ensure that the replacement matches the intended measurement chain.
