Product Overview
The Epro PR6423/01M-030+CON011 combines an 8 mm eddy current sensor with an eddy current signal converter for non-contact measurement of shaft position and movement in rotating machinery. The combined assembly forms a defined measurement channel from the machine-side sensing point to the conditioned output used by the monitoring system.
The sensor is installed close to a conductive rotating target, such as a turbine shaft, compressor rotor, generator shaft, or other precision-machined surface. Changes in the distance between the sensor tip and target produce corresponding changes in the eddy current sensing circuit.
The CON011 signal converter handles the sensor-side signal conditioning so that the measurement can be transferred to compatible monitoring or control equipment. This arrangement is useful where the sensor and signal-conditioning stage need to operate together as part of a machinery monitoring channel.
For maintenance work, the sensor and converter should be treated as one configured measurement path while still checking their connections to the downstream monitoring system. Probe alignment, target condition, cabling, converter operation, and the final monitoring input can all influence the observed signal.

Working Principle
The PR6423 sensor generates an eddy current sensing field at the probe tip. When a conductive shaft or target enters this field, the electrical response changes according to the relative distance between the target and sensor.
The sensor signal is transferred to the CON011 signal converter, where the sensing response is conditioned into a usable measurement signal for the associated monitoring equipment. The downstream system can then use this information for shaft displacement, position, vibration-related analysis, alarm, or protection functions.
Conductive Shaft / Target → PR6423/01M-030 Sensor → CON011 Signal Converter → Monitoring System → Alarm / Protection
The measurement depends on the complete sensor channel. Probe-to-target gap, shaft surface condition, probe alignment, cable integrity, converter operation, and downstream input compatibility should therefore be considered together when commissioning or troubleshooting.
Role in an Epro Eddy Current Monitoring Architecture
The PR6423/01M-030+CON011 occupies both the sensing and signal-conditioning stages of the machinery monitoring chain. The probe establishes the physical measurement point, while the converter prepares the resulting signal for use by the monitoring system.
Rotating Shaft → PR6423 Eddy Current Sensor → CON011 Signal Converter → Machinery Monitoring System → Alarm / Protection
| System Element | Function |
|---|---|
| Rotating Shaft / Target | Provides the conductive surface being monitored |
| PR6423/01M-030 | Detects changes in target-to-probe distance |
| CON011 | Conditions and converts the sensor response for system use |
| Monitoring System | Evaluates shaft position, displacement, or vibration information |
| Alarm / Protection System | Generates configured warning or protective responses |
| Control / Automation System | Uses monitoring information for machine operation or protection |
The combined sensor and converter should be installed as a compatible measurement channel, with the downstream interface verified against the requirements of the monitoring system.

Installation and Maintenance
- Verify the complete PR6423/01M-030+CON011 part number before installation.
- Confirm compatibility between the combined sensor/converter channel and the intended monitoring equipment.
- Isolate the rotating machinery and follow the applicable site safety procedure before working on the installation.
- Inspect the sensor tip for contamination, impact damage, or abnormal wear.
- Verify the mounting arrangement and ensure that the sensor can be positioned correctly relative to the conductive target.
- Establish the required probe-to-target relationship according to the associated Epro measurement system requirements.
- Maintain proper probe alignment and ensure that the mounting structure remains mechanically secure.
- Inspect sensor and converter cabling for damage, excessive bending, loose connections, or environmental exposure.
- Check the CON011 converter connections and confirm that the signal path is correctly terminated.
- Verify the measurement output after installation and compare it with expected machine conditions.
- If the signal is unstable, inspect the probe position, target surface, wiring, converter, and downstream monitoring input before replacing components.
- After replacement, perform a complete measurement-channel and monitoring-system functional test before returning the machinery to normal operation.

Technical FAQs
Why is the CON011 included with the PR6423/01M-030 in this configuration?
The CON011 forms the signal-conditioning stage of the measurement channel. It processes the response from the PR6423 sensor so that the resulting measurement can be transferred to compatible downstream monitoring equipment.
What installation condition has the greatest effect on measurement quality?
The probe-to-target relationship is critical. Incorrect gap, poor alignment, an unsuitable target surface, or mechanical movement of the mounting arrangement can change the measured response even when the sensor and converter are functioning normally.
Can the combined assembly be connected to any machinery monitoring input?
Not automatically. The output characteristics of the CON011 must match the input requirements of the receiving monitoring equipment. The complete sensor, converter, cabling, and monitoring-system configuration should be verified before installation.
How can a fault be isolated between the PR6423 sensor and CON011 converter?
Check the probe installation and target relationship first, then inspect the sensor cable and converter connections. If the mechanical installation and wiring are correct, the converter output can be checked against the expected measurement behavior before investigating the downstream monitoring input.
