The Epro PR6424/003-010+CON021 16 mm Eddy Current Sensor is an industrial sensing component intended for non-contact displacement measurement and machinery condition monitoring applications. Eddy current sensing technology is commonly used in industrial environments where accurate monitoring of the relative position or movement of conductive metal targets is required.
In rotating machinery, displacement measurements can help engineers assess shaft movement, monitor mechanical clearances, and identify changes in equipment operating conditions. When integrated with suitable signal conditioning and monitoring equipment, an eddy current sensor can contribute to predictive maintenance, equipment diagnostics, and machinery protection strategies.
The PR6424/003-010+CON021 is specified with a 16 mm sensor head diameter and a total stated weight of 0.32 kg. The complete model designation should be retained when identifying or replacing the component. The “+CON021” suffix forms part of the supplied product designation and should not be disregarded when checking replacement compatibility or ordering spare parts.
The sensor should be evaluated as part of a complete measurement system. Its performance depends on the associated electronics, cable arrangement, target material, installation geometry, calibration, and monitoring-system requirements. Matching only the sensor head diameter is not sufficient to establish interchangeability.

The physical specifications above are based on the supplied product information. Detailed electrical and measurement parameters should be confirmed against the technical documentation for the exact model and associated components.
An eddy current sensor operates by generating an alternating electromagnetic field near a conductive target. When the target enters this field, electrical currents are induced in its surface. These currents affect the electromagnetic response of the sensing system.
As the distance between the sensor head and the target changes, the response changes accordingly. With compatible signal conditioning and proper calibration, the system can convert these changes into a displacement-related measurement.
Because the sensor does not require direct contact with the target, it avoids the friction and contact wear associated with mechanical measurement devices. This makes eddy current technology useful in applications involving continuous monitoring of moving machinery components.
In a typical rotating-equipment application, the sensor is mounted close to a suitable conductive surface. Movement of the target relative to the sensor changes the measured gap.
Depending on the configuration of the complete measurement system, the resulting data may support monitoring of:
The specific measurement range and performance characteristics of the PR6424/003-010+CON021 should be verified before it is assigned to a particular monitoring duty.
The full model designation, including “+CON021,” should be used when checking the product against an existing installation. The suffix may identify a particular configuration or associated component, but its precise meaning and the contents of the supplied assembly should be confirmed from the applicable product documentation.
Before commissioning, verify the sensor, cable or connection arrangement, signal conditioning equipment, and monitoring channel as a complete system.
The Epro PR6424/003-010+CON021 can be considered for applications requiring non-contact displacement measurement. In a machinery monitoring architecture, the sensor detects changes in the position of a suitable target, while associated electronics process the measurement and provide it to the monitoring system.
A typical measurement chain may include:
The actual architecture depends on the application and installed equipment. The sensor should not be assumed to connect directly to a PLC or provide an independent protection function without verifying its output characteristics and system requirements.
When used alongside vibration, temperature, pressure, speed, and other operating measurements, displacement data can help maintenance personnel evaluate changes in machine condition and investigate potential mechanical problems.
Turbines operate under demanding mechanical and thermal conditions. Displacement measurements can help engineers observe shaft movement and evaluate changes in rotating equipment behavior.
Before using the PR6424/003-010+CON021 in a turbine installation, confirm the required measurement range, target geometry, operating environment, mounting arrangement, and compatibility with the installed monitoring system.
Industrial compressors often run continuously and experience changing process loads. Non-contact displacement measurements can contribute to the assessment of shaft movement and mechanical stability.
The sensor must be matched to the compressor’s measurement requirements and integrated with suitable signal conditioning and monitoring equipment. Correct installation and calibration are important for reliable trend analysis.
In suitable pump and motor installations, displacement sensing can help engineers observe changes in shaft position or relative movement. These measurements can complement vibration analysis, bearing temperature monitoring, and other maintenance techniques.
The mounting arrangement should provide stable positioning and sufficient clearance from moving components. An unstable mounting bracket or unsuitable sensor-to-target gap can affect measurement quality.
Power generation facilities use monitoring systems to assess the operating condition of turbines, generators, and auxiliary machinery. Eddy current sensors can form part of these systems when non-contact displacement measurement is required.
Reliable integration depends on selecting the correct sensor configuration, confirming the associated electronics, and commissioning the measurement channel according to the application requirements.
Process industries rely on rotating machinery for continuous production. Displacement measurement can provide additional information for evaluating equipment behavior and planning maintenance activities.
Before selecting the sensor for a process plant, verify the environmental conditions, target material, measurement range, and complete system compatibility.
Correct installation is essential for obtaining stable and repeatable measurements.
Confirm that the product designation is Epro PR6424/003-010+CON021. Retain the full suffix when recording inventory details, preparing purchase orders, and evaluating replacement parts.
Compare the supplied component with the original system documentation. Do not assume that the PR6424/003-010 without the suffix is automatically interchangeable with the complete model specified here.
Inspect the sensor housing, cable, connector, and mounting surfaces for visible damage. Confirm that the installation location provides sufficient space and allows secure mounting.
The sensor must be positioned so that it cannot contact the moving target during normal operation or expected mechanical movement. Follow the applicable specifications for mounting clearance and alignment.
Eddy current measurement depends on the interaction between the sensor’s electromagnetic field and a conductive target. The target material, dimensions, surface condition, and geometry can influence the measurement response.
Confirm that the target is suitable for the intended sensing arrangement and that the installation gap falls within the approved operating range.
Use the specified cable and connection arrangement for the complete sensor configuration. Inspect the wiring for damaged insulation, loose connections, contamination, and excessive mechanical strain.
In electrically noisy environments, follow established instrumentation wiring practices. Where appropriate, route measurement cables separately from high-current power cables to reduce interference.
Do not substitute cables or connectors solely because their physical dimensions appear similar. Electrical characteristics and cable configuration may affect the performance of the complete measurement system.
Check that the associated signal conditioning equipment is suitable for the exact sensor configuration. Verify the required connections, calibration data, supply conditions, and output characteristics.
If the measurement is sent to a PLC, DCS, or machinery protection system, confirm that the receiving input supports the signal provided by the associated electronics. Direct connection should not be assumed.
After installation, perform the commissioning procedure specified for the complete system.
Recommended checks include:
All testing should follow site safety procedures and be performed by qualified personnel. Machinery protection functions should remain subject to approved plant procedures throughout commissioning.
Possible causes:
Recommended actions:
Inspect the cable and connectors, verify the documented wiring arrangement, and check the status of the signal conditioning equipment. If an approved diagnostic procedure is available, use it to determine whether the problem originates in the sensor, connection assembly, conditioning electronics, or monitoring channel.
Check the complete configuration before replacing the sensor.
Possible causes:
Recommended actions:
Inspect the mounting arrangement and cable condition. Compare the measurement with other machinery data to determine whether the fluctuation corresponds to real equipment movement.
Review the calibration and signal conditioning configuration before concluding that the sensor has failed.
Possible causes:
Recommended actions:
Verify the installation geometry, calibration procedure, target characteristics, and monitoring-system settings. Confirm that the full model number and associated connection arrangement match the requirements of the original system.
A machinery monitoring alarm does not necessarily mean the sensor has failed. It may indicate genuine mechanical movement, signal interruption, incorrect scaling, an unsuitable alarm threshold, or a problem elsewhere in the measurement chain.
Review the channel status, measurement trends, alarm configuration, and other relevant operating data. Follow the plant’s established protection procedures before changing any settings.
Do not disable protection functions or adjust alarm thresholds simply to suppress an unexplained alarm.
If the sensor or its associated connection components show visible damage, or if abnormal readings continue after the installation and electronics have been checked, further diagnostics may be required.
Use an approved procedure appropriate to the complete configuration. Avoid applying arbitrary voltage, resistance, or continuity tests unless they are explicitly permitted by the relevant technical instructions.
The PR6424/003-010+CON021 should be assessed as part of the complete measurement chain.
