Product Overview

The Epro PR6423/10R-131+CON041 combines an 8 mm eddy current sensor with a CON041 eddy current signal converter to form a non-contact measurement channel for rotating machinery. The PR6423 sensor monitors relative movement between the probe and a conductive shaft or target, while the converter conditions the resulting sensor signal for compatible monitoring equipment.

This configuration can be used where shaft position, displacement, radial movement, axial movement, or vibration-related changes need to be monitored without mechanical contact. The sensor is installed close to the rotating target, allowing the measurement point to remain physically separated from the moving machine component.

The combined sensor and converter arrangement is suitable for machinery such as turbines, compressors, generators, motors, pumps, and other rotating equipment. It can be applied where a defined eddy current measurement channel is required between the machine-side sensing point and a downstream monitoring system.

During commissioning, the complete signal path should be checked rather than treating the probe as an isolated component. Probe alignment, target condition, installation relationship, cabling, CON041 operation, and compatibility with the receiving monitoring input can all affect the final measurement.

Working Principle

The PR6423/10R-131 sensor uses an eddy current sensing field to detect changes in the distance between the probe and a conductive target. As the shaft or rotor moves, the electrical response of the sensing circuit changes according to the target-to-probe relationship.

The sensor output is transferred to the CON041 signal converter, which conditions the measurement signal for the associated monitoring equipment. The conditioned signal can then be evaluated for shaft position, displacement, or vibration-related movement.

Conductive Shaft / Target → PR6423/10R-131 Sensor → CON041 Signal Converter → Monitoring Input → Machinery Monitoring System → Alarm / Protection

The complete measurement result depends on the mechanical installation and electrical signal path. Incorrect probe positioning, target-surface conditions, cable problems, converter faults, or an incompatible monitoring input can produce abnormal readings even when the sensor itself is functioning.

Role in an Epro Eddy Current Monitoring Architecture

The PR6423/10R-131+CON041 occupies the sensing and signal-conditioning stages of an Epro eddy current monitoring architecture. The PR6423 sensor establishes the physical measurement point, while the CON041 provides the corresponding signal-conditioning interface for the downstream monitoring system.

Rotating Shaft → PR6423/10R-131 → CON041 → Monitoring Input → Machinery Monitoring System → Alarm / Protection

The sensor and converter should be evaluated as one configured measurement path, while the converter output must still be matched to the receiving monitoring equipment.

Industrial Applications

Installation and Maintenance

1. Verify the complete PR6423/10R-131+CON041 part number before installation or replacement.
2. Confirm compatibility between the PR6423/10R-131 sensor, CON041 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 CON041 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 is the role of the CON041 in the PR6423/10R-131+CON041 configuration?

The CON041 provides the signal-conditioning stage between the PR6423/10R-131 sensor and the downstream monitoring equipment. It allows the sensor response to be processed for use by a compatible monitoring input.

Does the 8 mm sensor diameter determine the required installation gap?

No. The sensor head diameter identifies the physical sensing configuration and should not be used as the installation-gap specification. The required probe-to-target relationship must be established from the applicable measurement-system requirements.

What should be checked if the measurement changes after machine startup?

Check the probe mounting, alignment, target condition, and probe-to-target relationship first. Then inspect the sensor cable, CON041 connections, converter operation, and receiving monitoring input for possible signal-path problems.

Can the PR6423/10R-131 sensor be paired with a different converter?

A different converter should not be substituted solely because it is part of the PR6423 family. The sensor configuration, converter characteristics, cable arrangement, and receiving monitoring equipment should be verified as a complete measurement channel before substitution.
