The EPRO PR6426/000-040 CON021 is a complete eddy current transducer system consisting of a PR6426 displacement probe and a CON021 signal converter. Designed for permanent installation on critical rotating equipment, the system provides precise non-contact measurement of shaft dynamic behavior and relative position.

With its large-diameter probe design and extended measuring range, the PR6426 series is particularly suited to heavy-duty turbomachinery where conventional vibration sensors may not provide direct shaft movement data. The system is commonly installed on steam turbines, gas turbines, centrifugal compressors, generators, and other high-value rotating assets to support machinery protection and condition monitoring programs.

By continuously tracking shaft vibration, axial displacement, differential expansion, and rotor eccentricity, the PR6426/000-040 CON021 enables maintenance teams to identify developing mechanical issues before they affect process reliability or equipment availability.

Non-contact eddy current sensing technology for direct shaft measurement.

Suitable for large shaft diameters and heavy rotating machinery.

Stable output across varying operating temperatures and process conditions.

High immunity to oil mist, dust, vibration, and industrial contaminants.

Fast response characteristics for capturing transient machine events.

Factory-matched probe and converter assembly for measurement consistency.

Compatible with EPRO MMS6000 and other machinery health monitoring platforms.

Supports continuous online monitoring without interrupting machine operation.

Designed for integration into turbine supervisory and protection systems.

Long operational life with minimal maintenance requirements.

Why is probe-to-target gap adjustment important during commissioning?

The eddy current measuring principle operates within a calibrated linear range. Incorrect initial gap settings may reduce measurement accuracy, limit available dynamic range, or increase susceptibility to signal saturation. Proper gap adjustment ensures optimum sensitivity and measurement stability.

Can the PR6426/000-040 CON021 be used in high-temperature turbine environments?

Yes. The probe is designed for installation near bearings and turbine sections where elevated temperatures are common. Its construction allows reliable operation under demanding thermal conditions while maintaining signal integrity and long-term measurement stability.

How does a factory-matched probe and converter improve measurement reliability?

The PR6426 probe and CON021 converter are calibrated as a complete measuring chain. This approach minimizes sensitivity deviations, enhances linearity performance, and ensures that the output signal accurately represents actual shaft displacement throughout the specified measurement range.

What operational benefits can plant operators expect from continuous shaft monitoring?

Continuous monitoring provides early warning of abnormal mechanical behavior, reduces the likelihood of catastrophic equipment failure, supports condition-based maintenance strategies, and helps maximize equipment availability while lowering lifecycle maintenance costs.

Which machine parameters are typically monitored using the PR6426/000-040 CON021?

The system is commonly configured for:

1. Relative shaft vibration

2. Axial thrust position

3. Shaft eccentricity

4. Differential expansion

5. Rotor position monitoring

6. Dynamic shaft displacement analysis
