Epro PR6423/016-100 8mm Eddy Current Probe Sensor Unit

General Description

The Epro PR6423/016-100 is an 8 mm eddy-current proximity probe developed for continuous, non-contact monitoring of shaft movement, vibration behavior, and positional deviation in high-speed rotating machinery. It operates as part of a complete measurement chain with external signal conditioning units, providing reliable data for protection and condition monitoring systems.

Its eddy-current sensing principle ensures stable operation without physical contact, making it suitable for long-term deployment in demanding industrial environments.

Technical Specifications

Engineering Characteristics

• Non-contact measurement eliminates mechanical wear and drift

• Stable output under high vibration and high rotational speed conditions

• High signal fidelity for dynamic shaft movement analysis

• Designed for integration into protection and monitoring architectures

• Suitable for continuous operation in harsh thermal and mechanical environments

Application Scope

• Gas and steam turbine monitoring

• Compressor shaft vibration and axial position tracking

• Generator and large motor condition monitoring

• Gearbox displacement and alignment supervision

• Predictive maintenance systems for rotating assets

Installation & System Notes

The probe is not a standalone transmitter. It requires a dedicated eddy-current driver or converter module to condition the signal into industrial outputs (such as 4–20 mA or voltage signals).

Proper installation requires:

• Controlled air gap calibration

• Stable mounting to avoid mechanical resonance influence

• Correct material targeting (best performance on steel-based shafts)

FAQ

Q1: Can this probe operate independently without a converter?
No. It must be paired with an external signal conditioning system such as CON041 or equivalent.

Q2: What type of material is optimal for measurement?
Best performance is achieved on ferromagnetic steel surfaces. Non-ferrous materials may reduce sensitivity.

Q3: Is this suitable for high-speed rotating equipment?
Yes. Its fast response and eddy-current principle make it suitable for high RPM machinery monitoring.
