Deskripsi
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.

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.
