製品紹介
The Epro PR6424/006‑030 paired with the CON021 converter constitutes a highly accurate, non‑contact eddy current sensor system designed for shaft displacement and vibration measurement in rotational machinery. Featuring a 16 mm probe tip diameter, this model delivers excellent sensitivity and linearity, suitable for large‑shaft applications in turbines, compressors, pumps and fans.
The CON021 module amplifies and conditions the raw sensor signal into a standard analog voltage output compatible with monitoring platforms such as VM600, MMS6000, CSI 6500, and similar systems. Engineered to withstand harsh industrial environments, this sensor system is widely used within energy, petrochemical and heavy‑equipment industries for condition monitoring and machine protection.

FAQ
-
What is the nominal sensitivity and linearity / this sensor system?
Approximately 4 V/mm with linearity within ±1.5 %. -
What is the static measurement range supported?
±2.0 mm static range is supported; dynamic monitoring typically up to 1000 µm. -
What frequency range does the sensor handle reliably?
Up to approximately 8 kHz, sufficient for typical shaft vibration monitoring. -
Which thread type is standard for mounting?
M18×1.5 or ¾‑16 UNF depending on application and shaft size. -
Is this sensor suitable for high‑speed rotational environments?
Yes—designed for continuous vibration up to 100 m/s² and shock up to 500 m/s². -
What output formats are supported via the CON021 converter?
Common outputs include 0–10 V DC or 4–20 mA analog signals, depending on wiring and calibration. -
How is the sensor calibrated to the target surface?
Calibration must be carried out on a ferromagnetic steel target (e.g. DIN 1.7225) with specified gap and converter setup. -
How is electromagnetic interference handled?
The sensor and converter cable are shielded; proper grounding practice further ensures EMI resilience. -
Can this probe measure both radial and axial displacement?
Yes, orientation / mounting determines whether radial or axial movement is measured. -
What is the recommended shaft diameter for safe operation?
Minimum shaft diameter is approximately 80 mm to ensure adequate target sensing area.
