Epro PR6426/010-140 Eddy current non‑contact displacement and vibration sensor

FAQ

Q1: What is the PR6426/010‑140 sensor used for?
It provides non‑contact measurement of shaft displacement, vibration, and position in large rotating machinery.

Q2: What measurement principle does the PR6426/010‑140 use?
It uses eddy current technology to sense distance changes between the probe tip and a conductive target.

Q3: What is the typical measurement range of this sensor?
The sensor offers a linear measurement range of approximately ±4.0 mm from the nominal air gap.

Q4: What materials can this sensor measure effectively?
It is optimized for conductive ferromagnetic materials like steel shafts (e.g., 42CrMo4).

Q5: What temperature environments can the sensor withstand?
The sensor operates from −35 °C to about 180 °C, with short excursions up to 200 °C.

Q6: What shaft diameter is recommended for accurate results?
For reliable readings, the shaft diameter should be at least 200 mm.

Q7: What environmental resistances does this sensor provide?
It is built to withstand industrial shock/vibration of ~5 g and pressure up to ~6,500 hPa.

Q8: Does the PR6426/010‑140 require a signal converter?
Yes, it typically works with compatible eddy current signal converters (e.g., CON011 or CON021) to condition the output.
