Epro PR6426/010-040 Eddy current non‑contact displacement and vibration sensor

FAQ

Q1: What is the PR6426/010‑040 sensor mainly used for?
It is used for non‑contact measurement of shaft displacement, vibration, and position in large rotating machinery including turbines, compressors, pumps, and fans.

Q2: What measurement principle does this sensor use?
The probe operates using eddy current technology, sensing electromagnetic changes as the distance between the probe and target varies.

Q3: What is the typical measuring range?
The sensor provides a linear displacement range of approximately ±4.0 mm around the nominal air gap.

Q4: What materials can be measured effectively with PR6426/010‑040?
It works best with conductive ferromagnetic materials such as alloy steel shafts like 42CrMo4.

Q5: What temperature conditions can the sensor tolerate?
The device operates from about −35 °C to 180 °C, with short allowed excursions up to approximately 200 °C.

Q6: What shaft size is recommended for accurate measurement?
For reliable readings, a shaft diameter of at least 200 mm is recommended.

Q7: What environmental resistance features does this sensor have?
It withstands industrial shock/vibration around 5 g and pressure up to ~6500 hPa, suitable for harsh environments.

Q8: Does the PR6426/010‑040 require a signal converter?
Yes, it typically works with compatible eddy current signal converters (e.g., CON011, CON021) for conditioned outputs.
