Epro PR6425/010-A20 Eddy current non‑contact displacement and vibration measurement sensor

FAQ

Q1: What measurement applications is the PR6425/010‑A20 sensor designed for?
It is intended for non‑contact monitoring of shaft vibration, displacement, and position on rotating machinery.

Q2: What sensing technology does this probe use?
The sensor uses eddy current technology, detecting changes in distance between the probe and a conductive target surface.

Q3: What are the physical dimensions and size of the sensor?
The probe has a 16 mm diameter, about 69 mm length with M18×1.5 mounting thread; cable length varies by order.

Q4: What materials can the PR6425/010‑A20 measure effectively?
It performs best with conductive ferromagnetic materials such as alloy steels like 42CrMo4 or similar.

Q5: What temperature range can the sensor withstand?
It generally supports environments from about –35 °C up to ~380 °C (depending on cable and configuration).

Q6: What shaft size is recommended for accurate measurements?
A minimum shaft diameter of around 80 mm is recommended for proper measurement stability.

Q7: What environmental resistances does the sensor provide?
It typically handles shock/vibration around 5 g and pressures up to ~2000 hPa, with stainless steel housing and PTFE cable.

Q8: Does the PR6425/010‑A20 require a signal converter?
Yes, to condition the raw probe signal into usable output, it is usually paired with a compatible converter (e.g., CON021 series).
