Epro PR6424/114-121 Eddy Current Displacement Sensor

FAQ

Q1. What is the PR6424/114‑121 used for?
It is a non‑contact eddy current displacement sensor for measuring shaft vibration, displacement, eccentricity and motion in industrial rotating machinery.

Q2. What measurement range does this sensor support?
It supports a static range of ±2.0 mm and a dynamic range of 0–1,000 µm.

Q3. What are the physical dimensions of the PR6424/114‑121?
Sensor head diameter 16 mm × body length ~40 mm × cable diameter ~2.8 mm × cable length 1 m (standard, longer optional).

Q4. What thread size is used for mounting?
It uses an M18 × 1.5 threaded housing for installation near the target shaft.

Q5. What operating temperature range can this sensor handle?
The sensor operates reliably from −35 °C to +180 °C.

Q6. What materials does this sensor measure best on?
It is designed for ferromagnetic steel shafts such as 42CrMo4 and similar materials.

Q7. Does this sensor require additional electronics to use?
Yes — it typically works with a separate signal conditioner or converter (e.g., EPRO CON series) to produce a usable output for monitoring systems.

Q8. How much does the sensor weigh?
With a standard 1 m cable, it weighs around 0.20 kg.
