Epro PR6453/201-SDR Eddy current non‑contact displacement and vibration sensor

FAQ

Q1: What is the PR6453/201‑SDR sensor used for?
It is a compact, non‑contact eddy current proximity sensor used to measure shaft displacement, position, and vibration in rotating machinery.

Q2: What measurement technology does this sensor use?
It employs eddy current induction to detect changes in distance between the sensor tip and a conductive metal (ferromagnetic) target.

Q3: What is the typical physical size of the PR6453/201‑SDR?
The sensor has a small Ø12.5 mm tip with an approximate 75–120 mm body length, suitable for tight installation spaces.

Q4: What is the measurement range of this sensor?
It provides a typical linear range around ±1 mm from the nominal air gap.

Q5: What materials are compatible with the sensor?
The device is designed to work best with ferromagnetic steels like 42CrMo4 or similar conductive shafts.

Q6: What temperature environments can the PR6453/201‑SDR handle?
It typically operates from around −35 °C up to ~180 °C, with cable sections tolerating up to ~200 °C.

Q7: Is a signal converter required to use this sensor?
Yes — output from the eddy current probe typically requires a signal conditioner (like EPRO CON series) to interface with monitoring systems.

Q8: What types of machinery is this sensor suited for?
It is commonly used in turbines, compressors, generators, pumps, and other industrial rotating equipment for displacement and vibration monitoring purposes.
