Epro PR6424/113-121 Eddy Current Displacement Sensor

FAQ

Q1. What measurement function does the PR6424/113‑121 serve?
It is a non‑contact eddy current displacement sensor used to measure shaft radial or axial displacement, vibration, eccentricity, and related parameters in rotating equipment.

Q2. In what industries is this sensor commonly used?
It is typically used in power generation, oil & gas, petrochemical, pumps, compressors, turbines, and other industrial machinery monitoring applications.

Q3. What is the typical measurement range of this sensor type?
Sensors in the PR6424 family commonly provide a static displacement range of around ±2.0 mm and dynamic measurement capability up to ~1000 µm.

Q4. What kind of target surface is required for accurate measurement?
The sensor is designed for ferromagnetic steel shaft surfaces with minimum recommended diameter typically ≥ 80 mm.

Q5. How is the sensor installed on the machine?
It mounts close to the rotating shaft using an M18 × 1.5 threaded housing and connects with shielded cable to a compatible signal converter or monitoring system.

Q6. Does the sensor require a converter module to function?
Yes. The PR6424 sensor usually interfaces with a signal conditioner or dedicated converter (such as EPRO CON series) to produce usable electrical outputs for monitoring.

Q7. What environmental conditions can this sensor withstand?
PR6424 sensors are designed for harsh industrial environments, with typical operating temperatures from roughly −35 °C up to +180 °C and good shock and vibration resistance.

Q8. What is the approximate weight of the sensor?
This eddy current sensor typically weighs about 0.20 kg including approximately 1 m of cable.
