FAQ
Q1: How does the sensor detect displacement?
The sensor uses eddy-current principles where an alternating magnetic field induces currents in a conductive target. Variations in distance change the induced current, which is converted into a voltage signal.
Q2: Can the sensor be used in high-speed rotating machinery?
Yes, the sensor has a frequency response suitable for measurements up to 10 kHz, making it compatible with high-speed rotors.
Q3: What type of output signal does the PR6424/007-021 provide?
It provides a differential voltage output proportional to the displacement of the target.
Q4: Is the sensor compatible with standard signal conditioning units?
Yes, it can be connected to standard Epro signal conditioners or third-party units that accept eddy-current sensor inputs.
Q5: Can the sensor operate in extreme temperatures?
Yes, it is rated for operation from -40°C to +125°C.
Q6: How is the sensor affected by electromagnetic interference (EMI)?
The sensor’s shielded twisted-pair cable design reduces susceptibility to EMI in industrial environments.
Q7: What materials can the target be made of?
The target should be a conductive material, typically ferrous or non-ferrous metals, suitable for eddy-current interaction.
Q8: Can this sensor be used in oil or wet environments?
Yes, it has an IP65 or higher rating when installed properly, offering protection against dust and water spray.
Q9: Is calibration required before use?
While factory calibration is provided, field calibration is recommended to ensure accuracy based on installation geometry.
Q10: How long is the standard cable, and can it be extended?
Standard cables range from 1–5 meters. Extension is possible with shielded cables, but signal integrity should be maintained using proper wiring practices.
