FAQ
Q1: How does the PR6424/007-121 detect displacement?
A1: It uses eddy-current principles; a magnetic field is induced, and variations in the target’s conductive material change the sensor’s output voltage or current.
Q2: Can this sensor measure non-metallic targets?
A2: No, it only responds reliably to conductive metals.
Q3: What is the maximum target velocity it can measure?
A3: The sensor can reliably respond to targets moving at speeds up to several meters per second depending on the range and system configuration.
Q4: How should the sensor be mounted for optimal accuracy?
A4: Mount the sensor rigidly, with the sensing face parallel to the target surface, and maintain the recommended gap within its linear range.
Q5: Can multiple PR6424 sensors operate in close proximity?
A5: Yes, but proper shielding and separation are recommended to avoid electromagnetic interference.
Q6: What kind of output signal is typical for integration with control systems?
A6: The sensor provides either a 4–20 mA current loop or 0–10 V voltage output depending on configuration.
Q7: Is the sensor affected by temperature changes?
A7: Minor compensation is applied internally, but large temperature fluctuations may require calibration or temperature correction.
Q8: How fast is the sensor’s response time?
A8: The sensor has a response frequency up to 10 kHz, suitable for high-speed vibration monitoring.
Q9: Can it be used in explosive or hazardous environments?
A9: Not without an additional certified protective housing; consult safety standards for hazardous locations.
Q10: How do I calibrate the sensor?
A10: Calibration is performed by comparing the sensor output to known reference displacements and adjusting the system accordingly.
