FAQ
Q1: What is the measuring principle of the PR6424/002-121?
A1: It operates on the eddy-current principle, where an alternating magnetic field induces eddy currents in the conductive shaft surface, and the sensor measures displacement based on impedance variation.
Q2: Can the sensor detect both static and dynamic displacement?
A2: Yes, it can measure static shaft position (DC component) as well as dynamic vibration signals (AC component).
Q3: What type of materials can the sensor measure effectively?
A3: It is designed to measure ferromagnetic and conductive materials, with best performance on metallic shaft surfaces.
Q4: How does cable length affect accuracy?
A4: The cable length is factory-calibrated. Using the specified cable length ensures accuracy; deviations may require recalibration with a matching driver.
Q5: What is the typical output sensitivity of the sensor?
A5: The standard sensitivity is approximately 8 mV/µm when paired with the matching proximity driver.
Q6: Is the sensor compatible with all Epro proximity drivers?
A6: It is optimized for use with the Epro CON0x and CON9xx series proximity probe drivers for best accuracy and linearity.
Q7: How does temperature variation affect sensor performance?
A7: The sensor is temperature compensated within its specified operating range, ensuring stable measurements in varying thermal environments.
Q8: What is the maximum vibration frequency the sensor can capture?
A8: It supports frequency response up to 10 kHz, which covers most industrial machinery vibration monitoring requirements.
Q9: Can this sensor be used in hazardous environments?
A9: Yes, when paired with appropriate intrinsically safe barriers or certified drivers, it can be applied in ATEX/IECEx hazardous zones.
Q10: What maintenance does the PR6424/002-121 require?
A10: Minimal maintenance is required due to its non-contact design; periodic inspection of mounting, cable integrity, and system calibration is sufficient.
