FAQ
Q1: What is the measuring principle of the PR6423/01M-010 sensor?
A1: The sensor operates based on the eddy-current principle, where an alternating magnetic field induces eddy currents on a conductive surface, allowing accurate measurement of displacement or vibration.
Q2: Can the sensor be used with other converters besides CON021?
A2: While it is optimized for CON021, it can interface with compatible converters that support similar calibration and sensitivity characteristics.
Q3: How is signal linearity ensured across the measuring range?
A3: The sensor and converter pair (PR6423 + CON021) are factory-calibrated together to ensure linear output over the specified range.
Q4: What factors influence the accuracy of displacement measurement?
A4: Factors such as target material conductivity, temperature changes, and cable length can slightly affect measurement accuracy.
Q5: Is the sensor suitable for high-temperature applications?
A5: Yes, the PR6423/01M-010 is rated for continuous operation up to +180°C.
Q6: Can the sensor operate in oily or contaminated environments?
A6: Yes, it features an IP67-rated stainless steel body, providing excellent resistance to oil, dirt, and moisture.
Q7: How should grounding and shielding be handled during installation?
A7: Proper grounding and cable shielding are critical to minimize electromagnetic interference and maintain accurate signal output.
Q8: What is the recommended gap between the sensor and the target?
A8: The nominal gap typically ranges between 1 mm and 2 mm, depending on calibration and target material.
Q9: What type of signal output does the sensor provide?
A9: The sensor outputs a voltage signal proportional to the distance between the probe tip and the target surface.
Q10: Can the sensor be replaced or recalibrated independently of the converter?
A10: It is recommended to replace or calibrate the probe and converter as a matched pair to maintain measurement precision.
