FAQ
Q1: What type of signal does the PR6424/009-100 output?
A1: The sensor outputs an analog voltage proportional to the shaft displacement when connected with its proximitor driver.
Q2: Is the sensor polarity-sensitive during installation?
A2: No, but correct alignment with the shaft surface is required for accurate readings.
Q3: Can this sensor be used for both radial and axial displacement monitoring?
A3: Yes, it supports both radial and axial applications depending on the installation configuration.
Q4: What drivers are recommended for this sensor?
A4: It is fully compatible with Epro CON021, CON041, and CON051 drivers.
Q5: Does the sensor require calibration after installation?
A5: The sensor itself does not, but the complete measurement chain (sensor + driver + cable) should be calibrated.
Q6: What is the typical cable length supported without affecting accuracy?
A6: Standard configurations support up to 9 meters, though longer lengths may require special calibration.
Q7: How does temperature affect sensor accuracy?
A7: The sensor is designed with thermal compensation to minimize drift within its operating temperature range.
Q8: Can the sensor detect rotor-to-stator rubs or impacts?
A8: Yes, with its fast frequency response, it can capture sudden displacement events such as rubs or impacts.
Q9: What protection measures are built into the sensor against electrical interference?
A9: The sensor uses shielded coaxial cables and internal shielding to minimize electromagnetic interference.
Q10: Is it possible to connect the sensor directly to a monitoring system without a driver?
A10: No, the sensor requires a proximitor driver to condition and linearize the signal for monitoring systems.
