FAQ
Q1: What is the primary measurement principle of the PR6423/000-011 sensor?
A1: It uses the eddy-current principle, where induced currents in the conductive shaft material create a measurable impedance change proportional to displacement.
Q2: Which signal converters are compatible with this sensor?
A2: The sensor is typically used with CON011 and CON021 signal converters, providing signal conditioning for protection and monitoring systems.
Q3: Can the sensor be applied for both radial and axial displacement measurements?
A3: Yes, it can measure both radial shaft vibration and axial displacement, depending on installation orientation.
Q4: How does the sensor handle electromagnetic interference (EMI)?
A4: The integrated shielding and cable design minimize susceptibility to EMI, ensuring stable signal transmission.
Q5: What type of output signal does the sensor generate?
A5: The sensor itself generates an analog voltage variation, which is processed by a converter to deliver a conditioned output suitable for monitoring systems.
Q6: Is the sensor suitable for use in hazardous industrial environments?
A6: Yes, when paired with appropriate intrinsically safe barriers or certified converters, it can be used in hazardous zones.
Q7: What is the typical frequency response of this sensor?
A7: It offers a frequency response from DC up to around 10 kHz, depending on the setup and converter used.
Q8: How is the calibration performed for this model?
A8: Calibration is typically performed using reference displacement targets and adjusting the converter settings according to factory calibration curves.
Q9: Does the sensor support continuous monitoring in high-speed rotating equipment?
A9: Yes, it is specifically designed for continuous monitoring of high-speed rotating machinery such as turbines and compressors.
Q10: What is the effect of target material on measurement performance?
A10: The sensor is calibrated for metallic conductive surfaces (typically steel). Variations in material conductivity can influence sensitivity and must be accounted for.
