FAQ
Q1: What is the principle behind the PR6423/000-030 sensor?
The sensor works on the eddy-current principle, where a magnetic field induces eddy currents in the conductive target, and changes in these currents are used to determine the distance or vibration amplitude.
Q2: Which monitoring systems are compatible with this sensor?
It is fully compatible with Epro and Emerson monitoring systems such as MMS 6000, PR6426 converter units, and CON0x signal conditioners.
Q3: What type of signal output does the PR6423/000-030 provide?
It provides a voltage output proportional to the displacement or vibration of the monitored surface.
Q4: Can this sensor operate in environments with strong electromagnetic fields?
Yes, it is designed with excellent EMI shielding to ensure stable performance in environments with strong electromagnetic interference.
Q5: How is the sensor calibrated for accurate readings?
The sensor is factory-calibrated to specific target materials and gaps, and calibration data are maintained through the associated converter unit.
Q6: What is the recommended mounting method for this sensor?
It is typically mounted in a threaded holder or bracket, ensuring proper alignment and air gap between the sensor and the target shaft.
Q7: Can the sensor be used for both vibration and axial displacement monitoring?
Yes, it can measure both radial vibration and axial displacement depending on installation orientation and configuration.
Q8: What is the linearity specification of the PR6423/000-030?
The linearity is typically within ±1% of the full-scale measurement range.
Q9: Does cable length affect sensor accuracy?
Yes, cable length can affect calibration and signal integrity; therefore, standard lengths are recommended unless recalibrated with the corresponding converter.
Q10: Is this sensor suitable for high-temperature applications?
Yes, it supports continuous operation up to +180°C, making it ideal for high-temperature environments like turbines and compressors.
