FAQ
Q1: What type of signal conditioning unit is required for the PR6423/13R-010+CON021 sensor?
A1: It is specifically designed to operate with the Epro CON021 converter, which provides appropriate excitation and signal linearization.
Q2: How does the sensor detect vibration or displacement?
A2: The sensor generates an electromagnetic field; when a conductive target moves within this field, eddy currents are induced, and the resulting impedance change is converted into a distance signal.
Q3: Can this sensor be used in high-temperature zones near turbines?
A3: Yes, the PR6423/13R-010 model can operate in environments up to +180°C without degradation in accuracy.
Q4: Is the sensor sensitive to target material type?
A4: Yes, it is optimized for conductive metallic targets such as steel. Variations in material conductivity can slightly affect calibration and output linearity.
Q5: What is the recommended gap or measuring range for the 8 mm probe?
A5: The recommended linear measuring range is typically 0–2 mm to ensure optimal performance and signal linearity.
Q6: How is the sensor calibrated with the CON021 unit?
A6: Calibration is performed using a reference target and the CON021’s calibration module to ensure the output voltage accurately reflects the displacement distance.
Q7: Can the sensor detect both static and dynamic displacement?
A7: Yes, it can measure both static position changes and dynamic vibration signals due to its wide frequency response range.
Q8: What is the effect of cable length on measurement accuracy?
A8: Excessive cable length may affect signal integrity. The standard 10-meter cable ensures minimal signal loss when used with the CON021 converter.
Q9: Is electromagnetic interference (EMI) a concern for this sensor?
A9: The sensor is well-shielded against EMI; however, in high-EMI environments, proper grounding and cable shielding are recommended.
Q10: Can multiple PR6423 sensors be connected to the same monitoring system?
A10: Yes, multiple sensors can be integrated into one monitoring network when each is connected via its dedicated CON021 converter channel.
