FAQ
Q1: How does the sensor achieve linearity over its operating range?
A1: The sensor uses an advanced coil design and proprietary calibration to maintain consistent linear output across the full measurement range.
Q2: Can this sensor operate reliably under high vibration conditions?
A2: Yes, the PROXPAC XL is specifically engineered to withstand harsh vibration environments without performance degradation.
Q3: How is the sensor connected to the monitoring system?
A3: It connects via a shielded extension cable to a Proximitor module, which conditions and transmits the signal to monitoring equipment.
Q4: What role does the Proximitor play in this system?
A4: The Proximitor supplies DC excitation to the probe, converts the return signal, and provides a linear voltage output proportional to displacement.
Q5: Is the sensor resistant to electromagnetic interference (EMI)?
A5: Yes, the probe and cables are shielded to reduce EMI and guarantee signal integrity in industrial environments.
Q6: Can it be used for both radial and axial measurements?
A6: Absolutely, the sensor is suitable for both radial shaft vibration and axial position monitoring applications.
Q7: What is the typical frequency response of this sensor?
A7: It offers a frequency response from DC up to 10 kHz, suitable for most machinery vibration monitoring.
Q8: Does the sensor require recalibration over time?
A8: Normally, recalibration is not required, thanks to its long-term stability and factory calibration.
Q9: How does the sensor behave in extreme temperature variations?
A9: The wide operating range (-35°C to +180°C) ensures stable performance even in fluctuating thermal conditions.
Q10: Is this sensor compatible with legacy Bently Nevada systems?
A10: Yes, it is backward compatible with many earlier Bently Nevada monitoring systems, provided the correct Proximitor and cabling are used.
