技术规格

Applications

• Turbomachinery Vibration Monitoring: Continuous measurement of shaft vibration amplitude and position for turbines, compressors, and generators.

• Bearing Gap Detection: Detects shaft displacement relative to bearing housings for predictive maintenance.

• Pump and Motor Monitoring: Provides real-time data to prevent cavitation damage or misalignment failures.

• Rotating Equipment Diagnostics: Integrates with Epro CON021 or compatible drivers to feed vibration and displacement data to plant control systems.

• Condition-Based Maintenance: Supports data acquisition for advanced predictive maintenance programs in refineries, petrochemical plants, and power stations.

Advantages

• High Measurement Accuracy: 8 mV/µm sensitivity with minimal drift ensures precise shaft-position data.

• Wide Temperature Capability: Operates reliably in environments up to +180 °C, making it suitable for hot machine zones.

• Rugged Construction: Stainless-steel IP67 housing and PTFE-insulated cable provide excellent chemical and moisture resistance.

• Easy Integration: Seamlessly connects to Epro CON021 drivers and most industrial monitoring systems.

• Fast Dynamic Response: DC to 10 kHz frequency range captures rapid shaft motion and transient events.

• Low Maintenance: Non-contact design eliminates wear and extends service intervals.

FAQ

1. What is the typical linear measuring range of the PR6424/018-000 sensor?
   The sensor provides a linear range of approximately ±2 mm around its calibrated mid-gap, suitable for most standard shaft-vibration monitoring applications.

2. Which driver module is recommended for optimal performance with this sensor?
   Epro recommends pairing the PR6424/018-000 with the CON021 driver, which provides proper excitation, signal conditioning, and calibration support.

3. How is temperature compensation achieved within the sensor system?
   The sensor incorporates a temperature-stable coil and uses the CON021 driver’s compensation circuitry to maintain accuracy across the full –35 °C to +180 °C range.

4. What type of cable is supplied and how can it be extended?
   The sensor comes with a factory-installed PTFE-insulated coaxial cable. Extensions must use low-loss coax with compatible impedance to maintain calibration accuracy.

5. What is the maximum vibration level the sensor can withstand?
   It is rated for continuous vibration up to 20 g within a 10–2 000 Hz bandwidth without affecting measurement precision.

6. Is the sensor suitable for use in hazardous or explosive areas?
   Yes, an ATEX-certified version is available for installation in Zone 1 and Zone 2 hazardous environments when used with approved barriers.

7. How is the sensor calibrated in the field?
   Field calibration is performed by adjusting the CON021 driver’s zero and gain settings using a precision micrometer gap reference.

8. What is the typical frequency response and why is it important?
   The PR6424/018-000 supports a DC to 10 kHz frequency range, allowing accurate capture of both static shaft position and high-frequency vibration components.

9. Does the sensor require an external power supply?
   Power is supplied through the compatible driver module (±15 VDC), eliminating the need for a separate dedicated supply at the sensor location.

10. Can the sensor be used with non-Epro monitoring systems?
    Yes, provided the monitoring system matches the sensor’s impedance and excitation requirements; proper calibration is essential to maintain accuracy.
