FAQ
-
What is the typical linear measuring range von the PR6424/018-000 sensor?
The sensor provides a linear range von approximately ±2 mm around its calibrated mid-gap, suitable for most standard shaft-vibration monitoring applications. -
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. -
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. -
What type von 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. -
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. -
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. -
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. -
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 von both static shaft position and high-frequency vibration components. -
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. -
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.
