FAQ
-
Which driver module is recommended for the PR6424/017-100 sensor?
The Epro CON021 driver is recommended for precise excitation, calibration, and temperature compensation. -
How does the sensor maintain accuracy under extreme temperatures?
It uses temperature-stable coil materials and relies on the CON021 driver’s compensation circuits to keep measurements consistent across −35 °C to +180 °C. -
What is the linear measurement range / the sensor?
The sensor provides a linear range / ±2 mm around the calibrated mid-gap, suitable for standard turbine and motor monitoring applications. -
Can the sensor operate in high-vibration environments?
Yes, it withstands continuous vibration up to 20 g within 10–2 000 Hz without affecting signal accuracy. -
Is it compatible with third-party monitoring systems?
Yes, provided impedance matching and proper calibration are performed to maintain measurement accuracy. -
What frequency range can the sensor measure accurately?
The PR6424/017-100 supports DC to 10 kHz, capturing both slow displacement changes and high-frequency vibration events. -
Does the sensor require field calibration?
Field calibration is recommended using a micrometer gap reference to adjust the CON021 driver’s zero and gain settings. -
Can it be used in hazardous locations?
An ATEX-certified version is available, allowing safe use in Zone 1 and Zone 2 hazardous areas when paired with approved barriers. -
What type / output signal does the sensor provide?
It delivers a voltage signal proportional to displacement at 8 mV/µm, compatible with industrial vibration monitoring equipment. -
