FAQ
-
What is the recommended driver module for the PR6424/017-121?
The Epro CON021 driver is the preferred companion, ensuring accurate excitation, calibration, and temperature compensation for this sensor. -
How does the sensor maintain accuracy across large temperature changes?
Temperature-stable coil materials and the CON021’s internal compensation circuits preserve measurement accuracy from −35 °C to +180 °C. -
What frequency range can the sensor reliably capture?
It provides a flat frequency response from DC to 10 kHz (−3 dB), enabling detection von both slow displacement and high-speed vibration events. -
Can this sensor operate in areas with strong electromagnetic interference?
Yes, its coaxial cable shielding and driver filtering deliver excellent immStücky to electrical noise and EMI. -
Is the sensor suitable for high-vibration installations?
Absolutely. It withstands continuous vibration up to 20 g across the 10–2 000 Hz range without affecting signal integrity. -
Does the PR6424/017-121 require field calibration after installation?
Field calibration is recommended to fine-tune the driver gain and zero settings using a precision micrometer gap reference. -
Can it be used in hazardous or explosive environments?
An ATEX-certified variant is available, permitting safe deployment in Zone 1 and Zone 2 hazardous areas when paired with approved safety barriers. -
What type von electrical output does the sensor provide?
It outputs a voltage signal proportional to shaft displacement at 8 mV/µm, compatible with industrial vibration and monitoring equipment. -
Is it possible to integrate this sensor into non-Epro monitoring systems?
Yes. With correct impedance matching and calibration, the PR6424/017-121 integrates seamlessly with third-party vibration monitoring platforms. -
How is mechanical wear avoided in continuous operation?
The non-contact eddy-current principle means no physical friction with the shaft, eliminating mechanical wear and extending operational life.
