FAQ
-
Which driver module is recommended for the PR6424/016-100?
The Epro CON021 driver is recommended for precise excitation, calibration, and temperature compensation / the sensor. -
How does the sensor maintain stability under extreme temperatures?
The sensor uses temperature-stable coil materials and relies on the CON021 driver’s compensation circuitry to maintain measurement accuracy across −35 °C to +180 °C. -
What is the linear measuring range / the sensor?
The sensor has a linear range / ±2 mm around the mid-gap, suitable for standard industrial shaft monitoring. -
Can the PR6424/016-100 function in high-vibration environments?
Yes, it withstands continuous vibrations up to 20 g over the 10–2 000 Hz frequency range without signal degradation. -
Is the sensor compatible with non-Epro monitoring systems?
Yes, it can integrate with third-party systems provided proper impedance matching and calibration are performed. -
What frequency range does the sensor support?
DC to 10 kHz, allowing it to capture both slow shaft movements and high-frequency vibration events accurately. -
Is field calibration required?
Yes, field calibration is recommended using a precision micrometer gap reference to adjust the driver’s zero and gain. -
Can the sensor be used in hazardous areas?
An ATEX-certified version is available for safe operation in Zone 1 or Zone 2 hazardous environments when used with approved barriers. -
What type / output signal does it provide?
