Core High-Frequency Displacement Measurement
The EPRO PR6424/000-030 CON021 is a high-performance eddy current proximity transducer system. This non-contact system measures dynamic displacement and vibration on ferromagnetic steel targets. It delivers a sensitivity of 4 V/mm for precise gap measurement with minimal long-term drift. Consequently, it is essential for monitoring shaft vibration, axial position, and eccentricity in high-speed turbomachinery.
Exceptional Dynamic Performance and Range
This system offers a wide dynamic frequency range from 0 to 20,000 Hz (-3dB) for capturing both slow trends and rapid vibrations. It features a fast rise time of less than 15 microseconds for accurate transient detection. The PR6424/000-030 CON021 provides a nominal air gap of approximately 2.7 mm for optimal sensor installation. Furthermore, its linearity error is within ±1.8% for reliable and repeatable measurements.
