4-channel vibration measurement and analysis module 24-bit resolution at 51.562 kHz IEPE supply Internal calculation of an extensive range of condition parameters Data buffer upload This compact module provides a system for measuring and analyzing vibrations for use in applications such as condition monitoring for machinery and equipment. The measurement unit consists of 4 vibration inputs with 24-bit converter resolution and a sampling frequency of 51.562 kHz. Each of the inputs has a separately activated constant current source to supply IEPE sensors. Signal conditioning algorithms integrated in the module include configurable high and low-pass filters, an envelope curve generator and a Fourier transform, among many others. Various characteristic values and configurable frequency bands are available to ensure seamless signal evaluation. The module-internal calculation minimizes the load on the bus and PLC. Whether used for traditional condition monitoring or as a means of process optimization, the maximum evaluable frequency of 10 kHz and maximum frequency resolution of under 63 mHz make it suitable for almost any application. If desired, it can also be used as a standard input module. The ability to upload all values in the time and frequency domain also allow measurements to be evaluated externally or archived.
