Measuring module KDM25

Measuring module KDM25

Measuring module KDM25

Measuring module KDM25 is a component of a measuring unit KDR and is designed to measure output voltage of ICP-sensor in one or several measuring valves. Maximum number of measuring channels – eight.

The module serves for applications which require high quality of digitalization of variable signal with high spectral accuracy of transformation, wide dynamic range and high signal-to-noise ratio. Four module channels are strictly parallel, independent, with no commutation delay between each other.

The module can detect short-circuit failures and one-phase open fault of ICP-sensors directly during the measurement process. Eight channels of AD converter are strictly parallel, independent, with no commutation delay between each other
