Measuring module KDM24
Measuring module KDM24 is a component of a measuring unit KDR and is designed to measure external source output voltage or ICP-sensor output voltage in one or several measuring channels. Maximum number of measuring channels if four.
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.
KDM24 technical specifications are proved by the Certificate of measuring device type approval RU.C.34.004.А № 52606, issued by the Federal technical regulation and metrology agency, Certificate of compliance № РОСС RU.ME79.H00188 and Declaration of conformity № ТС RU Д-RU.ME79.B.00027, registered by electric equipment certification body «Electroprivod», registration number РОСС.RU.0001.11ME79.
