Explanation/Annotation:For operational industrial control of strength and homogeneity of concrete and solution by the method of impact impulse according to the state standard 22690.
Detailed model description:In contrast to analogues, the device is provided by:
- input unit of hit rate of key word;
- marking device of measurements by the type controlled product; - calculation function of concrete class with option of coefficient of variation;
- exception function of erroneous intermediate value.
the device has the non-volatile memory, the data mode on computer through ÑÎÌ-ïîðò and are provided by input unit in programmer of individual calibrating characteristics.
the processing algorithm of measuring results includes:
- averaging of intermediate values;
- comparison of each intermediate value with middle, followed by rejection Significances, having the abmodalities, more than permissible;
- averaging left after rejection of intermediate values; - indication and record in mind of finite value of strength and class of concrete.
