P+F Rotation Speed Monitor KFU8-DW-1.D

The KFU8-DW-1.D Speed Monitor is a device for the indication and monitoring of periodic signals, which occur in almost all areas of automation and process technology, i. e. of frequencies in general and rotational speeds in special cases. The input signals are evaluated in accordance with the cycle method, i. e. by measurement of the period of oscillation and conversion into frequency or rotational speed by a very fast controller.
