Product Description
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, including frequencies in general and rotational speeds in special cases. The input signals are evaluated using the cycle method, measuring the period of oscillation and converting it into frequency or rotational speed via a fast controller.
