Multifunctional displays from motrona are used in automation and mechanical engineering in order to visualize, record, calculate or control frequencies, times and (in the case of dual-channel devices) sums, differences or ratios. This results in applications such as tachometer, speed meter, sum-, difference- or ratio-display, baking time display, industrial stopwatch or counter. With our digital frequency meters, we offer the right device for almost every industrial machine requirement. The devices process the signals of conventional incremental rotary encoders, sensors, light barriers, proximity switches or length measuring systems.
