Rotas programmable rotational speed monitor

The Rheintacho rotas programmable rotary speed monitor is a pulse value system – its primary application is to monitor rotary speed and velocity based on period duration measurement. If the upper or lower thresholds are exceeded, it actuates relay outputs according to the set commands. There is also a version with a scalable current output for analog measured values.

The rotas rotational speed monitor not only stands out because of its wide range of freely programmable functions and fast, flexible signal processing; it is also very easy to use, is simply and compactly designed, and has only six controls.

The integrated LC display clearly shows measurement and status values, as well as dialogs for programming.

The rotas rotational speed monitor has a huge variety of applications. It monitors combustion engines in power plants and ships, as well as in gas, water and wind turbines, and can also be used for process monitoring in paper, foil or textile production. Drive units of machine tools and processing centers can also be excellently monitored with the rotas rotational speed monitor.

The rotas rotational speed monitor takes on an important role in complex systems. Working independently, it takes the load off the higher level control system. If problems occur, it triggers an alarm function via its relay outputs. In shipping applications, the rotas acts as a secondary safety circuit to shut down the engines in emergencies. The rotas is approved as an emergency stop system by Germanischer Lloyd (GL).
