The digital hand-tachometer rotaro Te is a device for measuring rotational speed and velocity, as well as length. The compact device has two measuring methods. One is optical, and therefore non-contacting; the other is mechanical using an adapter and various probes.
Using a special adapter, the rotaro Te can measure speed and length of ropes up to 8 mm diameter, e.g. in elevator applications.
Typical applications of the rotaro Te are service and maintenance work within the elevator systems.
