The preset speed monitors | |
The electronic speed switches monitor the factory-set speed with high switching accuracy, including low operating speeds. Alternatively, they can be used as standstill monitors. As a consequence, the speed switches play their part in system and personnel protection. They are installed on motors, for example in cranes, in mining operations as well as in rolling mills and more. |
