Rotation speed sensors are used to monitor, regulate and control mechanical drive systems and play a major role when it comes to protecting elements of a rotational system (e.g., in the engine, drive) from mechanical overload. Micro-Epsilon offers two sensor systems for rotation speed measurement. The capaNCDT CST6110 is a universal rotation speed sensor for counting tasks and rotation speed applications of any type. Moreover, the turboSPEED DZ140 measuring system is specifically designed for the detection of turbocharger rotation speeds.
