Speed monitors – safe and convenient standstill and speed monitoring, optionally also without sensors – SAFEMASTER S
The SAFEMASTER S series standstill and speed monitors are used for safe standstill and speed monitoring of drives. The speed monitors detect and signal the standstill and speed of machines and systems in automatic as well as in setup mode. Dold offers efficient and economical solutions for safe sensorless speed monitoring, sensorless frequency monitoring as well as drive monitoring via proximity switches. The standstill and speed monitor is used in machines and systems where machine movements or moving parts can pose a risk to man and machine. For example, safe monitoring of the reduced operating speed in setup mode increases the safety of the operating personnel. It also increases productivity by preventing unnecessary shutdowns.
