What is a Broken Chain Protector?
The Broken Chain Protector (DK-SCD Series) is an industrial safety device designed to monitor chain operation in conveyors, elevators, and material handling equipment. It detects abnormal chain speed, breakage, and slippage in real time, triggering an immediate alarm or emergency stop to prevent equipment damage and production downtime.
Drksir’s DK-SCD series broken chain protectors integrate speed detection and relay output technologies, delivering stable and reliable protection in heavy-duty industrial environments.
