ED Series Speed Monitor

The SRS/SRT/ED belt conveyor safety products use various electromechanical and electronic technology to protect equipment and personnel.  These safety devices include:

– SRT belt misalignment switch
– SRS safety stop switch
– ED series speed monitor


The SRS/SRT/ED belt conveyor safety products work to ensure and protect equipment and personnel. The ED series is another of the Aplus Finetek belt conveyor safety products. The ED is a speed monitoring safety instrument for use in monitoring the speed of rotating devices such as rotating conveyor shafts, motor shafts, etc. The ED speed monitor will measure RPM from 1~999rpm and indicates speed on its internal display. The primary output is a 4-20mA analog signal of the measured speed that can be tied into a PLC or DCS or panel meter. An alarm relay output is also provided.
