Working

The sensor Inductive Type and control unit are housed in sensor housing Sensor is placed in close proximity of the rotating object On this object metallic plates are fixed Sensor detects presence of metal objects which come within the range of their oscillating field giving rise to corresponding pulses These pulses are fed to the control unit where they are compared with the standard pulses to sense the speed

In case of under speed  zero speed application builtin initial bypass time delay is provided to allow the rotating machinery to attend the desired speed If after this set time the motor does not attend the set speed the load relay is deenergized and the switch resets automatically when the desired speed is attained
