Product Description

SMARTsaa Zero Speed Switch with Digital Display to monitor speed of conveyers, crushers, rolling mills, agitators, mixers, stirrers, screw conveyers, bucket elevators and other industrial machinery. The digital display indicates equipment speed as well as set speed accurately. The device also actuates relay contacts at preset speed. Using these contacts, desired control action such as zero speed protection / under speed protection / over speed protection can be achieved. SMARTsaa SZZZ can also be used to indicate linear speed of equipment in MPM / MPH by suitable entry of scaling factor. Scaling factor is also adjustable.

Speed 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. Output is in the form of relay contact.

In case of under speed – zero speed application built-in initial by-pass 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 relay is de-energized and the switch resets automatically when the desired speed is attained.

Digital display models provide more features like field adjustable scaling factor, keypad setting, two point contact operation and Universal Speed Range etc.
