This contact is connected with the reverse coil in series, but it cannot energize so. By monitoring the motion of rotating.
Speed sensors and zero speed switches are used to protect equipment, processes, and people One of the simplest yet most effective devices for preventing such accidents is the zero speed switch (zss) When the speed sensor or speed switch detects a change in speed, a signal is sent to a control.
Working Principle of Zero Speed Switch
The primary function of a zero speed switch is to detect when equipment speed falls below a predetermined value or stops completely
When this condition occurs, the switch activates an alarm,.
