    • A silo rotary unloader monitor provides an indication of a rotational speed of the rotary collector ring of a material unloading device suspended within the top portion of a vertical silo. A limit switch has an actuating sensor biased into engagement with a sinusoidal cylindrical surface formed on a wheel mounted for rotation with the rotary collector ring. An electric circuit connected to the limit switch causes a remotely mounted electric signalling lamp or buzzer to flash or sound at a rate proportional to the rotary speed of the collector ring.
    • 筒仓旋转卸载器监视器提供悬挂在垂直仓的顶部内的卸料装置的旋转集合环的转速的指示。 限位开关具有致动传感器,该致动传感器被偏置成与安装成与旋转集电环旋转的轮上形成的正弦圆柱形表面接合。 连接到限位开关的电路导致远程安装的电信号灯或蜂鸣器以与收集环的旋转速度成比例的速率闪烁或发出声音。
