The Series PLS2 is an electromechanical level switch designed for level monitoring of bulk materials. The rotating measuring vane is driven by a brushless synchronous motor at one revolution per minute. As product builds up, the paddle rotation is impeded and the resulting motor torque activates the output switch and stops the motor. A spring mechanism reactivates the motor and returns the switch to normal state when the material no longer impedes the paddle rotation. A torque adjusting mechanism eliminates the need for different sized paddles. The PLS2 is designed with the industry standard 1-1/4" male NPT connection and unit can be side or top mounted.

PLS系列 旋叶式料位开关 采用磁力驱动，这个传承了亿万28 的Mark系列阀位指示系列产品几十年的制造经验。每分钟一转转速的电机采用磁力驱动旋叶。当物料料位升高阻挡旋叶而产生的力矩使得开关动作，并切断电机电源。当物料料位下降，不阻挡旋叶，弹簧的回力使得开关回位，电机也开始带动旋叶旋转。标准配置是全天候防护，可选防爆型的，它可侧面安装或顶部安装。PLS型料位开关的工艺连接采用工业标准的1-1/4" NPT 外螺纹连接，可选法兰连接方式。

DBLM系列 小型旋叶式料位开关可靠耐用，用于干物料的料位监测，特别适用于安装空间受到限制的场合，这款小型的料位开关监测物料的高，中和低位，避免溢出，堵塞或空罐等。它以每分钟一转的速度由电机带动四个塑料叶片旋转，当物料阻止它旋转时，它切断电机电源，触发开关动作。DBLM可选择1-1/4" 到 3/4"异径接头来取代标准的接头。
