Mercoid浮筒液位开关205系列使用寿命长，运行可靠是205系列的固有特点

仲博平台官网产品信息

仲博平台官网 使用寿命长，运行可靠是205系列的固有特点。重型焊接碳钢室提供了一个操作高达1250 psi (86 bar)和工艺温度高达650°F(343°C)、400°F(205°C)的电气头总成控制。外部磁铁的使用减少了磁粒子在电枢管内积聚的可能性，以及随后的操作损失，因为可能会发生与内部磁铁斥力设计。结构的选择提供了适用于低比重(0.75)的设备。电气要求是通过使用密封的快速动作或水银开关在各种行动，包括SPST, SPDT, DPDT和DPST安排。可选电路可用于低电流/电压直流; 大电流直流; 或高温应用。检查当前图表中您的应用的开关。标准工艺连接是组合1“NPT和1”承插焊接轮毂。可选择法兰连接
