Dwyer 102/1102系列法兰箱式液位控制
Dwyer 102/1102系列法兰箱式液位控制
该系列102&1102法兰室式液位控制器是外部保持架式电平开关，其自包含在侧安装体中。坚固的102系列工作在压力400 psi(28 Bar)和温度至425°F(218°C)。102系列的最低比重为0.60。在相同的工作压力和温度下，1102系列的比重为0.40。102和1102系列包含不锈钢浮子，并提供铸铁，铸钢，或廉价铸造316 SS浮标室的选择。这些系列非常适合于压力容器或真空容器容易获得的应用。使用密封快速动作或水银触点的电路可在各种动作中使用，包括SPST、SPDT、DPDT和DPST组合。可选电路适用于低电流、低电压直流电、高直流电或高温应用。电气外壳提供一般用途；耐候、防爆或防爆/防蒸汽能力。102的设计还包括三个1"NPT工艺连接侧/侧或侧/底部管道。当使用侧/侧工艺连接时，底部1"NPT连接可用作排水。
独特的设计允许简单地从检查板上拆下四个螺栓，以检查浮子和气室的清洁或磨损，而不断开管道或电路。
电气外壳提供一般用途、耐候性、防爆或防爆/防蒸汽能力，以及成本效益高的铸316 ss浮子室选项。
使用密封快速动作或水银触点的电路可在各种动作中使用，包括spst、spdt、dpdt和dpst组合。
102的设计特点是三条1英寸的NPT工艺连接，用于侧/侧或侧/底管道，允许底部1“npt连接在使用侧/侧工艺连接时用作排水。
