浮球式液位开关（计）
               IP65
                                          LV30系列

                                              原理，结构
                                              LV30系列产品分为模拟输出型和开关量输出型两种。
                                              模拟量输出型：磁性浮球随液位的变化不断触发检测杆中的磁簧开关,使得
                                              传感器的总电阻发生变化，该信号被变送器转换成标准4…20mA信号输出
                                              。
                                              开关量量输出型：液位上升或下降时，带动不锈钢磁性浮球上下移动,浮球
                                              触发检测杆中的的磁簧开关，发出信号。

                                              特点
                                              价格低廉，寿命长，可用于对液位的限位监控或连续监控。开关量型可提
                                              供多球多点监控，模拟量型可与监控仪表配合使用，实现上下限报警或连
                                              续控制。
