浮球式液位开关(计)
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。                               
应用                                                                                   
用于密度≥0.75g/cm3的液位测量
