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                                                                                  技术参数                                                                                   ●压力：                            20bar                                                       ●介质温度：                            130℃                                                      ●介质密度：                            ≥0.75g/cm3                                                   ●输出                                                                                 开关量输出型:      触点类型:    干簧管开关                                                                         触点容量:    250VAC, 0.5A                                                                                    输出:        常开/常闭 可选                                                     模拟量输出型:      供电:        24±5%DC                                                                   输出:        4…20mA                                                                                    负载:        ≤750Ω                                                  ●防护等级：       IP65                                                        ●接线方式:          端子接线                                                        ●材料:                 不锈钢                                                     ●过程连接:          螺纹连接G2                                                                               法兰连接DN50     开关输出型产品多可带浮球数
