法兰式静压液位变送器
               IP65
                                            LV70系列

                                               原理，结构
                                               基于陶瓷电容技术，当液位增加时，加在陶瓷电容上的压力增大，使得电
                                               容值增大，电容值 正比于液位高低。

                                               特点
                                               法兰式安装，过载能力强，稳定性好，每年优于0.1%的满量程，抗干扰能
                                               力强，极高的精度及重复性,可达0.2、0.5级 ，可在现场调节零点、满量程
                                               。陶瓷测量界面抗腐蚀性好。

                                               应用
                                               适用于粘稠和浆状介质、强腐蚀液体、富含颗粒类介质，不易堵塞。
