法兰式静压液位变送器
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。
