通用型压力变送器
PE系列
原理,结构                                                                              
基于陶瓷电容技术,当加在陶瓷电容上的压力增大时,电容值增相应增大,电容值 正比于压力值。                                                                              
特点                                                                                   
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0.1、0.2、0.5,陶瓷测量界面抗腐蚀性好。齐平膜型可用于粘性介质。可在现场调节零点、满量程。带有LED显示。                                                                                  
应用                                                                                   
"气液两用型,可用于液压及气动系统。适用于以下行业:
钢铁行业/ 机械设备/ 空气压缩工业/ 制冷及空调/ 起重及传输系统"
