HART协议技术极大地提高了仪表日常维护效率。HART(Highway Addressable Remote Transducer),可寻址远程传感器高速通道的开放通信协议,是美国ROSEMOUNT公司于1985年推出的一种用于现场智能仪表和控制室设备之间的通信协议。HART装置提供具有相对低的宽带,适度响应时间的通信,经过30年的发展,HART技术在国外已经十分成熟,并已成为全球智能仪表的工业标准。任何先进的技术遇上特殊
HART protocol technology greatly improves the routine maintenance efficiency of the instrument. HART (Highway Addressable Remote Transducer), an open communication protocol for addressable remote sensor high-speed channel, is a communication protocol used by the ROSEMOUNT company in the United States in 1985 for field intelligent instruments and control room equipment. HART devices provide communications with relatively low bandwidth and modest response times. After 30 years of development, HART technology has matured abroad and has become the industry standard for smart meters worldwide. Any advanced technology in the special encounter
