艾默生公司 (Emerson) 提供的独家技术,可以绝对保证在 2 秒钟内完成仪表结构完整性和测量性能校验(从电子部件到传感器)的唯一诊断工具。
高准智能仪表自校验的优点
降低成本
• 不需要劳务、外包标定服务,不会造成生产中断和潜在损坏,因而可节省数千元成本
• 可延长花费昂贵的检验和标定周期增加正常运行时间
• 无需将仪表从生产线上拆下或者中断生产流程来测试仪表结构完整性
• 针对故障排除做出迅速反馈,以便查出仪表性能问题,并专注于过程动态排除不确定性
• 根据需要或按照预定的进度运行智能仪表自校验功能,持续地保证了关键流量点测量健康状态和稳定性
• 可及时查取仪表健康状态校验结果,以便发出问题预警
• 利用艾默生的智能无线技术访问停滞的诊断或校验难以触及之设备的性能
提高质量和安全性
• 对照出厂规格测试仪表,确保最佳性能以及最佳的合规生产
• 针对每台仪表建立备有存储结果的审计追踪,实现数据易捕获并可以进行可视分析和报告
• 避免无必要的亲赴现场及测试程序,不破坏过程密闭性
