EXAxt 450系列专用于由微型计算机(PDA)支持的、Yokogawa EXA系列简单易用的优秀功能组合。
PH450将pH测量与先进的温度补偿功能和预先加载的校正标准以及稳定性检查组合，为工业领域提供最佳精度。
PH450是真正的多变量分析仪，它将pH测量与温度和ORP（氧化还原）测量组合，且所有这些测量可通过不同的输出功能进行利用：两路mA输出电流、四个独立的SPDT触点输出和HART。DD和DTM文件都能通过HART手持终端、HIM监视器和Pactware PC配置器直接连接。
EXAxt PH450提供mA输出或触点输出上PID控制的所有功能并带整体清洗功能。
电化学分析仪最重要的是可靠性和重复性。这在PH450中对pH和参比电极的传感器阻抗监测中得到保证。另外，该动态传感器检测与清洗循环功能结合，确保在最小维护情况下的无故障和精确分析。
EXAxt 450真正独特之处是其人机界面。高分辨率图像显示和触摸屏操作，使操作者可以看见所有信息。触摸屏的配置就像操作PDA一样简单。语言选择简单及屏幕使用指南，确保获得现场应用最佳配置。
Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
