采用氧化锆传感器，使用寿命长，性能稳定传感器更换简单
●使用YOKOGAWA独特的技术一分子连接法安装铂电极，防止铂金属与氧化锆元件分离。
●无线电极设计，避免断线故障。
●特殊涂层保护铂金属，防止传感器老化或受损。
●无需特殊工具，只需拆下探头顶端的4颗螺钉，便可取出锆池。
放入新锆池重新组装只需10分钟。更换锆池后，仅需进行一次普通的零点量程校正即可。
unified global database is used for the entire control system, thereby reducing
cost and time investment in establishing data communication and interactive access.
And ensure the consistency of data throughout the system.
●Provide system-wide unified inspection of user applications, overriding
from process control stations, operator stations to intelligent field devices, including
Including the integrity and consistency check of the user program.
●The programming language strictly complies with the international standard of IEC61131-3, and has
There are high-performance graphics editing functions:
– Function Block Diagram (FBD)
-Ladder Diagram (LD)
– Instruction List (IL)
– Sequence Control Chart (SFC)
. Structured Text (ST)
●Extensive function block library, user-defined function blocks can also be added
Added to it, the macro library and graphic symbols can be customized for the user.
Blocks can create graphics and operator panels.
●Any standard can be integrated by means of GSD file import
PROFIBUS-DP and PA devices, and through user-defined pairing
dialog box to design the configuration window for these devices.
●Profibus field controller can be integrated through FDT/DTM technology

system structure
The Freelance 800F process control system is divided into operator levels
and process control level. The operator level contains controls for operation and display.
Archiving and logging, trending and alarming functions. Controller executes open loop
and closed loop control function.
