OX400低浓度氧化锆氧分析仪精度高，可靠性高，测量量程范围大，可测量从O~10ppm至O~100vol%的氧气浓度。氧分析仪OX400是横河电机在该应用领域的长期经验积累和优秀业绩基础上研发出来的最新机型。
氧化锆传感器采用了新型薄膜沉积专利技术，在氧化锆元素和铂层间建立了分子键连接。这样不仅预防剥离，还可以减小传感器尺寸，确保快速响应和超长寿命。
hrough the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple engineering: configuration, commissioning and diagnostics using only the same tool CBF (Control Build F) software
