◆ 可对由NO、SO2、CO2、CO、CH4 中的4 种成分以及包括O2 在内最多5 种成分的气体浓度同时进行连续测定。
◆ 通过采用高灵敏度、高可靠性的质量流式双检测器，可以几乎不受其他气体的干扰成分的影响，稳定性优秀。
◆ 通过采用大型LCD 显示屏，所有测定成分的显示和计算值的显示易于识别，对话形式的操作，测定操作简单容易。
◆ 实现最大量程比1:25。并且还可在指定量程范围内自由地设定、变更量程。
process control station
The i/0 protection unit of the PS is used to receive process signals from the rack mounted i/0 modules supported by the PS. Each field controller PS can only be configured
-Block fi810f card. — The two fi810f interface cards on the redundant PS. can be switched redundantly.
S800 and S900 are distributed i/0 for process control stations. They communicate with their controllers through Prof ibusdp Fieldbus
Communication, which can be installed in the controland PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer platform.
