FLXA21两线制液体分析仪可以连接一台或两台传感器进行测量。分析仪采用模块化设计，使用不同的传感器模块，可实现以下四种测量目的: pH/ORP(氧化还原电位)、接触式电导率(SC)、感应式电导率(ISC)或溶解氧(DO)。
电导率仪具有温度补偿功能，内置标定用缓冲液表可以监视电池结垢，并提高电导率测量精度。通用性高，电池常数范围为0.005～50cm-1，而且，两电极和四电极传感器均可使用。此外，可以使用5种温度传感器，以实现精确温度补偿。
可为蒸汽、凝液和锅炉用水等脱盐水提供超纯水补偿。在制药行业的超纯水监视中，FLXA21可根据水质标准监视过程液体的水质，以符合USP(美国药典)<645>章的标准(参见USP 23中645)。
为了广泛应用于工业环境中，FLXA21电导率仪具有不同的的外壳可供选择: 塑料、不锈钢或带抗腐蚀涂层的不锈钢。
communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general
Line. The field controller supports various field buses such as PROFIBUS, which is the most widely used open field bus in the world
Line international standard, divided into FMS, DP and PA, DP communication rate can be as high as 12MB. Can (din/is011898 standard) bus
The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform
Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.
System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large
