1.General Introduction
Yokogawa FLXA402 pH analyzer is a 4 wire modular-designed converter which accepts 5 sensors measurement, accept both traditional analog and SENCOM 4.0 digital Smart sensors. It offers a wide range of measurement as: pH/ORP, Contacting Conductivity (SC), Inductive Conductivity (ISC), Dissolved Oxygen (DO), and Optical Dissolved Oxygen Sensors with self-diagnostic capabilities. A color Human Machine Interface (HMI) offers easy touch screen operation and simple instinctive menu structure in 9languages. Menus of display, execution and setting are displayed in a selected language. Start up and commission time is minimal with the quick startup menu for immediate measurement. Variety of communications are available, mA/HART, Modbus TCP, Modbus RTU/RS485. And FieldMate working on tablet PC can be used as a local display via Bluetooth or RS485.
