2-Wire Dual Channel Transmitter/Analyzer Yokogawa FLXA202
The FLEXA™ series analyzers are modular-designed analyzers used for continuous online measurements in industrial installations. They offer single or dual sensor measurement, making them the most flexible 2-wire analyzer available.
With the FLXA202, there is no need for multiple analyzers, since it is easily scalable at the site location by swapping the internal measurement module to what is needed, giving you more flexibility and optimizing your OPEX.
Main Features
Support of Up to Two Sensors
Through the installation of up to two sensors, FLXA202 realizes interruption-free measurement even during maintenance. For dual sensor measurement, the sensor modules must be the same parameter – pH/ORP and pH/ORP, SC and SC, and DO and DO. Dual sensor measurement offers additional functionalities including a variety of calculated data from the two measuring parameters, as well as, the option to program the analyzer as a redundant system.
Advanced Functions
With the FLXA202, one analyzer can accept any of four types of measurements: pH/ORP, Contacting Conductivity (SC), Inductive Conductivity (ISC) and Dissolved Oxygen (DO)Sensors with self-diagnostics capabilities. Additional functions include:
- Continuous measurement of sensor impedance, asymmetric potential, and slope, and continuous monitoring for electrode contamination/damage, burnout, and decline in measurement liquid level (ex. pH Analyzer).
- Online Sensor Wellness checking for predictive maintenance.
Clear Touch Panel Display for Improved Operability
The FLEXA™ series analyzer provides improved operability with intuitive touchscreen operation, featuring a clear display and user-friendly indication with 12 languages. A quick setup menu for immediate measurement and a display of sensor status and estimated maintenance time improve efficiency. The interactive screen is housed in a robust aluminum die-cast housing (FLXA202).
Modular Design for Increased Scalability
The FLEXA™ series analyzer features a modular design with replaceable sensor modules, enabling the construction of a variety of systems. Users can opt to do without a display and can also select the case material (plastic or stainless steel).

Benefits of Conductivity / Resistivity Measurement
Realizes highly versatile and high-precision measurement
- The built-in temperature compensation function and calibration standard table enable higher-precision conductivity measurement by monitoring the contamination of the cell.
- Cell constants correspond to 0.005 to 50 cm-1.
- Both 2-electrode and 4-electrode sensors can be used.
- Five types of temperature detectors are supported, and accurate temperature compensation (linear temperature compensation/matrix temperature compensation) is performed.
Pure water and compliance with stringent standards for WFI monitoring (USP item <645>)
- In the analysis of demineralized water, steam, condensate, and boiler water, pure water compensation is performed.
- Monitors the quality of the process solution in accordance with the USP (U.S. PHARMACEUTICAL) entry <645> (see Section 645 of USP23) guideline (U.S. PHARMACEUTICAL GUIDE), which serves as the basis for monitoring pure water in the PHARMACEUTICAL INDUSTRY.
Compatible with various other types of explosion-proof
