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.
About OpreX
OpreX is the comprehensive brand for Yokogawa’s industrial
automation (IA) and control business and stands for excellence in
the related technology and solutions. It consists of categories and
families under each category. This product belongs to the OpreX
Analyzers family that is aligned under the OpreX Measurement
category.
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).
