The FLXA402 offers multiple connection possibilities, eliminating
the need for multiple analyzers and providing greater flexibility.
This four-wire analyzer includes a color HMI and an easy
touchscreen operation with a simple menu structure in 9 languages
for simple and efficient setup and configuration.
With its modular design, the FLXA402 analyzer offers a range of
measurement choices with the respective sensor module, including
pH/ORP, resistivity/conductivity (SC), inductive conductivity
(ISC), percent concentration, dissolved oxygen (DO), and 4-20mA
input. Dual sensor measurements offer additional functionalities,
such as a calculated data function that can be customized.

FLXA402 Features
Support of Up to Five Sensors
The FLXA402 can connect up to five sensors, realizing
interruption-free measurement even during maintenance. Multiple
sensor measurement offers additional functionalities including a
variety of calculated data as well as the option to program the
analyzer as a redundant system.
Advanced Functions
With the FLXA402, one analyzer can accept: pH/ORP, Contacting
Conductivity (SC), Inductive Conductivity (ISC), Dissolved Oxygen
(DO), and Optical Dissolved Oxygen Sensors with self-diagnostic
capabilities. Additional functions include:
- Continuous measurement of sensor impedance, asymmetric potential,
and slope, and continuous monitoring for electrode
contamination/damage, burnout, and a decline in measurement liquid
level (ex. pH Analyzer)
- Online Sensor Wellness checking for predictive maintenance
Expert Guide: 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 9 languages. The display of sensor
status and estimated maintenance time improve efficiency. The
interactive screen is housed in a robust aluminum die-cast housing.
Advanced Flexibility: 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. FLXA402 allows for the connection of up to five
possible sensors resulting in a reduction in CAPEX and OPEX.
Preparing for the Future
Industrial automation is moving toward SMART products, with sensors
changing from analog to digital SMART. This transition can affect
plant operations and take time to fully implement.
In addition to being a high performance standalone analyzer, the
FLXA402 is also a component of the new Yokogawa SENCOM 4.0
Platform, a SMART sensor system that simplifies in field
maintenance and calibration. With the SENCOM 4.0 Platform,
upgrading to the next generation SMART product is easy, and an
upgrade transfer can be done at any time with little impact on
operations.
Data Mobility
SD card or Ethernet for easy data transfer and remote service,
allowing for more in-depth process analysis.
