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 eight languages*. Sensor status and estimated maintenance time notification improve efficiency. The interactive screen is housed in a robust aluminum die-cast housing.
*8 languages: English, Chinese, Korean, German, French, Spanish, Portuguese, Japanese
Advanced Flexibility: Modular Design for Increased Scalability
The FLEXA™ series analyzer features a modular design with replaceable sensor modules, enabling the construction of various of systems. FLXA402T allows for the connection of up to two 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 implement fully.
In addition to being a high-performance standalone analyzer, the FLXA402T is also a component of the Yokogawa SENCOM4.0 Platform, SMART sensor systems give you more insight because they possess in-depth knowledge of their health status for predictive asset management and sensor condition to ease troubleshooting.
With the SENCOM4.0 Platform, upgrading to the next generation SMART product is easy and can be done at any time with little impact on operations.
SD card or Ethernet for easy data transfer and remote service, allowing for more in-depth process analysis.
Turbidity and Chlorine 2 in 1 system configuration
The first module can be connected the Chlorine sensor unit or the Turbidity detector unit, and the second module can be connected the Chlorine sensor unit, Turbidity detector unit , pH sensor or conductivity sensor. For example, Chlorine sensor unit and Turbidity detector unit can be controled by one Liquid Analyzer.
