Multi Channel 4-Wire Analyzer FLXA402 with 110VAC 24VD Power Supply 4-20mA HART Modbus Bluetooth Communication and 4 SPDT Relays

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.

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.

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.

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

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.

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.

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.

SD card or Ethernet for easy data transfer and remote service, allowing for more in-depth process analysis.
