Yokogawa FLXA202-D-B-D-AD-C5-C1-A-N-LA-N-NN FLXA202 2-Wire Analyzer
General of Yokogawa FLXA202-D-B-D-AD-C5-C1-A-N-LA-N-NN FLXA202 2-Wire Analyzer
The model FLXA21,FLXA202 2-Wire Analyzer, one model of FLEXA® series, offers single or dual sensor measurement. The modular-designed analyzer offers 4 kinds of measurements – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.
For dual sensor measurement, the combination of two same type sensor inputs – pH/ORP and pH/ORP (analog sensor only), SC and SC, and DO and DO –are available with two sensor modules. Dual sensor measurement offers additional functionalities; calculated
data function and redundant system.
Variety of calculated data from two measuring parameters is selectable for each measurement.On the redundant system built on two measuring parameters of two sensor inputs, main output parameter is automatically switched over to the second sensor output in case of the main sensor’s failure condition.
Addition to conventional analog pH/ORP sensors, the analyzer FLXA21 can be connected to Yokogawa’s digital sensor, FU20F pH/ORP SENCOM® Sensor.
In the FLXA21 Human Machine Interface (HMI),2-wire type analyzer FLXA21 offers easy touch screen operation and simple menu structure in 12 languages.Menus of display, execution and setting are displayed in a selected language.

The analyzer FLXA21 automatically recognizes the installed sensor module and prepares the necessary menus for right configuration, even for dual sensor measurement.
For immediate measurement, the FLXA21 offers quick setup functionality. The quick setup screen appears when the analyzer is powered. Only a few setups –date/time, language, basic sensor configurations and output – will start the measurement.
The FLXA21 offers the best accuracy in measurement with temperature compensation functionality and calibration functionality. Sensor diagnostics and sensor wellness indication make measurement reliable.Logbook of events and diagnostic data is a useful information source for maintenance.
For hazardous location, the FLXA21 has approvals of ATEX, IECEx, FM, CSA, NEPSI and KOSHA.
Features of Yokogawa FLXA202-D-B-D-AD-C5-C1-A-N-LA-N-NN FLXA202 2-Wire Analyzer
Flexibility, reliability, low maintenance and low installation costs are among the benefits of theFLXA21 pH/ORP analyzer. Designed to meet the exacting requirements of measuring pH and ORP in the modern industrial environment, it contains many features to ensure peak precision whatever the application.
This 2-wire (loop powered) analyzer is housed in a robust IP66/NEMA 4A field mountable case. The need for expensive cabling is minimized. Sensor diagnostics is enhanced by an improved impedance check, and the addition of a logbook feature. Calibration history is available in the display, and full logbook data is accessible through the HART bi-directional communication link, and is used to store important configuration, calibration and diagnostic data. Prediction of sensor failure is possible by reference to the logbook.
Microprocessor-aided calibration uses internal buffer tables and stability checking to ensure maximum accuracy with minimum effort. Process temperature compensation enhances accuracy in applications where the influence of temperature is seen in process pH changes. pH and ORP or rH measurements can be made simultaneously when an appropriate sensor combination is used.
Yokogawa has implemented three leading process Fieldbus technologies in their FLXA21 series: HART, Foundation Fieldbus H1 and Profibus PA. All transmitters are provided with the important and widely used Device Description files that provide information on parameters and other data in each device, as well as the ability to include algorithmic relationships such as calibrations.
