Model FLXA212-Wire Analyzer
GS 12A01A02-01E
n GeneralThe model FLXA®21 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 the wide range of industrial environment, the FLXA21 is designed with the enclosure of plastic, stainless steel or stainless steel with corrosion-resistant coating. And, for hazardous location, the FLXA21 has approvals of ATEX, IECEx, FM, CSA and NEPSI.

*1: Use a 2-wire shielded cable with an outside diameter of 6 to 12 mm.*2: Connect the analyzer to ground. (Class D ground: 100 ohm or less) The way of connecting the grounding cable varies depending on the plastic housing and stainless steel
housing. In the case of the plastic housing, connect the grounding cable to the terminal of the power module inside,
and in the case of the stainless steel housing, connect the grounding cable to the terminal of the housing. Use a cable with an outside diameter of 3.4 to 7 mm for the grounding line of the plastic housing. Although, on the stainless steel housing, the ground terminal symbol is (protective ground), the ground is
really functional ground. *3: This line is connected to a distributor or 24V DC power supply.*4: Terminal numbers for each sensor module are shown below.*5: Two modules of the same kind of measurement/sensor type can be installed. When measuring inductive
conductivity or pH/ORP with the SENCOM sensor, only one module can be installed.*6: The terminal box may be necessary depending on the sensor cable length and the distance between the
analyzer and the sensor. The SENCOM sensor is to be connected directly to the analyzer without a terminal box.*7: Two outputs, output 1 and output2, of PH201G or SDBT are same signals.
