Description
The Yokogawa FLXA402T is a four-wire modular liquid analyzer for turbidity, chlorine, pH and conductivity measurement systems. It is intended to combine compatible water-quality sensor inputs in one operator interface rather than requiring a separate analyzer for every loop.
Verified technical overview
| Analyzer architecture | Four-wire analyzer with modular, replaceable sensor modules |
|---|---|
| Sensor capacity | Up to two compatible sensors; module selection determines the permitted combination |
| Measurement choices | Turbidity, chlorine, pH, conductivity and 4–20 mA input, depending on installed modules |
| Operator interface | Color HMI with touchscreen menu; Yokogawa lists eight display languages |
| System pairing | Used with compatible SENCOM4.0 detector and sensor units such as TB820D, TB830D, FC800D or RC800D |
Engineering selection checklist
Define both measurement points, required sensor modules, outputs, communications, power supply, enclosure location and cleaning or calibration functions. Confirm the exact module combination in the current Yokogawa ordering information before quotation.
| Process data | Measurement objective, normal/minimum/maximum value, medium chemistry, temperature and pressure |
|---|---|
| Installation | Sample or immersion arrangement, connection, cable distance, cleaning and maintenance access |
| System interface | Compatible analyzer or host, power, output, communication and alarm requirements |
| Documentation | Confirm the current Yokogawa general specification and complete order code before purchase |
Industry application guidance
Typical engineering uses include drinking-water treatment, wastewater discharge monitoring and utility-water quality. In food, beverage or pharmaceutical utilities, verify hygienic boundaries and sample-system suitability separately; the analyzer alone does not establish hygienic compliance.
