What is the FLXA402 Multi-Channel 4-Wire Analyzer?
The FLXA402 is an industrial analyzer (or “converter”) designed by Yokogawa for continuous online measurement of various liquid parameters. It supports 4-wire sensor connections and can handle multiple sensors (up to five) simultaneously, thereby reducing the number of separate analyzers needed in a plant.
Because of its modular design, it can support sensors for different measurement types (pH, ORP, conductivity, dissolved oxygen, etc.) in one unit.
Its architecture allows for maintenance or sensor replacement without shutting down the entire measurement line, which is valuable in process control environments where uptime is critical.
Key Features & Advantages
Here are some of the standout features and advantages of the FLXA402:
|
Feature |
Description / Benefit |
|
Multi-sensor capability |
Can connect up to five sensors to a single analyzer, allowing heterogeneous measurements (pH, conductivity, DO, etc.) from one unit |
|
Redundancy & uninterrupted measurement |
Allows sensor maintenance or replacement without interrupting measurement (i.e. “interruption-free measurement”) |
|
Modular design |
Sensor modules are swappable depending on measurement type (pH/ORP, contacting conductivity, inductive conductivity, dissolved oxygen, etc.) |
|
Advanced diagnostics / sensor wellness |
Supports monitoring of sensor impedance, slope, electrode condition, contamination, etc., enabling predictive maintenance |
|
Color touch HMI / user interface |
Touchscreen interface, intuitive menu structure (supports multiple languages) for easier setup and monitoring |
|
Flexible connectivity & data mobility |
Options include SD card, Ethernet (for data transfer and remote service) |
|
Robust construction |
Housed in aluminum die-cast body with urethane coating to resist corrosive environments |
|
Wide measurement capabilities |
Handles a variety of inputs: pH/ORP, contacting conductivity (SC), inductive conductivity (ISC), dissolved oxygen (DO), and 4–20 mA signals |
|
Calculation & customization |
Dual sensor measurements allow customized calculated data (for example combining two sensor readings in a formula) |
