Yokogawa FLXA402 Conductivity Analyzer | 4-Wire, 4-Electrode, 4-20mA+HART, Dual Alarm

Yokogawa FLXA402 analyzer specifications. 4-wire conductivity/resistivity analyzer, 4-electrode, 4-20mA+HART, dual alarm, panel mount.

Product Overview

The Yokogawa FLXA402-A-B-AB-C5-NN-A2-NR-N-R-N-NN is a versatile 4-wire analyzer from the FLXA40 series, configured for conductivity, resistivity, or concentration measurement. It utilizes a 4-electrode measurement method for high accuracy and wide rangeability, and provides a 4-20mA analog output with HART communication, along with dual alarm relays. This panel-mount model is designed for precise liquid analysis in industrial process control.

Key Features

  • 4-Electrode Measurement:​ Provides accurate readings over a very wide range, unaffected by cable resistance and polarization

  • HART Communication:​ Enables remote configuration, diagnostics, and digital data access

  • Dual Alarm Relays:​ Two configurable contact outputs for process control or alarms

  • Automatic Temperature Compensation (ATC):​ Built-in for accurate measurement across temperature variations

  • Intuitive Interface:​ Large backlit display and simple menu navigation

  • Flexible Calibration:​ Multiple calibration methods (standard solution, cell constant, etc.)

  • Robust Design:​ Suitable for demanding industrial environments

  • Extensive Diagnostics:​ Monitors sensor health, cleaning requirements, and process conditions

Applications

  • Water purity monitoring (ultrapure water, demineralized water)

  • Concentration measurement in chemical processes (acids, bases, salts)

  • Boiler blowdown and cooling water conductivity control

  • CIP (Clean-in-Place) monitoring in food & beverage and pharmaceutical industries

  • Wastewater and effluent monitoring

Important Notes

  1. Requires a compatible 4-electrode conductivity sensor and sensor cable, purchased separately

  2. The specific measurement mode (conductivity, resistivity, %) is configurable

  3. HART communication requires a minimum loop resistance of 250Ω

  4. The alarm relays are dry contacts; external power is required to switch a load

  5. Proper sensor selection (cell constant, material, temperature rating) is critical for application performance
