Yokogawa FLXA402 Conductivity Analyzer | 4-Wire, PROFIBUS-PA, Panel Mount, Dual Alarm

Yokogawa FLXA402 analyzer specifications. 4-wire conductivity analyzer, PROFIBUS-PA, 4-electrode, panel mount, dual alarm.

Product Overview

The Yokogawa FLXA402-A-B-AB-P1-NN-A2-NR-N-N-N-NN is a 4-wire conductivity analyzer configured for digital fieldbus communication. Part of the FLXA40 series, it uses a 4-electrode measurement method for high-accuracy conductivity, resistivity, or concentration analysis. This model communicates via the PROFIBUS-PA protocol, providing direct digital integration into modern plant control networks, and includes dual alarm relay outputs for local control.

Key Features

PROFIBUS-PA Communication: Direct digital integration for multivariable data access and configuration
4-Electrode Technology: Accurate measurement over a wide range, immune to cable effects
Bus-Powered: Single cable for power and data simplifies wiring
Dual Alarm Relays: Two configurable contact outputs for local control or annunciation
Automatic Temperature Compensation (ATC): Ensures accurate readings
Intuitive Local Interface: Large backlit display for setup and local monitoring
Comprehensive Diagnostics: Sensor and process diagnostics accessible via the fieldbus
Robust Panel Design: IP66 front for harsh environments

Applications

Water purity monitoring in plants with PROFIBUS-PA networks
Concentration control in chemical processes
Boiler feedwater and cooling water treatment
CIP monitoring and control in hygienic industries
General conductivity analysis in networked process automation

Important Notes

Requires a PROFIBUS-PA network and compatible controller (DCS/PLC)
A compatible 4-electrode conductivity sensor and cable must be purchased separately
The relay outputs are dry contacts; external power is required to switch a load
Configuration is performed via the fieldbus network or the local interface
The "P1" in the model code specifies the PROFIBUS-PA communication option
