Product Description
The FLXA21 (Part Number: FLXA21) is a high-performance, 2-wire loop-powered liquid analyzer engineered for continuous industrial process measurement. As a pioneer in dual-channel technology for loop-powered transmitters, the FLXA21 supports the simultaneous connection of two sensors of the same measurement type, enabling sensor redundancy or differential analysis within a single device.
Designed with a modular architecture, the FLXA21 allows sensor and measurement modules to be replaced independently, significantly reducing lifecycle cost and simplifying field maintenance. A high-resolution touchscreen human–machine interface (HMI) with multilingual support enhances usability in global industrial environments.

Core Features
Dual Sensor Redundancy
Supports two identical sensors per measurement type. Automatic switchover to the secondary sensor ensures uninterrupted process monitoring in the event of sensor failure.
Advanced Diagnostics
Real-time diagnostics include sensor impedance tracking, sensor health monitoring, and predictive maintenance indicators, displayed via an intuitive bar-graph interface.
Modular Scalability
Measurement functionality is defined by the “Type” code in the model configuration, allowing flexible selection of pH/ORP, SC, ISC, or DO without replacing the entire transmitter.
Hazardous Area Compatibility
Certified for use in hazardous environments with approvals including ATEX, IECEx, FM, CSA, and NEPSI. Intrinsically Safe (IS) and Non-incendive versions are available.
Application Scenarios
-
Chemical and petrochemical processing
-
Oil & gas production and refining
-
Power generation and utilities
-
Water and wastewater treatment
-
Pharmaceutical and specialty chemical plants
The FLXA21 is particularly well suited for applications requiring high availability, measurement redundancy, and advanced diagnostics within a compact 2-wire architecture.
