ABB AX460 Liquid Analyzer Transmitter

Overview

The ABB AX460 process analyzer from the AX400 family is designed for continuous liquid analysis in demanding industrial environments. It provides accurate monitoring of pH, oxidation-reduction potential (ORP/Redox), and conductivity using one or two sensor channels. The transmitter integrates measurement, control, and diagnostics in a compact IP66/NEMA 4X enclosure suitable for both panel and field installations.

Built for process reliability, the analyzer incorporates self-diagnostics, configurable outputs, and integrated control features. These capabilities make it suitable for applications requiring stable chemical monitoring, automated dosing control, and dependable long-term operation.

Key Technical Specifications

Measurement and Control Capabilities

The ABB AX460 transmitter combines analytical measurement with integrated process control features. Its dual-channel architecture allows simultaneous monitoring of two analytical parameters or two sensors of the same type. This flexibility simplifies installation and reduces the need for additional transmitters.

The integrated PID control functionality enables the analyzer to directly regulate chemical dosing systems, making it suitable for automated process loops such as pH neutralization or oxidation-reduction control.

Mechanical and Environmental Characteristics

The instrument is housed in a corrosion-resistant enclosure rated IP66/NEMA 4X, ensuring protection against dust, moisture, and harsh environmental conditions. The front display provides clear visibility in industrial environments, while the internal design supports convenient wiring and maintenance access.

The compact housing minimizes panel space requirements while maintaining high durability for long-term operation in industrial plants.

Typical Industrial Applications

Water and wastewater treatment facilities for pH and conductivity monitoring
Chemical manufacturing processes requiring Redox control
Food and beverage production for process quality monitoring
Pharmaceutical manufacturing for regulated pH measurement systems
Industrial utilities and cooling water systems
