Endress+Hauser CA80SI Silica Analyzer Liquiline System

Description

Endress+Hauser CA80SI Silica Analyzer Liquiline System

The Endress+Hauser CA80SI silica analyzer is designed for continuous measurement of silica in aqueous solutions, especially in power generation and utility applications. By tracking trace silica in boiler feed water, steam, condensate, and other water-steam circuit points, it helps operators identify conditions that can contribute to glass-like deposits on turbines and other plant equipment. This early visibility supports timely process adjustments and helps protect equipment performance.

The analyzer is part of the Liquiline System and uses the standard heteropoly blue colorimetric method. Because this method is comparable with laboratory analysis, operators can more readily compare online readings with lab results during routine monitoring and validation.

Key Benefits of Silica Analysis

Early warning for plant protection

Silica monitoring helps assess boiler feed water purity and steam quality. It can also provide an early indication of condenser leaks, where silica-rich cooling water may enter the process, and help identify when ion exchangers are approaching exhaustion. These alerts give plant teams time to investigate and take appropriate corrective action.

In turn, timely monitoring can support more informed maintenance planning and process decisions, including the optimization of blowdown and ion-exchange regeneration schedules. The Endress+Hauser CA80SI silica analyzer helps users respond to changing silica levels before they become a larger operational concern.

Measurement method and dependable sample handling

The CA80SI uses colorimetric measurement based on the heteropoly blue method. Its combination of peristaltic and high-precision dispenser pumps supports stable sample delivery and reagent dosing, helping the analyzer provide consistent readings while keeping maintenance requirements low.

Automatic calibration and cleaning are available, and users can configure measuring, cleaning, and calibration intervals to suit their process needs. The analyzer is intended for particle-free samples, with a sample flow rate of 60 to 250 ml/min.

Flexible Configuration and System Integration

The analyzer offers two measuring ranges: 0 to 500 µg/l (ppb) and 50 to 5000 µg/l (ppb). Depending on the configuration, it can support one, two, four, or six measuring channels, allowing users to monitor several sample points with one system.

For changing monitoring requirements, the Endress+Hauser CA80SI silica analyzer can be expanded with up to six sample channels. It can also connect to as many as four digital Memosens sensors, providing an upgrade path toward a broader measuring station. Available communication options include two 0/4 to 20 mA outputs, with optional Webserver, Modbus, EtherNet/IP, and PROFIBUS DP connectivity for integration into process control systems.

Advanced diagnostics and remote access via a web server can help teams investigate errors more efficiently. The optional Liquiline Edge Module CYY7 can transfer process data to Netilion independently of the fieldbus, enabling remote data overview and access to IIoT services.

Typical Applications in Power and Utilities

The CA80SI is intended for silica determination in boiler feed water and for monitoring water-steam circuits and condensate. It can also support monitoring and optimization in reverse osmosis and desalination processes. In power plants and utilities, these measurements help maintain water quality and identify changes that may affect turbines, ion exchangers, and related equipment.

Its process conditions include a temperature range of 5 to 45 °C and a pressure range of 1 to 5 bar. The ambient temperature range is 5 to 40 °C. Confirm that the sample conditions, selected measuring range, and channel configuration match the intended installation before specifying the analyzer.
