Continuous Hydrogen Analyzer
Utilizing a unique, patented electrochemical sensor, the CHA outputs a continuous signal corresponding directly to the hydrogen concentration. Used in conjunction with real-time controls, alarms, and shut-off mechanisms, the CHA responds immediately to changing hydrogen levels for improved operations and safety.
Unlike thermal conductivity-based hydrogen analyzers, the CHA measures hydrogen directly and specifically. Built around a polymer membrane with proton-conducting properties, the CHA sensor detects hydrogen concentrations ranging from 400 ppm to 100% by volume in discrete ranges with ±1% accuracy or better (dependent upon sample concentration and reference gas composition).
Installation, Calibration, and Maintenance
Depending on the application, a sample gas stream is typically diverted to the CHA from the makeup gas line, reactor outlet, stabilizer offgas, or power generator casing. As it exits the analyzer, the sample stream can either be vented or returned to the process. Installation is easily completed by plant personnel.
