Equipment features

The lead-bismuth environmental gas phase oxygen control system developed by our company is mainly composed of a controller oxygen sensor, a voltmeter, a gas mass flow meter, and three gases.The oxygen sensor is used to monitor dissolved oxygen in lead and bismuth in real time. Its potential signal is collected with a voltmeter. The voltmeter communicates with the oxygen control controller. There is an automatic oxygen control program with AI intelligent algorithm in the controller. The user can switch to manual mode and automatically set the target oxygen potential (corresponding to a certain dissolved oxygen concentration).
