Practical Case

In a chemical plant, the SPASI23 is used to monitor the temperature and pressure of reactors. It accurately collects analog signals from temperature and pressure sensors and transmits them to the central control system. Once, when a reactor’s temperature suddenly rose abnormally, the SPASI23 quickly detected the change and sent an accurate signal to the control system. The control system promptly took measures to adjust the cooling system, preventing a potential accident and ensuring the safe operation of the production process.
