1000L快速温度变化试验箱控制系统设计

The design of control system for 1000L rapid temperature variation test chamber

设计了基于PLC和温度控制器的1000L快速温度变化试验箱自动控制系统,其操作简单、稳定可靠,满足了试验箱的快速降温和快速升温的工作要求;改善了控温区的温度过冲现象;提高了试验箱的控制精度。

Based on PLC and temperature controller, an automatic control system of IO00L rapid temperature variation test chamber was designed. The system was easy for operation and its features were stability and reliability. It can meet the working requirements of fast heating and fast cooling for the test chamber, improve the temperature overshoot condition of temperature con- trolled zone, and increase control accuracy of the test chamber.
