摘要
由可编程控制器实现温度的控制,温度传感器测量出水箱的温度,再通过变送器件把温度信号转换为相应的电信号。通过比较测量的温度与原设定的温度值进行控制,当液体的温度低于设定温度时,将产生低温报警并通过改变加热电阻的输入功率来增加液体的温度,自动实现PID调节,当温度高于设定值时,产生高温报警,并调节温度以达到要求。
Programmable controller is applied to realize the control of the temperature, temperature sensors measure the temperature of the water tank,and then The temperature signal is converted to the corresponding electrical signals through the transmitter,By comparing the measured temperature value with the original setting to control.When the liquid temperature below the set temperature,Will produce low-temperature alarm and heat resistance by changing the input power to increase the temperature of liquid,and realize PID regulation automatically.When the temperature is higher than the set value, produce high temperature alarm,and adjust the temperature to meet the requirements.
