Temperature Controller

The temperature controller consists of a signal conversion and display module, a setting module, a comparison and computation module, and an output module. When the temperature sensor converts the actual temperature into an electrical signal (Ω or mV) and sends it to the controller, the signal conversion and display module converts the signal into a digital readout or analog indication. The internal comparison module then compares the measured value with the setpoint from the setting module (or performs PID computation), and the output module sends control signals to actuators such as contactors, solid-state relays, or power controllers. These actuators then regulate the operation of the heater or cooler accordingly.
