It is an instrument used to control temperature. The temperature controller takes an input from a temperature sensor and has an output that is connected to a control element such as a heater or fan.
To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or setpoint, and provides an output to a control element.
Standalone electronic temperature controls for household and commercial refrigerators and freezers, for management of energy consuming functions. Depending on the type of controls, functions are also available for regulating defrosting and fan operation.
ERC and EKC electronic controls are designed to manage energy consuming functions in commercial refrigerators. Depending on the type of controls, functions are also available for regulating defrosting and fan operation.
