Controllers - Process, TemperatureProcess temperature controllers are electronic devices that are used to monitor and control the temperature of a process or system. These controllers typically use sensors, such as thermocouples or resistance temperature detectors (RTDs), to measure the temperature of the process, and use this information to control a heating or cooling device, such as a heater or cooling fan, to maintain the temperature at a predetermined setpoint. Process temperature controllers are commonly used in a wide range of industrial and commercial applications, such as manufacturing, food processing, and chemical processing. These controllers are typically small and compact, and can be easily integrated into a wide range of temperature control systems.
