Compact Controller

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 set point, and provides an output to a control element. The controller is one part of the entire control system, and the whole system should be analyzed in selecting the proper controller. Compact controllers take less space and are useful for process where you dont require too much processing power.

Two-State Controller

The 2-state controller (ON/OFF controller) switches the output when the setpoint is reached. If the value falls below the setpoint by a certain adjustable tolerance (xsd, switching differential, hysteresis), then the output is switched on again. It therefore only has two switching states. It is used in temperature control applications where the heating or cooling is only switched on or off. A 2-state controller with dynamics can, however, also operate with a P, I, or D component.

Temperature Controller

For accurate control of the process temperature without constant operator involvement all industrial thermal process relay upon a controller. The controller gets is inputs from contact temperature sensors like thermocouple, RTD or from a non-contact temperature sensor like an infrared temperature sensor. The controller transmits an electrical signal (current or voltage) to a power switch device which can be a simple relay, a solid state relay or a SCR (Silicone Controlled Rectifier). A temperature controller is an device that is used to control temperature. It does this by first measuring the temperature (process variable), it then compares it to the desired value (set value). The difference between these values is known as the error (Deviation). Temperature controllers use this error to decide how much heating or cooling is required to bring the process temperature back to the desired value. Once this calculation is complete the controller will produce an output signal that effects the change required. This output signal is known as the (manipulated value) and is normally connected to a heater, control valve, fan or some other "final control element" which actually injects or removes heat from the process.

SCADA

Supervisory Control and Data Acquisition (SCADA) refers to industrial control systems (ICS) that are employed to control and keep track of equipment or a plant in industries like water and waste control, telecommunications, energy, transport, and oil and gas refining. SCADA is a computer system used to gather and analyze real-time data. This data is processed by the computer and is presented on a regular basis. SCADA also saves and make logs for every event into a log file that is saved on a hard drive or is sent to a printer. SCADA gives warnings by sounding alarms if situations develop into hazardous scenarios.
