Working & Applications Of Temperature Controllers Like Eurotherm 3208

Posted by michaelalbert on May 19th, 2017

Temperature controllers are required in any situation requiring a given temperature stay stable. This can be the case when the object is required to be heated, cooled or both and to remain at the target temperature (set point), regardless of the changing environment around it.

There are two fundamental types of temperature control; open loop and closed loop control.

Open loop is the most basic form and applies continuous heating/cooling with no regard for the actual temperature output. It is analogous to the internal heating system in a car.

Whilst a closed loop system, is far more sophisticated than former one. In a closed loop application, the resultant temperature is perpetually measured and adjusted to maintain a constant output at the desired temperature. Closed loop control is always conscious of the output signal and will feed this back into the control process.

Thermostat is a typical example of a temple controller found in homes. It holds the temperature at a specified set of value.

Its Applications:

In industry, temperature controllers works much the same as they do in common household applications. Fundamentally, a temperature controller caters for control of  industrial or laboratory heating and cooling processes. In a typical application, sensors measure the actual temperature. This sensed temperature is constantly compared to a user setpoint. When the actual temperature deviates from the set temp, the controller generates an output signal to activate other temperature regulating devices such as heating elements or refrigeration components to bring the temperature back to the original value.

One of the trustworthy controllers used commonly is manufactured by Eurotherm . Models such as Eurotherm 3208 , Eurotherm 3504,  Eurotherm SUB24-R4 etc offers precision control of a number of process variables, including temperature. It comes with a host of other features that make it the most flexible product in its category.

Temperature controllers are used in a wide variety of industries to manage manufacturing processes or operations. Some common uses for temperature controllers in industry include plastic extrusion and injection molding machines, thermo-forming machines, packaging machines, food processing, food storage, and more.

Temperature controllers are major building block ,utilized  in ovens and in heat-treating applications within furnaces, ceramic kilns, boilers, and heat exchangers.

In the packaging world, machinery equipped with seal bars, glue applicators, hot melt functions, shrink wrap tunnels or label applicators must operate at designated temperatures and process time lengths.Temperature controllers regulate these operations with high precision to ensure a high quality product output.It is also used in healthcare industry and food & beverages processing applications as well.

We hope the article helped you understanding the nature, working and industrial applications of a temperature controller as such.
