There are a number of outputs that are used with temperature and process controllers, some of the common ones include, solid state relay drivers, linear along outputs, relay outputs, and triac. The relay output commonly is a single pot double throw relay which comes with a DC voltage coil.
The controller works by isolating the contacts using the energy added to the relay coil. This lets the contacts make use of the external voltage source, which ultimately powers the larger heating contactor. The contacts used in the process are designed to control the output in addition to handling the process timing and proper execution.
Temperature and process controllers are an integral part of the workings of a number of industries. The best industrial functions need proper maintenance of process schedules and temperature levels both of which are controlled by these controllers.
Food and Beverage Industry Packaging
The packaging industry is heavily dependent on temperature maintenance for proper functioning. The machinery used in packaging which includes hot melt functions, glue applicators, seal bars, label applicators, and shrink wrap tunnels are designed to operate at a certain temperature and to process for a set length of time. Both of these processes are regulated by temperature and process controls. Process controllers control the process time limit, while temperature controllers ensure that the wanted temperature is maintained throughout.
Food and beverage industry
The food and beverage industry is another place where temperature plays a vital role. The use of temperature and process controllers in the industry is for a variety of purposes such as blending, sterilization, brewing, cooking, baking ovens etc. Temperature and process controllers make sure that the temperature is regulated and optimum performance ensured.
Temperature Control Panels for the Plastic Industry
The plastic industry makes a slightly different use of temperature controllers than boilers or kilns. They look to use them in relation to controlling portable chillers, dryers, hopers, extruding equipment and molding. As far as the extruding equipment is concerned, the use of process controllers in combination with temperature controllers is to precisely monitor and control temperature at the different critical points in its operation.
Temperature Control Panels for Heat Treating Applications
One of the most common uses of temperature and process controllers are in heating ovens or in heat treating applications such as boilers, exchangers, ceramic kilns and different types of furnaces.
