Factories nowadays, no matter what they produce, follow mostly an automated process through which things move forward from one stage to the other with minimum human intervention. Technology advancements have made it possible to have routinary tasks such as adjusting screws, classifying items according to their size or similar tasks to be done by machines without the need of having an operator worker intervening.
However, no matter how much we trust in the machines and how much we rely on their accuracy, it is still important to be vigilant over the production process and avoid living it unattended.
This is why there are process sensors that play an important role in aiding humans to verify that that automated manufacturing process is being followed without problems or inconvenient. Process sensors ensure that each machine is performing its task correctly and that the final output product meets all the expected requirements and conditions as regards humidity, shape, size, weight or whatever you need to control.
There are different types of process sensors, according to which part of the manufacturing process they have to supervise and what needs to be monitored.
Process sensors are very important because they provide very useful feedback about the condition of the manufacturing process in itself. Thus, the process can be run smoothly and operators can be warned easily if any corrective measure or adjustment needs to be implemented. These kind of supervising devices can be contact or contact-less, meaning that they do not need to touch the parts, environment or products they are checking but that anyway can give useful information to the system. The food industry is one of the main users of process sensors in the manufacturing process of crackers, cereals, potato chips, instant coffee, soya products, powder drinks, roast and ground coffee, tea and milk powders. They are also used in the paper industry, chemicals and animal food products industry.
As it can clearly be seen, process sensors are very advantageous for those industries whose processes can be automated but that, at the same time, require each step of the process to comply with certain requirements such as humidity level, size of the parts, their weight and so on. These devices are especially important as they help to perform and speed up a supervision that not only would be nearly impossible to do for the human eye but also that needs to be done at a specific pace so that the products that are being manufactured do not get delayed.
