Using A Temperature Pid Controller In The Shower
A temperature pid controller is an instrument that is connected to any liquid or gas source which needs the temperature and flow regulated and maintained under certain parameters. The computer chips inside the pid monitor changes in flow and temperature constantly and use numbers and probabilities to calculate and predict changes so the corrections can be done ahead of time.
The process requires extremely accurate temperature controls and humidity controllers to be able not only to predict changes but to correct them in time. A common way to explain and understand how a temperature pid controller works takes place every morning when you are about to take a shower. If you want abundant hot water you will open the hot water a lot and use the cold water just to add a little touch so you do not scald yourself with it.
Your hands act as the temperature control systems when you touch the water to make sure it has the exact temperature you want in it. Your hands and the water knobs are the pid regulation, regulating the flow of cold and hot water to get the exact combination. After the initial pid adaptation, when you opened the hot water wide, the remaining adjustments are short and small so as not to over adjust.
This is the basic explanation for a pid process; the only problem with our explanation is that you have to regulate the water temperature every day before your shower. A temperature pid controller remembers the settings and continues adjusting and making chances every time a new factor comes up. It not only controls the flow of liquids in a general direction for a specific purpose but it can also open and close temperature control valves to cool or heat up specific liquids. Many different and possible variables have been introduced into the pid memories and with every incident or change it makes; more variables are stored keeping the system updated permanently.
Very accurate and immediate electronic temperature controller equipment is necessary to make minute and instant adjustments to temperature and flow. Pid controllers keep temperature levels within less than one eighth of a degree of the exact temperature desired. Taking into account that these are flowing liquids, many times at certain speeds and variable amounts it is a great feat these systems do to keep temperatures within the above mentioned range.
These control systems are used very much in nuclear electric plants. They are used to keep tabs and control the temperature of the liquids cooling the nuclear core. This is a great responsibility for any type of apparatus to have; failure could cause a major meltdown and kill millions of people. Temperature pid controller equipment is used everyday around the world to make our lives easier and to erase some of the possibilities of human error out of vital and delicate systems and operations.
