INFORMATION AND INSTRUMENTATION
An instrument is devices that used to measure and control a process variable.An instrument conerting the parameter that we need to measure into a readable format.
A system is euipment or a group of equipments functiining together to create a reault or a product with in a controlled condition. As an example considees a computer system, a computer system has its ow control and which performing according to our instructions and give output. A human body has itd control and we can say it as a system. Concerned to a doctor a human body is purely a control system, and when that control fails peoples arr visiting a doctor. When the temperature of the human body increases people tells that they feel fever.
But actually what is happening...? When micro organisms or virus infects a man, thetemperature of the body increases by the control of the body system. Thus the bodies itself having a temperature control. Also the lood pressure of a healthy man is controlled with in the limit of 120/80. When the blood pressure of the body going out the limits,rushing to the hospital. Doctors using many instruments to analyze and measure the disease of a man.
Another system is an automoblie that is having many controls. For examble ,a geared motorcycle,having clutch, accelerator, brake,gear etc....
Thesare exterior controls, used by the rider. The speed is increased by accelarator and decreased by brake. Thus the riders getting proper control. Grears adjust the power driver to the wheel. The rider measures the speed through hid eyes and controls the speed.
In industries and medical field many systems are there. In all the industries that may be continuously operation like petroleum based refunery or the industries for preparing medicines, which are working as batches, all are have some optimum controlled cinditions and cintrolled to that pounts. For all industry, which is producing polyethlene, the the optimum controlled condition id the ethylene gas at a compressed pressure if 21kg/cm2 and at a low temperature to the required set point. The polymerization is an exothermic process, which produces heat and the temperature will be produced. So raw metirials must be cooled and bring to 790 for the best quality product with the maximum efficiency.
