An instrumentation engineer(IE) designs, develops and installs different types of devices for various industries. Say you're an instrumentation engineer in the medical industry. You could create and develop a device to monitor blood sugar. You'd first work on the design, then develop the device. You would then check the developed device to make sure it works correctly. If it works correctly, you would install it in hospitals, clinics or wherever else it is required.
We all own smartphones! Each of these smartphones is different in size, shape and features. As an instrumentation engineer, you would work in a company like Samsung, Apple or Nokia to design the instrument that controls how various parts of the machine interact with each other. Take something as simple as your alarm clock on the phone. If you set the alarm at night and switch off your phone, your phone is likely to get switched on when the alarm rings in the morning. An instrumentation engineer works on these sensors and reactions. It’s not just bio-med or electronics, Instrumentation engineering can be applied to large-scale projects too. You could work in the oil and gas industry, power industry, robotics, airport automation and many more.
If a device is a body, the instrumentation is the brain that controls it. It is the automatic sensor that, for example, switches off your air-conditioner when it's in auto mode. Wondering how? A sensor continuously “reads” the current temperature. Once it matches the ideal “desired” set point- it instructs the device to switch off.
As an Instrumentation Engineer, you will be immersed in algebra and math. You will learn how instruments work, how they react to physical parameters, and how to control them. You're the one who deploys 'automation' to make lives easier. Thanks to your creations, we can now get a 10-day job done in a matter of minutes and a 10-man job done by a mere machine!
