What is the difference between an instrument designer and an instrument engineer?

Despite the similar titles, there is quite a big difference between an instrument designer and an instrument engineer. An instrument engineer creates and monitors instrumentation to ensure optimum productivity. This instrumentation can be extremely complex and is utilized in manufacturing and other industries where computer-controlled equipment is necessary. Instrument designers do not typically create and monitor these kinds of sophisticated instruments and machines, but instead may use them within a plan for a project or job site during their work in the manufacturing or oil and gas industries, or may act as a technician if an instrument has trouble. Instrument designers are also not exclusive to the sectors that use instrument engineers.
