This chapter focuses attention on instrumentation, including measurement of temperatures, pressures, velocities, flow rates, motion, position, electric current, and some other variables. The instrumentation portion of a computer control system must be of high quality. There is no purpose served in choosing an elaborate computer to control an expensive mechanical or thermal system if the instrumentation is faulty. Perhaps instrumentation does not excite many engineers, but there can be no shortcut around careful choices and proper applications of instruments.
