Information of instrumentation
The thermometers, barometers, and anemometers are used by government weather services to analyze the envirnmont. Similarly, water,gas,and electric meters are used to keep track of the consumption and cost of such commodities. Closer to the subject og this book, sensors are used to monitor and record important variable in a process.
The other and extremrly important application of sensors is that in which theunstrument servesas a comlonent of an automatic control system. The role of the sensors in an automatic control system is clearly seen the traditional block diagram.
