Directing his reference manual towards industrial control engineers, specialists in physical parameter measurement and control, and other technical personnel, Dunn (formerly of the Motorola Semi-conductor Products Sector and Ouachita Technical College) aims to present the essential facts for understanding current sensor technology, instrumentation, and industrial process control. After an introduction to units and standards, he covers the electronics and microelectromechanical systems used in sensors and process control; level, pressure, flow, temperature, humidity, and mechanical measurement sensors; regulators and actuators; signal transmission and the programmable logic controllers for conditioning sensors; different types of process control action and the use of pneumatic and electronic controllers for sensor signal amplification and control; and documentation as applied to instrumentation and control.
