About this book
This book is written for the instrumentation and control engineers, technicians, and managers in nuclear power plants. It focuses on process temperature and pressure sensors and the veri?cation of these sensors’ calibration and response time. It also provides examples of typical problems and solutions with temperature and pressure measurements in nuclear power plants.
