Instrumentation For Engineers is a guide to the principles and practice of instrumentation, which has been designed to aid students and practising engineers who are not specialists in electrical subjects. The text concentrates on essential data, theories and the circuit designs required in project work and experimentation which includes the Fourier transform and correlation analysis. The work should be of particular value to undergraduate and BTEC chemical, mechanical, production, aero and marine engineers and also to applied science students and practising engineers involved in research or the control or monitoring of equipment.
