Introduction to Mechanical Instrumentation
Mechanical measurement plays a vital role in the accuracy and reliability of mechanical systems in the study of engineering. Accurate and reliable measurements are crucial for designing, analyzing, and optimizing mechanical systems for optimal performance. Measurement is always of fundamental significance to the practicing engineers. For the development of any mechanical design procedure, experiments are of paramount interest. Accordingly, measurement and correct interpretation of the concerned observation are necessary part of any standard engineering task and also R&D. Mechanical instrumentation reviews units of measurement, standards of measurement, and calibration. Measurement and instrumentation are used in various applications including home appliances, vehicles, and industrial processes to monitor and control parameters and improve operations.

This chapter describes the three physico-mechanical metrology streams; temperature and humidity, optical radiation and acoustic and vibration metrology. Among the seven base SI units, temperature and optical radiation encompasses the two SI units while acoustic comprises only derived parameters. Temperature metrology includes realization and dissemination of temperature and humidity S. Yadav (B) · D. D. Shivagan · K. Bapna · V. K. Jaiswal · P. Sharma · S. Saha · M. Singh · N. Garg · K.
