Strain and Force Measurement
The design of load bearing components for machines and structures are an essential task
of the engineer. Proper design of these load carrying devices such as shafts, mounts,
pressure vessels, support structures etc. involves d

INSTRUMENTATION ELECTRONICS
Often, it is through the use of electronic instrumentation that an engineer is able to obtain
the measurements for the system being studied. The primary sensing element and the
variable conversion element of a measuring inst

DIGITAL INSTRUMENTATION PRINCIPLES
Computers are used in almost all aspects of engineering. Measurement and control are no
different. While most sensors electronic sensors provide a continuous voltage or current
signal, microprocessors require digital sig

Experimental Test Plan and Calibration
1. Experimental Test Plan
The design of an experiment requires more than attaching some instruments and
turning on the power. Relevant information can only be obtained from a well designed
measurement test plan. A te
