Summary
The strain gauge laboratory session had a lot of aims and one of the main aims was to provide us with experience in using circuits based on operational amplifiers and examine the characteristics of these circuits when they amplify DC signals. Another aim was to also investigate the use and characteristics of resistive strain gauges. The overall objective was to understand the how these widely used transducers are used and how they behave. This will be done through custom pre-built electronic circuits which will then be used to amplify signals from a resistive strain gauge when weighed down with washers.

Introduction:
The aim of the laboratory was to gain experience in the use of Operational-Amplifiers and the study of their characteristics. This report will cover the method used to study Op-Amps and analyse the results thus explaining and showing the behaviour and Op-Amps. This laboratory had 3 sections looking at a non-inverting amplifier, inverting amplifier and a strain gauge bridge (differential op-amp) respectively.
Where:
• V+ : non-inverting input
• V−: inverting input
• Vout: output
• VS+: positive power supply
• VS−: negative power supply
Where:
• V+ : non-inverting input
• V−: inverting input
• Vout: output
• VS+: positive power supply
• VS−: negative power supply
Operational-Amplifiers are key components in many electronic circuits and were first used in analogue computers to carry out mathematical functions such as addition, multiplication, and integration. Ideally the op-amp only amplifies the difference in voltage between the two inputs.
Vout (Output) = [V+ (+ Input) – V- (- input)] X Gain
There are 3 main op-amps available and these 3 will
