Why are semiconductor strain gauges more sensitive than metal strain gauges?
Semi-conducting materials changes in inter-atomic spacing resulting from strain affect the band gaps, making it easier for electrons to be raised into the conduction band while in metals, resistance change is mostly due to the change of geometry resulting from applied mechanical stress.
Difference between unbonded strain gauge and bonded strain gauge?
The essential difference is that the bonded strain gauges are bonded on to the specimen whose strain is being measured whereas the unbonded strain gauges are not bonded on to the specimen. As the bonded strain gauges are well bonded on to the specimen, the entire strain being experienced by the specimen is transferred to the strain gauge. However, the bonded strain gauges are affected by temperature changes and also due to transverse strains.For transverse strains and ambient temperature compensations, suitable circuits for compensation can be used using Wheatstone's bridge. The unbonded strain gauges cannot transfer the strain of the specimen to the strain gauge and hence it is used mainly for displacement, or pressure or force transducers. It is least affected by transverse strain and temperature compensation of unbonded gauges cis automatically eliminated using Wheatstone's bridge.
What is the purpose of a strain gauge?
A strain gauge is used to measure the strain of an object. It was invented by the inventors Edward Simmons and Arthur Ruge in 1938. There are several types of gauges (metallic, capacitance, photo-electrics and semiconductor gauges).
How do you calibrate strain gauges?
The strain gage indicates strain, and the stress is from Hooke's law; stress = modulus times strain so you need to know the modulus of elasticity
Where is constantan used?
In many typical installations, it is used in strain gauges.
Advantage and disadvantage of strain gauge?
Advantages and disadvantages of strain gauge
What is the inductance of Mechanical strain gauge?
"Mechanical Strain gauges" do not have inductance. There are many types of strain gauge: Mechanical, photoelastic, electrical etc.... Are you wanting the inductance of an electrical strain gauge? if so which type?

What converts mechanical energy to elecrical energy?
The most common is the generator. But don't forget the piezoelectric crystals in ignitors and strain gauges.

What are the advantage and disadvantages of modern Civilization?
The advantages of modern civilization is how easy it makes every day life. The disadvantages of it is there's a high chance of it collapsing due to its ecological strain.
What are the sensors used in weighing machines sensors?
strain gauges .
What are merits and demerits of strain gauge?
Merits: Strain gauges are highly sensitive and accurate in measuring very small changes in strain, making them suitable for precision applications. They are also versatile and can be easily attached to various materials for measuring strain in different environments. Demerits: Strain gauges can be affected by temperature variations, leading to inaccurate readings if not properly compensated for. They also require careful installation to ensure accurate measurements, which can be time-consuming and labor-intensive. Additionally, they can be prone to fatigue and need to be periodically checked and recalibrated.
