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 difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What are Types of strain gauge?
the types are1> mechanical strain gauge like single bonded rosette2> electrical resistance strain gauges3> elliptical c/s gauge. e..g bourdon tube etc.
What is the difference between dynamic strain aging and strain aging?
Strain aging could be described as " normal wear and tear " or the fatigue that is experienced under normal conditions, whereas Dynamic strain would be an out of the normal range stress condition like a one time over stress condition where the sum of much strain aging is experienced in one " dynamic" occurrence.
What is the difference between E and nu in engineering geology?
E is generally taken to be the elastic constant known as Young's modulus which describes the relationship between axial stress and axial strain where Hooke's law still applies (i.e. linear elasticity). Nu is Poisson's ratio which is the relationship between axial strain and radial or transverse strain. For more information, please see the related link.
What is the deformation between strain and deformation?
First of all i guess the right question is difference between strain and deformation. Actually the strain is deformation in a material over its original length. So strain is a relative quantity while deformation is simply change in length, hence absolute and is new length minus original length. Strain= deformation(L2-L1)/original length(L1)
Describe metallic bonded strain gauges?

What is the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What is difference between strain gauge and extensometer?
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
What are Types of strain gauge?
the types are1> mechanical strain gauge like single bonded rosette2> electrical resistance strain gauges3> elliptical c/s gauge. e..g bourdon tube etc.
What is the difference between a muscle strain and tendons?
A sprain is an injury in which a muscle is overstretched or torn. Tendinitis is an injury that occurs when a tendon becomes inflamed or torn. That's the difference between a muscle sprain and tendinitis.
What is the difference between an old and a new strain of DNA?
An old strain of DNA refers to the original sequence of genetic code, while a new strain refers to a mutated or altered version of the DNA. Mutations in the DNA sequence can lead to differences in characteristics or functions of an organism.
What is the difference between dynamic strain aging and strain aging?
Strain aging could be described as " normal wear and tear " or the fatigue that is experienced under normal conditions, whereas Dynamic strain would be an out of the normal range stress condition like a one time over stress condition where the sum of much strain aging is experienced in one " dynamic" occurrence.
What is the difference between and sprain a strain and a fracture?
A strain is an overstretched or "pulled" or torn muscle. a sprain is an overstretched or torn ligament (holds bones together at a joint), and a fracture is a crack, chip, break or crush of a bone.
What is the between a strain and a sprain?
Strain - muscle/tendons Sprain - ligaments
What is the Difference between a muscle strain and a muscle sprain?
NO, You misunderstand the definitions. A sprain affects a joint and a strain affects a muscle E.G. I sprained my ankle and strained my calf. NO, You misunderstand the definitions. A sprain affects a joint and a strain affects a muscle E.G. I sprained my ankle and strained my calf.
