Question

a dilatometer is an apparatus used to measure​

Answer 1

Answer:

A dilatometer is a scientific instrument that measures volume changes caused by a physical or chemical process.

Explanation:

• A familiar application of a dilatometer is the mercury-in-glass thermometer, in which the change in volume of the liquid column is read from a graduated scale.
• A dilatometer is a measuring device for recording the dimensional change of a material in a changing thermal environment. The dimension change is recorded as a function of time and temperature and is used to quantify material properties for applications in research and production facilities.
• The dilatometer instrument turns a mechanical change in dimension into a digital signal using a variety of methods including:

1. Linear Velocity Displacment Transducer (LVDT).
2. Strain Gauge.
3. Michelson Interferometer .
4. optical Images

Answer 2

Answer:

Measurement of dimensional changes  in material as a function of temperature.

Explanation:

• A dilatometer is an apparatus used to measure​  precision instrument for the measurement of dimensional changes in material as a function of temperature.
• The first optical dilatometer was invented by Abbe and Fizeau in the second half of 19th century.
• Dilatometry is a powerful analytical technique to determine the dimensional changes in a material as a function of temperature
• Dilatometry is used to test a wide range of materials such as traditional and advanced ceramics, glasses, metals, and polymers.
