Abstract
In this experiment, we experimented and worked with different types of temperature sensors as
Liquid Filled Glass Thermometers, Gas (Vapor Pressure) and Bi-Metal Thermometers and
Thermocouples and we used them after calibrating to measure the temperature and due to our
results, we graphed the relationship between the 3 instruments to discover the error study while
as comparing them with respect to uncertainty from our calculations.

Introduction & theory
What is the Temperature Measurement and Calibration?
Temperature measurement (as well called as thermometry) refers to the practice of determining
the current local temperature for immediate or future application. Temperature trends may be
assessed using datasets comprised of repeated standardized observations. Temperature
calibration relates towards the calibration of every equipment used for a temperature-
measurement systems. The temperature sensor itself, which is often a platinum resistance
thermometer (PRT or PT-100), thermistor, or thermocouple, is usually referred to as the most
integral part. These thermometers' readings are taken by "thermometer readout" machines, which
detect their electrical outputs and transform them to temperature using the International
Temperature Scale of 1990. (ITS-90). [1]
The Celsius temperature scale: Celsius, often known as centigrade, is a temperature scale that
ranges from 0° to 100° for the freezing point of water and from 0° to 100° for the boiling point of
water. It was invented in 1742 by the Swedish astronomer Anders Celsius and is frequently
referred to as the centigrade scale due to the 100-degree gap between the designated points. [2]

The Kelvin temperature scale: Kelvin (K), is the base unit of the study of our course
thermodynamic and it’s used in measuring temperature in thermodynamics also temperature
measure for the International System of Units (SI). This unit was originally described as
100/27,316 of pure water's triple point (equilibrium between the solid, liquid, and gaseous
phases). The kelvin is also the fundamental unit of the Kelvin scale, which was named after
British scientist William Thomson (known as Lord Kelvin). [3]
