Feb 3, 2018 · The different methods of temperature measurement are: 1. Mechanical. 2. Electrical. 1.Mechanical methods: Mercury in glass thermometers. This consists of a glass tube of very fine bore joined to a reservoir at the bottom and sealed at the top. A measured quantity of mercury is the enclosed.
Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
Temperature measurement methods and the types of temperature instruments, sensors, transmitters and devices used in the process industries.
There are four basic types of temperature measuring devices, each of which uses a different principle: 1) Mechanical (liquid-in-glass thermometers, bimetallic strips, bulb & capillary, pressure type etc.)
