Meteorology is the study of the atmosphere and weather phenomena. Aristotle wrote one of the earliest works on meteorology in 340 BC called "Meteorologica" which described the science of earth's geology, elements, hydrology, seas, wind and weather. Key early weather instruments included the water thermometer in the 1500s, the mercury barometer invented in 1643, and the anemometer first described in 1450 which measures wind speed and pressure. Modern meteorology aims to understand atmospheric dynamics and forecast weather events like hurricanes and thunderstorms.

Bimetallic thermometer
Bimetallic thermometers use the different rates of thermal expansion in two bonded metals to measure temperature. They consist of a bimetallic strip formed into a spiral or helix with the metals joined at one end. As temperature changes, the free end of the strip expands or contracts differently between the metals, causing it to deflect. This movement is used to drive a pointer indicating the temperature reading. While simple and inexpensive, bimetallic thermometers have limited accuracy but remain useful for industrial processes where manual temperature monitoring is sufficient.

Limitations include needing cold junction compensation and signal amplification. Applications include temperature monitoring in steel making and heating appliances.
Thermometer and Its Types
There are several types of thermometers described in the document. Mercury thermometers measure temperature by the expansion and contraction of mercury when exposed to heat and cold. They are being phased out due to the hazards of mercury. Digital thermometers use an electronic sensor and LCD display, avoiding mercury. Other types include ear, infrared, and forehead temperature indicators. Proper use involves cleaning, placement in the mouth, rectum, armpit or forehead, and reading the temperature display. [/SUMMARY]
Rtd and thermocouples
RTDs measure temperature by detecting changes in electrical resistance of a wire as temperature varies. There are two types based on whether resistance increases or decreases with temperature. RTDs are used in bridge circuits where changes in resistance produce voltage changes proportional to temperature. Thermocouples use the Seebeck effect where different metals produce voltage when joined and subjected to a temperature gradient. Common types include J, K, B, S, T, and R which vary in sensitivity and measurable temperature range. Both RTDs and thermocouples require signal conditioning due to their small voltage outputs and are calibrated using a temperature indicator, controller, and oven.
Temperature measurement ppt
Temperature measurement is important across many industries and applications. There are several common temperature sensors including glass thermometers, bi-metallic thermometers, RTDs, thermocouples, thermistors, and IC sensors. Each sensor has advantages and disadvantages regarding factors like accuracy, sensitivity, temperature range, cost, and stability over time that must be considered when choosing a sensor for a particular application like industrial processes, manufacturing, health and safety applications.
