TYPES OF THERMOMETERS AND THEIR USES.

TYPES OF THERMOMETER

A THERMOMETER  may be a device that measures Temperature or a gradient.

A thermometer has two important elements.

1.         A Temperature sensor (e.g the bulb of mercury in glass thermometer or the digital Sensor in an infrared thermometer). In which some change occurs with a change in  Temperature.

2.         Some means of converting the change into a numeric value, for e.g the visible.Scale that is marked on mercury in glass thermometer or digital read out on in

            Informal model. Thermometer are widely used in technology and industry to monitor processes in meteorology in medicine and scientific research.

There are many alternative forms of measuring device obtainable in today’s market:

Before you make your purchase, it is vital that you are made aware of the range of products available to you.

You should additionally perceive and take into account every style of thermometers, suitability for various different uses.

So, now  will tell all about the different types of thermometer and their uses.

You can find different methods of thermometer classification.  Decided to go with the principle of operation as a defining characteristic.

Therefore there are half-dozen quite thermometer base on however they work, here we will discuss one by one.

1.       Here is liquid in gas thermometer:

This type is oldest and most common kind of thermometer. It is used almost everywhere,

and its principle of operation is very simple.
This thermometer consists of a glass bulb and stem filled with a working liquid (alcohol or mercury) and an inert gas.
When the temperature changes the liquid expend or shrinks, when paired with a temperature scale.it is possible to use this occurrence to determine the temperature.

2.         Here is Manometer thermometer

 This type is also known as a pressure filled or vapor-pressure thermometer.

It determines the temperature base on the modification of Monomer thermometers can fill with a gas such as nitrogen, condensation such as alcohol, chloro methane, diethyl or mercury.

3.         Here is Gas Thermometer

1.         A gas thermometer determines the temperature base on the difference in pressure or volume of gas it is fill with.
There are constant pressure and constant volume of gas thermometer. The latter is more commonly used.

2.         Gas thermometer can be filled with any gas –but most popular option is hydrogen.
This types work best with very low temperatures.

4.         Here is Bimetallic thermometer

This is a mechanic Thermometer that works with a bimetal strip.

Bimetal means that it is made of two metals.
1          The strip is sensitive to the change in temperature and it causes

 mechanical displacement, which is used to determine the temperature.
2          These thermometer are perfect for higher temperature, as they become less

sensitive and accurate at lower temperatures.

They can be found in several family, marine industries, industrial industries etc.

5.         Here is Infrared Thermometer.

An infrared Thermometer that offers temperature from a little of the thermal radiation someday ,call black body radiation emitted by the object being measured.

1.        They are sometimes called laser a thermometer as a laser used to help aim the

            thermometer.
2.        Or non-contact thermometers or temperature gun, to describe the device’s ability

            to measure temperature from a distance.
3.         By knowing the amount of the infrared energy emitted by the object and its emissivity

            the object and it emissivity the object’s temperature can often be determined

within a certain range of its actual temperature. 4. An infrared thermometer is a subset of devices as thermal radiation thermometers.

6.         Here is Digital Thermometer

1.         Digital or electronic thermometers are one of the most recent development

            in thermometer field.

2          Instead of using liquid or gas pairs with a temperature scale. They have a

digital screen, which can show you the reading in mare seconds.
3          A digital thermometer has a thermistor that reacts to the change in

temperature and projects the result on the thermometer screen.

7.         Here is Clinical Thermometer.

1.         A medical thermometer (also called clinical thermometer) is used for measuring

human or animal body temperature.
2.         There are three most common clinical the thermometer used in hospital and

homes

a.         Mercury filled thermometers: one of the oldest type’s mercury, filled

            thermometer are slowly disappearing from most countries

In addition to not being the most accurate they might be very dangerous if broken, the mercury inside is toxic to people and the environment.

b.         Alcohol filled thermometer: alcohol filled thermometers, a safer alternative to the previous type, these thermometers use colored alcohol that expands to increased temperature, however both of these liquid filled

thermometer need your time to point out the temperature, if you want more results consider on of the following options.

c.         Digital thermometer: digital thermometer are quickly replacing all of the

            old liquid in glass versions.

They are quick, correct and convenient with to assist of oral, body part and cavity digital thermometers, you'll get your lead to mere moments.
