What Are Pyrometers? Types, Advantages, & Applications

The coldness or hotness of any substance or object is a physical quality referred to as “temperature”. According to requirements, it can be measured in different scales and units. By using various devices and methods, any material’s temperature can be measured. To measure a substance’s or physical property’s energy level, different temperature measuring devices are utilized.

According to a material’s physical property, measurements of temperature can be determined by using the following:

Pyrometers
Infrared thermometers
Pressure gas thermometers
Constant volume gas
Bulb and capillary devices
Bimetallic devices
Silicon diodes
Thermocouple
Radiation thermometers
Electric resistance thermometers
Basic thermometers and more

Measurements can include Fahrenheit (F), Celsius (C), or Kelvin (or “k”, for an SI unit of temperature).

Pyrometer Types

There are two types of classifications of Pyrometers used to detect various objects’ temperatures. They are as follows:

Infrared/Radiation Pyrometer: Used in the infrared region to determine thermal radiation. It measures a targeted object’s temperature from the emitted radiation.
Optical Pyrometer: Utilized for detecting the thermal radiation of the visible spectrum.

Disadvantages and Advantages

There are disadvantages and advantages to using Pyrometers, which are frequently compared with thermometers. The following are advantages:

At variable distances, the temperature of different kinds of objects can be measured.
While measuring an object’s temperature, they offer good stability.
Fast response time.
Without coming into contact with the object, its temperature can be measured. This is referred to as “non-contact measurement”.

Then again, there are a couple of disadvantages to using Pyrometers which are as follows:

Due to various conditions – think thermal radiation, smoke, and dust – the device’s accuracy can be affected.
Though generally rugged, Pyrometers tend to be expensive.

Applications for Pyrometers

Various applications can benefit from the use of Pyrometers including the following:

Furnace temperatures can be measured
The temperature of highly heated materials and liquid metals can be measured
They can measure steam temperature for steam boilers
To determine the heat at the top of a balloon, they can be used for hot air balloons
For smelting industries
For metallurgy industries
From a greater space, they can measure the temperature of constant or moving objects

Pyrometers Versus Thermometer – What’s the Difference?

If you’re unfamiliar with a Pyrometer, you may wonder what the difference is between it and a thermometer. Here are the basics:

A Pyrometer measures high temperatures as a non-contact, remote sensing thermometer
A thermometer is a contact measurement device used for measuring temperatures
