With such a large range of pyrometers on the market all designed for optimal performance and accuracy, without guidance it can be so confusing to find the ideal solution. Our technical experts have put together a short guide to help you in your selection process.
1) What is the likely temperature range that you need a pyrometer to measure?
The fundamental role of a pyrometer is to measure temperature so asking this question could seem a little pointless but in order to choose the most accurate and appropriate pyrometer, it is essential to know the temperature range. Each model has a slightly different range of measurement so it is important to specify both your overall minimum and maximum temperature.
2) What is the material of the object being measured?
Again, knowing the material to be measured is crucial in choosing the right pyrometer – each model has a different spectral range (or wavelength) which needs to be matched to the material to be measured. There are pyrometers designed to measure metals, glass, wood, and inorganic materials to name just a few categories.
3) What size is the object and how far away will the object be?
The same matching process is necessary depending upon the size of the object and how far away it is from the pyrometer too. It is possible to select which optics the pyrometer has that will determine the field of view (FOV) and the size of the measurement spot. Providing the correct configuration for the intended application.
4) In what environment will it be used?
Understanding the working environment is really important too and there are a variety of factors that need to be considered. For a start, what is the ambient temperature and what is the atmosphere like? Elements such as steam, dust or smoke can affect certain pyrometers. Perhaps there is a viewing window and what material is that made of and could there be IR radiation present? All of these factors can affect the measurements which is why it is important to seek advice from one of our technical specialists to ensure you choose the right pyrometer.
5) What speed response rate do you need?
In certain applications, the temperature can change rapidly and a pyrometer but be able to reflect this with a fast response rate. Higher end pyrometers tend to have a faster response rate.
