In different spheres of human activities are often required to determine the temperature of an object (subject, body). Of course, you can use a thermometer, but to meet today’s challenges, they were not enough. And here come to the fore pyrometers (thermometers), has great potential. They have an attractive design, have a compact size and easy to operate. Their convenience lies in the fact that the temperature measurement is done contactless by remote control.
Pyrometers are characterized by reliability and are resistant to physical impacts. With their help you can easily and quickly obtain the necessary temperature data.
Focal length
The conical beamwidth for many pyrometers can be at a sufficiently large distance, but up close it has a more complex form. Quite often, the instrument sensitivity will decrease to minimum diameter and then begin to expand in the form of a cone. Focal length is the distance where the minimum diameter is achieved. In the technical documentation for measuring devices with a similar radiation pattern this option must be indicated.
Manufacturers produced special-class short-throw pyrometers, the focus of which is in the range of 30 – 60 cm, spot diameter 5 – 8 mm.
The measuring device is equipped with short throw lenses give you the option to record the temperature of extremely small objects (the diameter can be 2.2 mm). As example, elements of electronic circuits. Therefore, short-focus pyrometer for electronics is the best device to measure the temperature in this region.
In addition, devices with short throw lenses can control the temperature close to
- With metal surfaces;
- to the painted surfaces;
- anodized metal.
