Thermometers, infrared pyrometers

Pyrometer - a convenient temperature meter

A pyrometer is a device that allows precise temperature measurement without the need to approach the heat source. It is an excellent alternative to regular thermometers.

How does a pyrometer work? Every body at a high temperature emits infrared radiation. A pyrometer uses this physical phenomenon and measures the wavelength of infrared radiation emitted by a given body. It then converts it into temperature.

Pyrometers are often used in the production of plastics and in the metallurgical industry. They are also used in medicine, the food industry, during repairs of air conditioning and ventilation systems. They allow monitoring the condition of air conditioning and heating systems. In turn, in construction, pyrometers allow locating damp walls and ceilings, and are also used to detect drafts and thermal currents.

A huge advantage of pyrometers is their safety of use. During measurement, direct contact with a heated object is unnecessary - the laser sight allows you to obtain the necessary information without having to approach the heat source. With the help of a pyrometer, temperature measurement is very fast and convenient. The devices are also suitable for hard-to-reach places.

Types of pyrometers for non-contact temperature measurement

Pyrometers can be divided into three groups. The first one consists of broadband models. It is perfect for precise temperature measurement performed from a distance. Unfortunately, they are quite sensitive to water vapor and dust - in such conditions the readings may not be correct.

Optical pyrometers allow not only for temperature readings, but also for obtaining an image of heat rays. Nowadays, however, optical pyrometers are being replaced by digital models. Such devices measure temperature automatically, and you don't need any special skills to use them. They are equipped with a screen that shows an image of the object with superimposed rays. The device is precise, has a wide range of applications, and is convenient to use.

How to choose a pyrometer?

When buying a pyrometer, check the measurement range . It depends on the wavelength that the detector is able to capture. For basic applications, a pyrometer that gives a reading in the range of 0 to 50 degrees Celsius will be enough.

An important issue is what materials you intend to use the device for. Not every pyrometer can measure the temperature of transparent objects.

Be sure to pay attention to the emissivity coefficient. This parameter affects the accuracy of the measurement. Simple pyrometers have an emissivity coefficient set to a fixed value of 0.95. Materials with low emissivity such as metallic, polished or painted surfaces require the use of pyrometers with an adjustable emissivity coefficient.
