“…Detectors that are built into cameras as measurement transducers determine their further division. It should be noted that bolometric cameras are most often used due to the widest range of recorded infrared wavelengths [6,18]. These types of cameras are used in construction, the power industry or testing machines, and internal combustion engines, as presented in [16,19].…”

The article presents the results of thermovision tests of the disc brake and the drive system components located in its vicinity on the 111Ed electric locomotive in field conditions. For the mentioned vehicle, the research methodology was developed and the temperature distribution of the brake disc and components and assemblies located in its vicinity during braking was measured. In the article, special attention was paid to the configuration of the thermal imaging camera to the real conditions occurring during the test. This is important because due to the rotating brake disc, it is difficult to verify the temperature value with another contact measuring device. In exceptional situations, temperature measurement using thermocouples is used, but it requires an extensive additional measurement system and signal recording, which is more expensive. Although the thermal imaging camera measures the temperature indirectly, the correct configuration of the camera settings to the real conditions may affect the measurement error by several percent.

“…The use of thermography to diagnose the welding process and to estimate the quality of these connections have also been mentioned [10,11]. Secondly, thermography is used in the widely understood diagnostics of machines and their components, such as CNC machine tools [12], through mechanical spreaders [13], rotating machines [14], belt conveyors [15], internal combustion engines (catalytic reactors) [16,17], bearings (temperature measurement of moving rolling elements, and one must keep in mind that baskets in bearings may be measured only with contactless methods) and bearing nodes [18,19], brakes [20], as well as electrical devices and machines [21][22][23].…”

When the briquetting process of fine-grained material takes place in the roller press unit, the pressure reached is over a hundred megapascals. This parameter is a result, among other factors, of the geometry of a compaction unit and also the properties of the consolidated material. The pressure of the unit is not constant and the changes in value depend on a given place on the molding surface. By the process of generating different types of pressure on the surface of briquettes, their compaction is different as well. The distribution of temperature on the surface of the briquettes may determine the pressure used locally on them. Nevertheless, the distribution of stress in the briquetting material is still a subject of scientific study. However, it is known that the pressure exerted on the briquette is different for different compaction systems. The article includes authors’ further thermography studies on the classical pillow-shaped briquetting process (instead of the saddle-shaped ones that were previously conducted) of four materials (calcium hydroxide and water mixture, mill scale, charcoal fines and starch mixture, as well as a mixture of EAFD, scale, fine coke breeze, molasses, and calcium hydroxide). Immediately after the briquettes left the compaction zone, thermal images were taken of them, as well as forming rollers. Thermograms that were obtained and the variability of temperature at characteristic points of the surface of pillow-shaped briquettes were analyzed. They showed differences in temperature on the surface of briquettes. In all four cases, the highest briquette temperatures were recorded in their upper part, which proves their better densification in this part. The temperature differences between the lower and upper part of the briquettes ranged from 1.8 to 9.7 °C, depending on the mixture.

The analysis of thermal state of catalytic converter depending on fuel supply and engine load using thermo-vision

et al. 2017

The paper discusses the problem of thermal state of three-way catalytic converter depending on engine load with spark ignition fueled with gasoline and natural gas. The measurements on the test bench were performed, during which the temperature of the exhaust gases in the exhaust system was measured with the help of thermocouples, and at the same time, the track of the thermal state of the catalytic converter was monitored using thermo-vision camera. The stable work of engine with different rotation speed and values of load was considered together with transient states. The results of the measurements were presented in forms of charts and selected thermograms, qualitatively presenting the issue of thermal state of the catalytic converter.
