The service life or life expectancy of an appliance describes the service life in operating hours. This is the period of time during the operation of an appliance until the first signs of wear (e.g. dried-out capacitors) occur. The component with the lowest life expectancy in an appliance determines the service life of the entire […]
The shock and vibration resistance(shock resistance) provides information about the robustness of the mechanical structure of a device. The methods for assessing shock resistance are defined in IEC 60068-2-27. The shock load capacity is important for the operating and transportation conditions of the devices. The methods for assessing vibration resistance are defined in IEC 60068-2-6 […]
In signal processing, information is extracted from pre-processed signals in order to draw the right conclusions based on this information. A distinction is made between analog and digital signal processing. Filters are common tools in both analog and digital signal processing. A signal is processed in such a way that unwanted signal components are filtered […]
Spotlights are suitable for illuminating small objects from a great distance with standard and high-power LEDsand for coupling into lens systems with a coaxial lighting connection. The light can be focused using an optical attachment(condenser lens or C-mount lens).
Structured lighting (see also direct incident light) is the projection of lines, grids, dots or circles onto an object. This allows three-dimensional characteristics of the object to be determined and measurements and presence checks to be carried out even when there is no brightness contrast. In addition to line projectors, lasers(laser triangulation) are often used […]
Telecentric illuminators (or collimated background or transmitted light illuminators or condenser illuminators or condensers) are optics whose light source (usually an LED) is projected to infinity, whereby a parallel beam path illuminates the object being measured. This results in improved edge detection in optical measurement technology and therefore greater measurement accuracy. Especially in combination with […]
The specific thermal conductivity or thermal conductivity coefficient λ of a material is a quantitative measure of its ability to conduct thermal energy. The unit for this is W / (m- K) (watts per meter and Kelvin). It describes how well or poorly a material conducts heat and how well or poorly it is therefore […]
Measure of the ability of a material to conduct thermal energy. See also thermal conductivity.
Also thermal expansion. The change in the geometric dimensions of a body caused by a change in its temperature. The coefficient of thermal expansion serves as the characteristic value. Thermal expansion leads to a change in the density of the body. In the case of fluids, this can also be accompanied by altered pressure ratios.
