The closest example from everyday life and also a great opportunity to understand how a strain gauge actually works. The strain gauge in an electronic scale is usually attached to the scale platform or support structure. When a mass is placed on the scale, the platform is deformed and the strain gauge is stretched or crushed, so to speak. This process changes the length or resistance of the strain gauge. This in turn affects its electrical properties, for example, changing the electrical resistance of the strain gauge wire.  <\/li>\n<\/ul>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-3c929c1\" data-id=\"3c929c1\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-2123ee3 elementor-widget elementor-widget-image\" data-id=\"2123ee3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/botland.com.pl\/blog\/wp-content\/uploads\/2024\/03\/waga.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"waga\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NzY3NzgsInVybCI6Imh0dHBzOlwvXC9ib3RsYW5kLnN0b3JlXC9ibG9nXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDI0XC8wM1wvd2FnYS5wbmcifQ%3D%3D\" data-wpel-link=\"internal\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"537\" src=\"https:\/\/botland.store\/blog\/wp-content\/uploads\/2024\/03\/waga-1024x687.png\" class=\"attachment-large size-large wp-image-76778\" alt=\"\" srcset=\"https:\/\/botland.store\/blog\/wp-content\/uploads\/2024\/03\/waga-1024x687.png 1024w, https:\/\/botland.store\/blog\/wp-content\/uploads\/2024\/03\/waga-300x201.png 300w, https:\/\/botland.store\/blog\/wp-content\/uploads\/2024\/03\/waga-768x515.png 768w, https:\/\/botland.store\/blog\/wp-content\/uploads\/2024\/03\/waga.png 1126w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-c68b2b7 elementor-widget elementor-widget-text-editor\" data-id=\"c68b2b7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The electrical signal from a strain gauge used in this way is usually very small, so it requires amplification.

Unfortunately, factors such as temperature, vibration, humidity and structural deformations have a significant impact on the quality of measurement, so it is important to place the balance in the right conditions and perform regular calibrations. For this reason, keeping the scale in the bathroom, where there is moisture, steam and often high temperatures, is not the best idea.<\/p>\n<\/p>\n<ul style=\"font-size: 16px; background-color: #ffffff;\">\n<li style=\"font-size: 16px;\"><span style=\"font-weight: bolder;\">Construction<\/span>.

In the plastics industry, strain gauges control the pressure when plastics are injected into molds, ensuring accurate shape and quality of products. In the laboratory phase, strain gauges help in material strength testing, such as destructive testing and fatigue testing.

They are used in a wide range of applications, from measuring pressure in electronic scales to monitoring stress in structures. The more sensitive capacitive strain gauges are sometimes more complicated to use, but offer greater precision. Using optical phenomena based on light wavelengths due to strain, optical strain gauges are higher end &#8211; you&#8217;ll find them in electromagnetic environments and medical devices. In terms of construction, one encounters flexible and vibration-resistant polymer strain gauges, ceramic strain gauges resistant to high temperatures and aggressive chemical environments, or piezoelectric strain gauges ideal for vibration and shock measurements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Refinement of designs, attention to structural safety and room for DIY enthusiasts &#8211; all with a single sensor.
