When it comes to the industrial world, measuring heat is key in targeting potential issues or the necessity of continued coolant. At Schreier Industrial, we understand the importance of thermography as a predictive technology in a broad range of manufacturing facilities’ maintenance programs.


Thermography as a predictive technology or simply as a way to measure hot spots in an indoor or outdoor environment has a much shorter history than the concept of heat differences. Thermal imaging can be traced as far back as the early 1800s. The infrared spectrum was a recent discovery, and engineers were beginning to create devices that could provide an image of infrared that could be seen by the human eye.


In 1835, a thermo-electrical device that could measure temperature variations throughout the human body was created. This device measured inflammation and fevers based on the average healthy level of 98.6º F (37º C).


By the early 1900s, the first thermal image cameras were developed almost at the same time as many other types of film cameras. These imaging systems were used extensively throughout both World Wars and quickly found their way across the Atlantic to be studied in the U.S.


In 1947, Texas Instruments and the U.S. military partnered to engineer an infrared line scanner. These cameras tracked heat signatures using photographs but weren’t able to record real-time temperatures. In fact, it took over an hour to generate one image, which was not ideal for the purposes of modern-day thermography. To create a more practical infrared camera, researchers across the world worked to develop cameras and thermal reading technology for the rest of the 20th century.


By the 1960s, thermal infrared imaging systems were applied in different industrial settings. The use of thermographic readers was applied to production systems, chemical results, and general systems monitoring. By the late 1990s, thermography diagnostic systems were widespread throughout the manufacturing world. Software programs, however, were still primitive compared to what’s available to our customers today.


Throughout the 2000s, digital thermography readers with highly intelligent software that runs diagnostics to the thousandth of a degree were developed. The exponential prevalence of wireless connections allowed the growth of advanced portable instruments with increased user-friendly applications. Complex programs were developed that broadened the analysis capabilities of thermographic software, and highly accurate projections were made more and more possible.


Thermography systems today are a vital component of the majority of industrial maintenance programs. To learn more about integrating thermography technologies into your facilities, contact Schreier Industrial today at (218) 402-0838 or info@schreierindustrial.com.
