Thermal imaging is the capture and conversion of Infrared radiation (IR) to the visible spectrum. IR radiation is radiated (sent out from) all objects that have a temperature above 0 Kelvin (-273°C). This radiation will have a wavelength that is specific for its temperature and emittance. Emittance is the measure of an object to receive and emit IR measured between 0-1.
There are many misconceptions surrounding the use of thermal imaging due to the way it is has been displayed in movies, some of these misconceptions include:
There are two main ways in which thermal imaging is analysed, being either qualitative, or quantitative. Quantitative analysis is more complex as it involves finding the exact temperatures of components and requires the use of additional external consumables to modify the emissivity of an object and is not typically necessary. Qualitative analysis is more commonly used for thermal imaging as it requires less setup and no use of external consumables. Instead components temperatures are compared to similar components to find a thermal variance (temperature difference) between them. This will not find exact temperatures, however it allows for easy identification of hot spots which may indicate problems. Thermal Scanners typically offer qualitative analysis for all services, however if requested and agreed upon, a quantitative analysis can be completed at additional cost due to the higher level of training and consumables required.
Electrical Thermal Imaging
Electrical thermal imaging examines the operating temperatures of electrical equipment under normal load and detects potential problems before they develop, such as loose connections or degraded components.read more
PV Solar Panel Thermal Surveys
Thermal scanning can be completed upon active solar systems such as Photovoltaic panels or solar hot water systems to find defective cells and ensure normal operations after a large weather event such as a storm.read more
Cold Room Room Insulation Leakage
Thermal scanning can be utilised to examine the thermal loss of key infrastructure such as cold rooms and freezers, leading to a more energy efficient system in turn reducing power costs. This can be utilised on both existing systems and for quality assurance of new installations.read more
Thermal imaging can be useful for many different applications involving identification of heat energy. However most faults and problems involving thermal energy cannot be detected by the naked eye, Some of these problems can include:
Thermal imaging requires specialised training to be able to account for various phenomena that are encountered during thermal imaging surveys. All Thermal Scanners technicians have received specialised training in thermography. Some of the phenomena that must be accounted for include:
Thermal imaging is considered to be a non-destructive testing method, as it can be performed on operational components without damaging them. The benefits of this are two-fold, first enabling components to be examined / tested during normal operation conditions helps to highlight and show the normal operating temperatures. Second, thermal imaging does not require a costly shutdown to examine components. One key requirement of thermal imaging is that the examined equipment must be under normal load during inspection. The benefits of thermal imaging vary depending on the area it is utilised within, however share some key common factors:
Why would you obtain Thermal scanning? There are a variety of reasons that one may obtain thermal scanning these can include:
Protect Your Employees, Customers and Business!
Thermal screening is a rapid, non-invasive and cost efficient control measure that can help businesses to mitigate their risk on the work site. With the ongoing COVID-19 situation evolving, Australian businesses are having to implement risk mitigation and contingency measures to ensure staff safety, product hygiene and business continuance.
Our advanced infrared thermal imaging devices and experienced thermographers enable us to identify any personnel displaying an elevated surface temperature. These potentially at risk employees will be identified and screened in line with ISO/TR 13154:2017.
Please contact our office on 1300 309 562 to discuss your specific thermal screening requirements and how we can help protect your business, staff and customers during this time.
Note: We do not operate medical devices and they cannot detect COVID-19, however we can detect an elevated surface temperature which is symptomatic of a fever.
