What is Thermography?
Unlike our eyes a thermography camera works in the infrared part of the spectrum. Infrared energy is associated with heat, and all objects above absolute zero emit energy in this part of the spectrum. Hotter objects simply emit more energy than cold objects. A thermography camera is device that converts invisible infrared energy into a visible image. Most modern cameras can calculate the temperature of an object based on how much infrared energy it emits.
Although a thermography camera seems very simple, it is in fact a very complicated device. The image it produces includes the energy radiated from the object, but it also includes reflected energy, and in some cases, transmitted energy. So while producing images is in itself fairly straight forward, interpreting them can be difficult. For this reason, proper training and certification is essential. Temperature calculation is also subject to error by the thermographer, sometimes this can be very significant, and it is essential for thermographer’s to understand the potential mistakes.
Is Thermography Different Than Thermal Imaging?
Thermography and Thermal Imaging are essentially the same thing. The word comes from Thermo- meaning heat, and graphy- meaning vision. So Thermography, means seeing heat, which is the same as thermal imaging. Working with thermography involves using a thermal imaging camera. Other common names are infrared imaging, thermal scanning, thermographic surveys, infrared scanning and IR scanning.
Where is Thermography used?
Thermography is widely used in industry, and has been widely accepted by insurance companies as a way to reduce risk. Many objects are potential candidates for a thermography inspection. This includes electrical equipment, mechanical components, buildings, refractory lining, furnaces, even people.
Thermal Vision can help to assess the condition of your equipment, and deliver professional reports, with strong recommendations for corrective action. We have the expertise to take the images, write the reports and even follow-up with prognostics. Whatever your needs, Thermal Vision can help.
Thermal Vision employes thermographer’s trained and certified to the highest of standard in the UK or Ireland.
Thermal Vision was established in 1998 by Bob Berry. Bob has over fifteen years experience as a director of an electrical contracting company, where his varied responsibilities included site management, maintenance and testing. Among other things he was involved in the DSR certification of electrical installations for their hydrocarbon licenses, testing, and certification and commissioning of electrical installations.
We provide services in all applications worldwide. We can develop and monitor in-company thermography programs, supervise and mentor your thermographer’s and write your procedures and written practices.
Our experience in Infrared Thermography covers a very wide range of applications not only in electrical installations, but also other important areas like furnaces, reactors, buildings, pipelines, chimney stacks, bearings, steam lines, etc.
Our emphasis has always been on quality and flexibility, with reports available in a variety of formats, our standard package includes a hardcopy report and a softcopy contained on our unique customer utility CD, along with a secure online version. Our reports have been created with significant input from insurance companies, ensuring that everything conforms to the needs of a modern insurance company.
We provide three levels of service.
Value Package; this is intended for small facilities and includes a quick check, a limited number of images and a basic report.
Standard Package; this includes more detail, more images and recommendations etc. The report is guaranteed to be accepted by an insurance company.
Premium Package; this includes an unlimited number of images, a very detailed report, prioritisation of problems and a cost benefit analysis. Changes to the reports are also permitted, and it includes email and telephone support. The report is guaranteed to be accepted by an insurance company.
