What factors affect the emissivity of an object? Material Non-metals, usually have a high emissivity, and are usually fairly constant over time. Metals on the other hand can have a very low emissivity, and as they usually oxidise, their emissivity tends to vary drastically over time. Surface Polished and shiny surfaces tend to have lower … Read More
Why thermocouple readings don’t compare with camera results Question received by email, slightly edited; We are busy working with a foundry that mainly does High chrome white irons. The problem that we are encountering is that there seems to be a variance of about 80°C between our thermal camera and the thermocouple that they … Read More
I was asked about this earlier this week, so I dug up this video that I put together some time ago. It shows how to display two profile plots in the same window/tab when using Flir ResearchIR max.
Thanks to all for the positive feedback on my presentation at the ITC user conference held in Coventry on September 27th & 28th 2017. ITC did an amazing job at organising this years event, with attendance from over 30 countries. The event was a successful mix of presentations and practical workshops.
Thanks to all we met at Reliability Ireland 2017. It was good to catch up with so many in the industry, and to meet so many new people. A special thanks to the organisers (Tellabs) for organising such a great event, and to all those that attended our presentation.
All gases have different properties. Some gases certainly do emit infrared energy. However, they normally only emit in a very narrow spectral band. Thus seeing a gas is certainly possibly by using a camera adapted with a suitable spectral filter. Seeing the gases is not the same as measuring its temperature, and there are additional … Read More
