Infrared Thermography Technologies for Thermal Measurement & Control of HMA Pavement Construction

Partial Abstract

Airfield Highway 2015 CD_front.inddArticle By: Robert L. Schmitt1; Tyler T. LeClair2; and James O. Hedderich3

Infrared thermography technologies are rapidly developing for thermal measurement and control of hot mix asphalt (HMA) pavement and airfield construction.

Two technologies currently used and/or specified include hand-held thermal imaging cameras for discrete measurement and paver-mounted temperature sensors for continuous measurement.

A field evaluation of these new technologies was conducted on three asphalt paving projects by collecting thermal readings in the truck box, paver hopper, and behind the paver screed…

Online — This applications story looks at the use of thermal imaging as a method to expedite identification of faulty Photovoltaic (PV) solar cells, especially in solar generation panels and “farms”.

Solar cell power generation systems use a collection of PV panels to convert sunlight into electrical energy using the photoelectric effect. Each panel is made up of several PV modules, each in turn consisting of a matrix of PV cells that convert solar radiation into electricity.

The failure of any PV cell may lead to a drop in power generation causing output yield losses. Continue reading

Wildlife surveys with Infrared Thermomraphy

North Birch Creek Sage Grouse Lek Survey

Online — The World War II era was the last time several sage-grouse leks were surveyed in eastern Oregon until this year when biologists tested using infrared (IR) technology to detect birds from the air.

Many other leks hadn’t been surveyed in more than 20 years. This video shows IR technology.

Measuring Brake Temperatures

By presse@micro-epsilon.de (Valentina Nikiforova)

NLDE1203-App-IR-highOnline — High-Octane Motorsport e.V., the motorsport association of Erlangen-Nürnberg University, uses Micro-Epsilon sensors for its racing car.

To improve the braking system, the company uses an infrared temperature sensor that measures the brake disc temperature using non-contact methods.

Brake disc temperatures are recorded during test drives in order to gather information about how the design of the brake disc can be optimized Continue reading

Introduction:

When performing high accuracy radiation thermometry, the size-of-source effect (SSE) of a filter radiometer can provide a significant contribution to the uncertainties associated with the measurements.

During the development of a new filter radiometer, the THermodynamic Optical Radiometer (THOR), which we designed specifically to measure the melting points of High Temperature Fixed Point (HTFP) cells, indirect SSE measurements were performed on a prototype instrument to aid selection of optical components and their optimum positions with the aim of minimising its SSE.

We performed tests to choose the objective lens, and to understand the effects of the collimating lens.
