Measuring Brake Temperatures

By (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

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.

FLIR A655sc thermal imaging camera success story

Thermal Imaging Assists USDA Water Management Program

Thermal Imaging Assists USDA Water Management

FLIR 655sc Assists USDA Water Management

Meer, Belgium — FLIR Systems has published a new application story that describes how the FLIR A655sc thermal imaging camera now provides an indispensable means of data collection to the USDA Water Management research program.

At the US Department of Agriculture (USDA), researchers are looking into ways for farmers to be more productive by using less water. They do this, among other things, by deliberately imposing stress on crops and monitoring the water stress.

The most established method for detecting crop water stress remotely is through the measurement of a crop’s surface or canopy temperature.

As the crop becomes water stressed, the leaves will start to curl and transpiration will decrease leading to an increase in leaf temperature. Continue reading

Infrared Optics Handling and Cleaning

Recommended Practice for Both Uncoated & Coated Materials

Screen Shot_Janos_LensesOnline  —  The Janos Technology website contains some very useful information about Infrared Optics.

Perhaps one of the most practical items is their webpage on handling and cleaning Infrared optics. We think it is very good!

“Optics can be easily damaged or contaminated from poor handling and incorrect cleaning methods.

Be sure to consider the following guidelines:” Continue reading

IR Temp Measurement in Plastics Thermoforming

With the Calex PyroMini


PyroMini with optional touch screen interface

Leighton Buzzard,UK — The process of thermoforming a plastic sheet depends critically upon temperature.

Calex pyrometers have been used by leading manufacturers to control heating and cooling in thermoforming for more than 10 years, resulting in increased product quality, consistency and production rates, and a reduction in heating costs.


Forming temperatures typically range from 120 °C to 370 °C. Precise temperature control is required, and the high-performance PyroMini infrared temperature sensor is ideal. Continue reading

Pilkington Float Glass Process

An Industrial Application for Infrared Thermometers & Imagers

The Pilkington Float Glass Process, with more than 170 plants worldwide today, uses many infrared Radiation Thermometers and, in some cases, Thermal Imagers for process monitoring and control.

The process was developed by the Pilkingon Brothers Ltd. organization in St Helens, Lancashire, UK.

In the 1970s they, in turn, contracted with Land Pyrometers Ltd. (now Land Instruments International Ltd.), in neighboring Sheffield,Yorkshire, UK, to provide specialized single spot radiation thermometers for some of the process’s unique measurements in the “Tin Bath” and Annealing Lehr.
