IR Inspections for Sewer Systems

Mon, 07/13/2020 - 13:56
In regions with older infrastructure, sewer system integrity is often a primary concern. Under the right conditions, thermography can often detect sewer leaks or voids surrounding the system that can lead to sinkholes.

Preventing a Transformer Fireworks Display

Mon, 07/06/2020 - 13:56
Infrared inspections of oil filled transformers can help to increase reliability and extend transformer life. Detecting hotspots on the bushings of these transformers may also help to prevent a catastrophic explosion.

Visualizing Reflective Temperature on Electrical Equipment

Wed, 07/01/2020 - 13:56
In the field of IRT, we learn that Total Radiosity is a combination of Emissivity, Reflectivity, and Transmissivity (E+R+T=1). It is a concept that takes time to get your head around, but one that is essential to master on the road to becoming an effective thermographer.

Point Radiometers and Spot Measurement Size

Mon, 06/29/2020 - 13:56
With awareness of infrared technology at an all time high, point radiometers have become a common tool in many areas. Frequently, knowledge of proper operation lags behind instrument popularity. Understanding how spot measurement size affects accuracy is imperative to collecting meaningful data.

Building Envelope Inspections – Which Way Do We Go?

Mon, 06/22/2020 - 13:56
Infrared inspections of building envelopes have many uses. Of paramount importance is a logical inspection route that covers all subject areas and provides report data that can be easily followed.

Accuracy and Sensitivity - Part 2

Mon, 06/15/2020 - 13:56
Objective specifications are frequently used to describe the performance of thermal imaging systems. In part two of this Tip, we explore the significance of our second frequently misunderstood term, Accuracy.

Accuracy and Sensitivity - Part 1

Mon, 06/08/2020 - 13:56
Objective specifications are frequently used to describe the performance of thermal imaging systems. In this two-part Tip, we explore the significance of two commonly used, but frequently misunderstood terms: Accuracy and Sensitivity.

How to Calculate Emittance

Mon, 06/01/2020 - 13:56
Utilizing correct emittance values is imperative for accurate non-contact temperature measurements. Knowing how to accurately calculate emittance values can help to ensure the accuracy of infrared temperature measurements.

Infrared Body Temperature Screening – Know the Basics Before Starting

Mon, 06/01/2020 - 13:56
Many communicable diseases, including COVID-19, cause an increase in human body temperature. Based on this fact, one part of the Federal guideline “Opening Up America Again” requires businesses to perform temperature checks for workers, visitors, and guests.

The FLIR One Infrared Imaging Radiometer and Marine Surveying

Tue, 05/26/2020 - 16:31
In 2003 Jack started applying infrared thermal imaging to Marine Surveying using a FLIR model E2 imaging radiometer. While the imager measured temperature, it initially did not save images in a format that could be analyzed with post processing. Jack had the unit upgraded to save images in radiometric format.

Grilling Safety Tips

Mon, 05/25/2020 - 13:56
With Summer upon us, many will return to outdoor cooking on a regular basis. In this Tip we offer important safety considerations for all outdoor chefs.

Determining Maximum Operating Temperature for Motors

Mon, 05/18/2020 - 13:56
Operating temperature can have a significant impact on the service life of operating electric motors. Accurately determining maximum operating temperature for motors is critical for setting temperature limits.

Thermal Imagery to Detect Roof Fasteners

Mon, 05/11/2020 - 13:56
Thermal imaging is a proven technique for detecting latent moisture within low-slope roofing systems. Under the right conditions, thermal imaging may also indicate the number and location of roof fasteners.

The Power of Inductive Heating

Mon, 05/04/2020 - 13:56
The magnitude and intensity of inductive heating should not be underestimated when performing infrared inspections of electrical switchgear. Inductive heating is derived from the proximal interaction of non-current carrying devices with the magnetic field around energized conductors that are under load.

Tips to Keep Driver-Driven-Transmission Systems Up and Running

Fri, 05/01/2020 - 13:56
Power transfer from electric motors or engine-drive pulleys to driven shafts by way of chains and sprockets or v-belts is an application of legacy systems that are still very relevant in today’s plant.
