Using IR Inspections to Help Prepare for Heating Season

Mon, 10/26/2020 - 13:56
For many facilities the beginning of autumn means that heating season is just around the corner. Infrared inspections can help point out the types of energy liabilities that can account for significant waste.

Why Building Corners Appear Cool

Mon, 10/19/2020 - 13:56
When performing infrared inspections of framed buildings from the interior, thermographers often note that corners appear at a different temperature. With this Tip we explore the reasons for this condition and how to differentiate potential problems from normal conditions.

IR Inspections During Motor Rebuilding

Mon, 10/12/2020 - 13:56
Thermography can be a valuable tool for testing and monitoring in-service motors. It can also be a useful tool for detecting hidden problems within motors that are being rebuilt.

Autumn is the Time for Steam Trap Testing

Mon, 10/05/2020 - 13:56
With the onset of seasonably cooler weather, autumn is the time to prepare your steam system for the upcoming heating season. Testing your steam traps before the season begins can help to pinpoint costly leaks before the heating season begins.

Why Imagers and Radiometers Disagree

Mon, 09/28/2020 - 13:56
As the awareness of non-contact temperature measurement has increased, spot radiometers have become common tools in the workplace. Discrepancies frequently arise when temperatures taken with spot radiometers are compared to temperatures obtained with an imaging radiometer.

Making Your Own Blackbody Simulator

Mon, 09/21/2020 - 13:56
Blackbody simulators are essential tools for checking the calibration of infrared imagers and radiometers. One alternative to purchasing a blackbody simulator is to make your own.

Standards for Infrared Thermography

Mon, 09/14/2020 - 13:56
As thermography has matured, standards have appeared governing the conduct of infrared inspections and the proper use of infrared test equipment. With this Tip, we examine the importance of standards to practicing thermographers.

Infrared Inspections of Arc Fault Circuit Interrupters

Mon, 09/07/2020 - 13:56
Excess heating is often a sure sign of defective electrical equipment; however, the absence of heat can also be a sign of component failure. In this Tip, we demonstrate how thermal imaging may be used to detect defective Arc Fault Circuit Interrupters.

Art to Science: Changing Infrared 180 Degrees

Tue, 09/01/2020 - 13:56
Infrared (IR) thermometry has been used for forty years to monitor tube metal temperatures in refining and chemical furnaces. The application of IR thermometry has often been characterized as highly operator dependent and therefore developed a very poor reputation in the industry from poorly applied and interpreted results.

How Much Certification Do You Need?

Mon, 08/24/2020 - 13:56
Certification and levels thereof are one of the most frequently discussed issues in thermography. With few standards addressing certification, purchasers of infrared inspection services and thermographers often ask, “How much certification is necessary?”

Temperature Limits for Drive Belts

Mon, 08/17/2020 - 13:56
Temperature is frequently used to gauge the condition of motors and power transmission equipment. In this Tip, we discuss the effect of heat on flexible drive belts and temperature limits for them.

The Problem with Solar Loading

Mon, 08/10/2020 - 13:56
Everyone who has performed infrared inspections outdoors on sunny days is familiar with the problem of solar reflections. Compensating for solar reflections is usually accomplished by repositioning the thermal imager to change the viewing angle to eliminate the reflection. For objects exposed to strong sunlight, a more insidious problem can occur in the form of solar loading.

IR Inspections of Smooth Surfaced Roofs

Mon, 08/03/2020 - 13:56
Having the right tool for the job is often essential for success. When performing infrared inspections of smooth-surfaced roofs, a short wave thermal imager can significantly outperform a long wave imager.

New Software is Revolutionizing Thermography

Mon, 08/03/2020 - 13:56
Infrared thermography has become a popular tool for a wide range of applications. Worldwide, thermography is used on a daily basis to detect and document thermal patterns associated with defects in electrical and mechanical systems, building envelopes, and commercial roofing systems.

Inspecting Service Entrance Cables

Mon, 07/27/2020 - 13:56
When performing infrared inspections of electrical systems, many thermographers tend to focus their attention on outdoor substations and overhead electric lines. Unexpected failures can occur when service entrance cables are overlooked.

Heat Stress and the Human Body

Mon, 07/20/2020 - 13:56
For many, the peak of Summer brings high temperatures to the workplace. For others, high temperatures in the workplace are an everyday occurrence. Understanding heat stress and its attendant safety challenges is crucial for those working in hot environments.

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.
