The benefits of thermography for condition assessment of insulated roofs are well documented. Performed on a regular basis, infrared thermography can help to extend the overall life of a roofing system when utilized as part of a preventive maintenance program.
When it comes to spending year end budget monies, the phrase “Use it or Lose it” often applies. Training can be a wise choice for those looking to reduce a budget surplus.
Whether you are facing an equipment shortage or looking to evaluate the characteristics of a new imager prior to purchase, renting a thermal imager may provide a solution. As with purchasing an imager, there are several important things to consider when arranging for a rental unit.
Most modern thermal imagers have the ability to record time and date along with thermal images. Taking a moment to ensure that the correct time and date are displayed on your imager before you begin your inspection can help to avoid wasted time and the collection of inaccurate data.
Infrared thermography is a useful tool for detecting heat patterns caused by overloaded electrical circuits. In this Tip we discuss what constitutes an acceptable load.
Introduction to Radiometric Calibration of Thermal Imaging Cameras and Other Infrared Instrumentation
Infrared Calibration Equipment includes two key items: a Blackbody Radiation Source (BBR) and a Reference Thermometer. The Reference Thermometer can either be a Contact Probe or a Transfer Radiation Thermometer (TRT).
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
