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?”
Ultrasound and infrared technologies are a perfect match when conducting inspections of switchgear over 1000 volts. At this voltage class and higher, thermal anomalies as well as corona and tracking conditions can occur, all of which threaten the reliability of the equipment being inspected.
For decades, temperature measurement has been used to gauge the operating condition of electrical components. With this Tip, we explore an alternative to the traditional Delta T method of prioritizing exceptions during infrared inspections of electrical distribution systems.
Sparta, NJ (June 28, 2013) – Mr. Ron Dech of Castle Air Conditioning & Heating Co., Easton, Pennsylvania, was recently named winner of Testo's $6,000 "Ultimate Contractor Collection Giveaway".
As the worldwide web has matured, websites have become a business necessity filling a key role in the marketing, promotion, and sales of many companies. In addition to direct sales, websites can generate additional revenue through a concept known as affiliate marketing.
According to the laws of physics, only a perfect blackbody may have Emittance of 1.0. Although the E value of real objects must be less than 1.0, some radiometers allow entry of E values exceeding 1.0
For years, many thermographers have sought to qualify the severity of detected exceptions by measuring temperature rise. Although this technique is widely practiced, failure to understand key issues can lead to misdiagnoses and unplanned downtime.
As infrared technology has advanced, radiometers have become a common tool for many maintenance technicians and mechanics. Although radiometers are relatively easy to use, there are several important factors that influence the accuracy of a radiometer’s readings.
While many infrared applications have been developed over the years, infrared roof moisture surveying remains one of the most difficult for thermographers to understand. This is due in large part to the fact that there are so many different roofs; roofs types, roof waterproofing, roof insulations, roof substrates, and roof decks.
With the onset of warm weather, tornado season has arrived. In an average year, tornadoes in the US cause 80 fatalities and 1500 injuries. Knowing what to do before and during a tornado is crucial for survival.
As part of their infrared inspection reports, thermographers frequently include exception diagnoses along with recommendations for repair. In this Tip, we offer our suggestion for the only recommendation a thermographer will ever need.
When performing infrared inspections of branch circuit panels, lighting circuits will often appear warmer than adjacent circuits. If adjacent circuits are lightly loaded, the warmer circuits may be indicative of a normal condition or they may represent a more serious condition.
An age-old challenge for thermographers is the ability to annotate or mark objects to make them easier to identify in recorded imagery. One possible solution is to mark targets with an ink pen with low emittance ink.
Infrared technology is an excellent tool to map the distribution of trapped water in insulated flat roof systems. In most cases, it provides 100% inspection coverage of the roof surface and often allows an experienced thermographer the ability to trace roof leaks back to their source.
The ever-increasing awareness of thermography causes many to consider offering infrared inspection services through new or existing business ventures.
Process furnaces or heaters are a critical component found in many petrochemical refineries. Performed properly, infrared inspections of furnace tubes can provide valuable data regarding tube condition and operating temperature.
Did you know that an automobile can be used to gauge solar loading? Under the correct conditions, a parked car can serve as a cheap, but effective, pyranometer.
The perpetual question among those using radiometric equipment is, “What emittance value should I use?” In this Tip, we address several options for providing emittance values.
Bradenton, FL—April 3, 2013—IRISS, a leader in the industrial infrared (IR) window market for electrical safety, announced today their new global headquarters officially opened.
There are those who assume that preventive motor maintenance is the best protective strategy for preventing motor failure and costly downtime.
