Wed, 11/15/2017 - 13:52
West Windsor, NJ November 15, 2017 – Twelve men and women from across the US recently completed the Level I Infraspection Institute Certified Infrared Thermographer®training course.

Checking IR Equipment Calibration

Sun, 11/12/2017 - 07:35
Equipment calibration can have a significant impact on the accuracy of infrared temperature measurement. In this Tip we discuss a simple technique for checking the accuracy of imaging and non-imaging radiometers.

Does Thermography Really Save Time and Money?

Sun, 11/05/2017 - 08:05
“Thermography saves time and money” is a statement frequently associated with thermal imaging. In this Tip, we discuss the accuracy of this popular claim.

Note These Causes of Motor Failure

Brushing up on Important Root Causes Now can Prevent Headaches Later.

Easier Than A, B, C

Sun, 10/29/2017 - 08:51
When performing infrared inspections of electrical distribution systems, many people identify the individual phases of polyphase circuits as A, B, and C; others frequently use 1, 2, and 3.

An Emittance Greater Than 1.0 ?

Mon, 10/23/2017 - 06:25
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. The following describes how these radiometers achieve the impossible.

IR Imaging for Checking Tank Levels

Sun, 10/15/2017 - 15:06
For many facilities, obtaining accurate product level information for tanks and silos is critical for effective inventory management and safety. Under the right conditions, a thermal imager can quickly indicate product levels and serve as a cross reference for calibrating level indicators.

Using a Blower Door During an IR Inspection

Sun, 10/08/2017 - 11:29
Data obtained during infrared inspections can often be improved by incorporating other tools. When it comes to building inspections, a blower door can be useful in detecting air leakage sites and helping to gauge the airtightness of a building.

Non-Destructive Testing of Steam Traps

Wed, 10/04/2017 - 11:46
With green awareness at an all-time high, facility managers are constantly on the lookout for new ways to save money and energy while reducing their company’s carbon footprint.

Calculating the Value of an Electrical Hotspot

Sun, 10/01/2017 - 05:15
What is the financial liability of a hotspot within an electrical system? Probably less than you think since electrical hotspots waste surprisingly little energy even when operating at high temperatures.

The Myth Behind IFOV Values

Mon, 09/25/2017 - 03:53
A specification commonly provided for thermal imagers is Instantaneous Field of View or IFOV. Many people mistakenly believe that IFOV values provide meaningful information about a thermal imager’s performance.

Change Routes with the Season

Mon, 09/18/2017 - 11:29
Traditionally, many facilities perform infrared inspections on an annual basis. While this approach may detect deficiencies within operating systems, systems not under load due to seasonal or operational conditions cannot be effectively inspected.

Point Radiometers & Spot Measurement Size

Sun, 09/10/2017 - 06:39
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.

Infrared Inspections of Lightning Arrestors

Sun, 09/03/2017 - 07:21
Infrared thermography is a proven technology for detecting defects in electrical circuits that are under load. Thermal imaging can also be used to detect defective lightning arrestors that are leaking current to ground.

Are Electrical Switchgear Surveys Still the “Low-Hanging Fruit” of Infrared Thermography?

Fri, 09/01/2017 - 11:58
This paper discusses the market forces, insurance requirements, government regulations and risk management thinking that are changing the electrical testing industry in general, and the electrical infrared testing application in particular.

School’s Open – Drive Carefully

Mon, 08/28/2017 - 12:00
By early September, over 55 million children across the United States will head back to school.

Blinded by the Light

Mon, 08/21/2017 - 11:36
While it is often interesting to use a thermal imager to view ordinary objects, imaging the sun, arc welders and similarly hot objects should be avoided unless your imager has been built specifically for these applications.
