Thanks Majed,
It looks like I looked too deep. The answer is not with Ohm's Law but in the power equation and perspective. The hot spot(high resistance short)is an unintentional load on the current loop that affects resistance and source current and therefor power measured at the source...
Anyone want to give a shot at explaining a common thermographic term in equation form? The term "hi-Resistance-Short" is used to describe a localized hot spot on electrical contacts/connections. Trying to explain this term litterally as a function of common electrical laws seems rough, or I...
Hi,
I recently worked out a problem for a client dealing with ir measurements of molten steel and determining when the pour goes to a slag state. The imaging equipment was protected from an environment more harsh than the one you describe and is working. You might contact Bill Barron Sr. of...
I have not seen a website that meets your request, but do know that Infraspection Institute completed two studies on misalignment of motor/load systems and documented their results pictorially. The most current study, completed for the Eli Lilly corp. shows motor/coupling/load ir images at...
in adition to irstuff's input you might go to http://www.measure.com/sensors/sensor-roomocc.html for a little more info.
There is a lot of info on the internet on the subject, but this site kept it short.
Motion detection often includes microwave detection systems. Higher order detection...
When deciding on your training, please consider Infraspection Institute. Shop around and talk to others.
Please remember that temperature measurement will be Level II thermography. Your Inframetrics/Flir Thermacam has an accuracy of +/- 2 degrees C or 2% (whichever is greater). Bear in mind...
Yes, flash thermography among others. The American Americas Cup vessels are one example of use of the questioned inspection capability. The vessels hull is fiberglass and water intrusion can slow or damage it. Key your internet queries on transmissive or front surface thermography/ir and...
To MWMONTY,
Great question! The responses generated are a learning experience! I thought I might have a bit of usefull info for you. In 1990 at IRINFO'90, Mr. Alan C. Pierce of Factory Mutual Research Corporation presented a paper on derating electrical and electrical/mechanical components...
Contact me at toadsack@arkansas.net for further contacts. What you are looking for is taught by some ir training groups and there are guidelines available through at least one. Also, a friend was responsible for the structural energy auditing program (using level I thermography)for Arkansas...
Might I suggest a different approach? Baseline energy requirements to produce your current output while tracking plant ambient tempreature and humidity inside to weather conditions outside. Use the ir equipment to identify candidates for insullation, insullating easiest and largest areas...
The spot radiometer (gun) that most use is typically quite accurate if:
1. The target size is smaller than the spot(typically written on the side of the gun as size to distance or in the literature- again size to distance.
2. The background is measured and and your gun is capable of having...
Sounds like a lot of trial and error ahead! As long as particulate solids are fine enough and dispersed enough, your imagers spot size will probably cause the imager to ignore this particulate to a large degree. Moisture in the air will possibly prove to be the second biggest annoyance...
Thermal Image is right on track. Several of my clients are water utilities and would give their left arm if ir could find leaks in small pipes not to mention the piping alone! Alot of work is being expended in developing a good ground system, it just has not come up yet. For the moment, local...
Your question about Accuracy when performing a Qualitative scan is answered by considering that you are using the same instrument to measure relative temperature differences within the same image background(in most cases). Two schools of provided comparison of like data are commonly used by...
