Fluke TiR32 Thermal Imager (Work in Progress)
T or infrared cameras are cameras that form anhermographic cameras
image using . IR cameras were originally developed forinfrared radiation
military use and have slowly migrated into other fields as varied as
medicine and archeology. In the building industry it has different usages,
for example we can use thermal cameras to detect leakage or thermal
bridges. You can use the the facultys TiR32 Thermal imager to analyze
the thermal radiance of any building, object or even people. The picture on
the right shows an interior corner in infrared as well as the device itself.
There is also a general overview here of the things you need to
understand prior to using a thermal imager in order to understand the
results.
The data can be stored either as a JPG file or as an IS2 file, which is the
equivalent of a RAW format on modern dSLR cameras. While the first
enables you to make fast files for presentation purposes, the latter can be
accessed with the free SmartView software and explored, either you goal
is to extract temperatures in exact positions or you need a report from a
set of images.

Pre-requisites, access and learning to use the Fluke TiR32
Thermal Imager
The TiR32 is fairly easy to use, but it is not a toy (i.e. it is also not cheap).
You can borrow it as long as you are a responsible person and need the
device for your studies. In this case you should study this page carefully,
going through all the videos and when you come to pick up the device for
the first time, you need to answer some questions to ensure that you are
familiar with the device and also show that you know how to use it. After
you have shown that you can use the device, you will receive booking
access for it in the equipment booking system. If a group wants to borrow
the device, one person still needs to be responsible for the device.
Health and Safety
Batteries contain hazardous chemicals that can cause burns or
explode. If exposure to chemicals occurs, clean with water and
get medical aid.

General Information
Infrared Photography
Infrared energy is just one part of the , whichelectromagnetic spectrum
includes radiation from , , , a thin region of gamma rays x-rays ultra violet visi
, , , , and . Theseble light infrared terahertz waves microwaves radio waves
are all related and have different length of wave. (a.k.a. wavelength). All
objects emit a certain amount of black body radiation because of
their temperatures and in accordance with it. Generally speaking, the
temperature has straight effect on its infrared radiation it means that the
infrared radiation increases by rising temperatures.
Emissivity
The of a material (usually written or ) is the relative ability ofemissivity e
its surface to emit energy by radiation. It is the ratio of energy radiated by
a particular material to energy radiated by a black body at the same
temperature. A true black body would have an = 1 while any real object
would have < 1. Since it is the ratio of tow numbers with similar
dimension, therefore it is a dimensionless quantity.
See emissivity information for actual temperatures. Reflective
objects result in lower than actual temperature measurements.
These objects pose a burn hazard.
Use the product only as specified, or the protection supplied by
the product can be compromised.

In general, black objects have more emissivity factor comparing to other
objects. In other words, the emissivity of duller and blacker materials is
closer to 1 and the more reflective a material is, the lower its emissivity.
Highly polished silver has an emissivity of about 0.02.
Thermographic Camera
A thermographic camera or infrared camera is a device that forms an
image using infrared radiation, similar to a common camera that forms an
image using visible light. Instead of the 450--750 nanometer range of the
visible light camera, infrared cameras operate in wavelengths as long as
14,000 nm (14 µm).
Application
Thermal imageing photography have many different usages. For
example, firefighters use it to see through smoke, find persons, and
localize hotspots of fires. With thermal imaging, power line maintenance
technicians detect overheating joints and parts, a telltale sign of their
failure, to eliminate potential hazards. Where thermal insulation becomes
faulty, building construction technicians can see heat leaks to improve the
efficiencies of cooling or heating air-conditioning. Thermal imaging
cameras are also installed in some luxury cars to aid the driver, the first
being the 2000 Cadillac DeVille. Some physiological activities, particularly
responses, in human beings and other warm-blooded animals can also be
monitored with thermographic imaging. Cooled infrared cameras can also
be found at most major astronomy research telescopes.

purposes. Fluke TiR32, is a thermal camera which is optimized for building
envelope inspections and building diagnostics.

Uncooled infrared camera
There are two types of infrared camera, cooled and uncooled. Fluke TiR32
is the uncooled camera. This kind of camera use a sensor which is
operating at normal temperature, or a sensor stabilized at a temperature
close to ambient using small temperature control elements. All of the
modern un-cooled detectors use sensors that work in according with the
change of , or . In order to reduce image noise,resistance voltage current
un-cooled infrared sensors can be stabilized to an operating temperature,
while they are not cooled down to low temperatures and do not require
bulky, expensive coolers. This provides smaller and less costly infrared
cameras. However, their resolution and image quality might be lower than
cooled detectors. This is due to differences in their fabrication processes,
which limited because of lack of needed technology.
IR-fusion image
IR-Fusion® technology enables the camera to capture both the visible
light image and infrared image at the same time. It is very beneficial in
terms of identifying and reporting suspected components and make the
repair process easier, you can combine both digital and infrared thermal
images for better clarity. This allows you to easily see, document, and
address problems uncovered through your thermal imaging work. Fluke's
unique technology provides pixel-for-pixel alignment of the digital and
infrared thermal images, allowing you unlimited options in optimizing your
on-camera and off-camera analysis. The images to the right show
matched images.

Fluke TiR32 and operation
Infrared energy (temperature) images can be taken with fluke thermal
imager. This device is able to amalgamate observable light with the
energy of infrared images on the same screen. The process of discovering
temperature changes (heat patterns) in articles is called thermography or
thermal imaging. By monitoring temperature changes, the user may
benefit from scheming early maintenance plans in order to avoiding pricey
downtimes or any possible difficulty.

Setting Emissivity
The of a material (usually written or ) is the relative ability ofemissivity e
its surface to emit energy by radiation. It is the ratio of energy radiated by
a particular material to energy radiated by a black body at the same
temperature. A true black body would have an = 1 while any real object
would have < 1. Emissivity is a dimensionless quantity.
In general, the duller and blacker a material is, the closer its emissivity is
to 1. The more reflective a material is, the lower its emissivity. Highly
polished silver has an emissivity of about 0.02.

3. Press the softkey labeled to select the set value.Done
4. Wait for main menu to disappear or quickly squeeze and release the
trigger twice in order to return to live view.
Making accurate temperature measurements
All the objects radiate infrared energy and this energy is based on two
factors: surface temperature of the object and emissivity of the object’s
surface. Imagers use the information from detecting infrared to estimate
the object temperature.
Objects are in two categories: low emissivity and high emissivity
High emissivity: are efficient at radiating energy and emissivity
factor estimated to be 95% like wood, water, cloth and etc.
Low emissivity: are not efficient at radiating energy. To obtain a
temperature accurately we can do emissivity correction in two
ways: directly entering value and use value of built-in value.
Note: If imagers use fixed value for emissivity, to get the accurate
estimate, the measurements must be multiplied by a value found in a look
up table.
SmartView Software

FAQ
- How we can solve artifacts?
If any of these artifacts do appear in your properly focused infrared image,
please be assured that it is only because there is not enough of a thermal
differential in the scene to indicate the presence of an anomaly or issue.
Typically, increasing span, changing color palette, or introducing a thermal
differential into the scene will eliminate the appearance of any artifacts.
- How can I set a date/ language?
you can use the F2 key to go to the Menu and use F1 and F3 to find the
setting for time and language.
-Why the image taken by the camera is mostly one color (all in blue
or red)?
This problem hapens when the color range of temperature which is shown
on the right side of the screen is not set properly. Look the description in
the Setting the level . Also it can be result of a situation which the thermal
camera is not collaborated with the surrounding temperature. you need to
wait for a while or you may need to turn off and then turn it on again.
