IW4000, 100mm (4”) SMARTInfrared IR Window.

When panel front space is at a premium, or you simply want to view a single item in your equipment the IW4000 SMART Infrared IR Window is the most cost effective solution available. A fully featured SMART Infrared IR Window with crystal optic the IW4000 is the most cost effective Infrared IR Window of its type. The HydroGARD® coating – exclusive to CorDEX infrared windows – sales both front and rear faces plus the edges of each crystal optic prior to assembly to ensure total protection against moisture, mild acids and alkalis.

Each CorDEX SMART Infrared IR Window comes complete not only with the embedded RFID tag for wireless identification but with two additional identification methods; barcode and human readable. So whether or not you use RFID technology, the SMART Infrared IR Window has you covered.

With its ¼ turn quick release lock and spring loaded cover, the IW Series is simple to use and requires no disassembly during the installation process. The team at CorDEX have years of experience installing SMART Infrared IR Window and we know how much pressure an installer can be under during a shutdown. Drawing on this wealth of experience and by listening to our customers we include a free access key with every SMART Infrared IR Window along with a tear off self adhesive drilling template that leaves no residue on the panel, the template even has a non-adhesive corner making it simple to grab and remove. During an installation, we know that fixing screws are easily lost costing time and increasing pressure on the installer, so we add an extra one with every IR Window, just in case.

Are the IR Windows lenses water soluble?

The crystal lens material is not water soluble.

However, the IW Series has a HydroGARD protective coating to help protect them from all elements. The IW Series Windows all have an IP65 rating.

Can your IW Series Windows be used with any IR camera?

YES. The IW Series Windows are designed to be used with ALL IR CAMERA’S. The only consideration is what operating environments and equipment should be used when making your inspections.

How do I change the alias name for a particular RFID tag?

  1. Ensure your UT5000 is powered on.
  2. Place UT5000 within range of RFID Tag.
  3. Press the RFID scan key [SCAN]
  4. Press setup key [SETUP]
  5. Highlight ‘tag setup’ from the list using arrow
  6. keys, then press select key [SEL]
  7. Highlight ‘edit tag alias’ from the list using
  8. arrow keys, then press select key [SEL]
  9. Highlight ‘del’ from the list using arrow keys, then press select key [SEL] until previous alias is removed. Enter required tag alias using arrow keys, pressing select key [SEL] after each digit.
  10. When required name is entered scroll to ‘accept’ and press select key [SEL]

How long is the warranty on your IR windows?

The IW Series Intelligent IR Windows are guaranteed against any manufacturing defects and for the life of the panel in which they are fitted, they are not guaranteed against damage or misuse.

Is it important to have a high transmission rate?

It is imperative to understand your IR transmission rates and wavelengths that your IR window works in. The transmission of your IR window is needed to accurately calculate your temperature correction. The IW Series Intelligent IR Windows are all individually tested in a transmission correction chamber to calculate their individual transmission rates. Using RoutePLANNIR™ or the IW Series Installation App it is possible to get these readings on site.

Is the IW Series Intelligent IR Window flame proof?

NO. Flameproof is a term used when designing hazardous area equipment. The materials used in the construction of the IW Series IR Windows are all flame retardant and certified by Underwritiers Laboratories (UL) to UL94.

Is Your IR window more accurate than the competitions?

The IW Series Intelligent IR Window on its own is not more accurate than any competitor Window. The introduction of the transmission correction data given in RoutePLANNIR™ and on the IW Series Installation App on each individual IW Series Windows allows the user to gain the exact correction data for that window and in turn giving you the user a more accurate reading.

What are the thicknesses of your lens materials?

Our standard crystal thicknesses are:

IW3000 – 2mm (0.08in)
IW4000 – 4mm (0.16in)

What effect do the windows have on the thermal image?

When taking a thermal image, the IR Windows will always absorb some of the infrared radiation emitted by your source. This is where the transmission correction is vital. Using the RoutePLANNIR™, CorDEX CONNECT™ or the IW Series Installation App (for iPhone) you can obtain your correction data quickly and easily whilst on site.

What is the range of the RFID Scanner on the TC7000 and TC7150?

The range of the RFID scanner on TC7000 and TC7150 is limited to approximately 50mm (2”) although this does also depend somewhat on the tag.

Who can install and service an IR window?

The IW Series Intelligent IR Window must be installed and serviced only by qualified electrical personnel, in accordance with local safety codes and legislation

Why is the actual transmission rate so important?

All Infrared windows transmit infrared energy at varying levels, this is known as the transmission rate. The IR Window transmission determines the amount of infrared energy the thermal imager receives and correspondingly, the temperature the camera displays to the thermographer. To be able to calculate the temperature of a component behind an IR Window there are a number of variables for the operator and camera to consider which include:

  • IR Window Transmission
  • Target Emissivity
  • Ambient/Background temperatures
  • Distance

With all of these variables and measurements taken into consideration the camera will use this data to calculate a temperature using a sophisticated algorithm. Without all of these variables it is difficult to get an accurate temperature reading from your target located inside the panel.
The IW Series Intelligent IR Windows are all individually transmission checked across the general operating range for an electrical pdm inspector (+35C – +165C). The broad calibration routine enables the IW Series IR Windows to access specific calibration maps which take into account the spectral nature of a typical IR Window transmitter.

No other IR Window manufacturer provides this level of accuracy to thermographers. For more information on IR Window transmission go to our Learning Lab section and select the “Understanding Transmission” Lab.

Will the TC7000 work only with your SMART IR Windows?

Both the TC7150 and TC7000 will “see” through any IR Window compatible with Longwave infrared imagers. The additional features associated with CorDEX CONNECT and CorDEX SMART IR Windows are an added benefit of using instruments designed as a complimenting system.

You say that TC7150 is compatible with the IW Series SMART IR Windows, what does this mean?

Both TC7000 and TC7150 have onboard 13.5Mhz RFID scanners which means that they can communicate directly with the IW Series SMART IR Windows. The SMART IR Window wirelessly responds with a unique ID code embedded in a chip within the IR Window which enables the camera to download transmission specific data for that IR Window type from the CorDEX Servers.

Once the camera has this data, it automatically tags images taken via the IR Window for later seamless correlation via CorDEX CONNECT database software. The camera also automatically enables complex on-board correction algorithms to remove the error caused by the IR Window itself.

The result, accurate measurements with no more pen and paper attempts at correlating hundreds of IR Window images with the correct location. The combination of TC7000, IW Series SMART IR Windows and CorDEX CONNECT database package takes the load and provides accurate results, every time.
