Description for Fieldpiece ATIR3

Overview
The Fieldpiece Non-contact Infrared Temperature Accessory with Laser Sight, model ATIR3, collects infrared energy (IR) and converts it to a mVDC signal that is proportional to the temperature being measured. The temperature measured is the average of all the temperatures in the 8:1 cone of viewability. The closer you are to the target, the smaller the area measured. The further away, the larger the area. The digital, non-contact ATIR3 converts the Fieldpiece "Stick" series meter, DL3 data logger, and EHDL1 electronic handle to a one-piece infrared, or IR, thermometer. Use the optional Fieldpiece ADLS2 deluxe silicone test leads or the AHDL1 adapter handle with the ATIR3 for use with DMMs with industry standard jacks.

How Does It Work?
Non-contact infrared temperature measurement is fast and easy. It works best for fast readings, relative readings (one to another or the same one at different times), or temperature readings of hard to reach places. The following are some applications:

  • Heating and air conditioning where fast and/or easy measurement is most important
  • Motor bearings: high temperature can indicate bearings that might need replacement
  • Circuit breakers: a circuit breaker that is not operating properly can get hot. By scanning a panel, you will be able to find the hot one.
  • Poor power line connections: a bad connection can get hot

IR Temperature Measurement
When something is hot, it radiates infrared (IR) energy. The hotter it is, the more infrared energy emitted. If there's enough of it, you can feel it. The ATIR3 infrared accessory head collects infrared energy from a cone-shaped viewing area and measures the total amount of energy collected. The ATIR3 converts the total energy measured to a temperature. Distance doesn't matter because the further you go from the target, the increase in area "seen" by the sensor exactly balances the loss of energy collected from a given area.

If you want to get the temperature of something small, you must get close enough so the surface takes up the whole viewing area circle. Otherwise the surface and the background temperatures will be averaged into the reading.

The accuracy of many infrared temperature measuring systems is adversely affected by ambient temperature.

You need to be aware that if the target surface is reflective enough, it may reflect infrared from other objects. For example, if you take a reading of a shiny metal surface, the infrared energy of your face may reflect enough energy off the surface to affect the reading.

"Emissivity" of the target surface also affects the temperature reading. For a given temperature, the higher the emissivity, the higher the reading. The lower the emissivity, the lower the reading. Emissivity of a surface indicates how easy it is for the infrared to get out. Emissivity for a dull, black surface is high (nearly 100%) so it's easy for the infrared to get out. Emissivity for a shiny surface can be much lower. If the emissivity is low, the measured temperature will be lower than actual. For relative readings of the same kind of surface, this isn't a problem. For some applications, it may be necessary to spray dull, black paint on the target to insure a more accurate reading.

For best accuracy use contact sensors (thermocouples, thermistors, etc.) anytime you take a temperature measurement. Infrared instruments should only be used when you aren't able to touch the surface to be measured.
