Abstract

This invention adapts a variable emissivity radiometer for non-contact temperature measurement by adding a programmable feature where a microprocessor and EPROM are incorporated into a radiometer. This enables the emissivity of the component to be measured to be pre-programmed into the device. When the machine model number and part number is entered, the correct emissivity of that object is pre-selected so accurate measurements can be taken. Without this information entry, the unit will not measure temperature.

Programmable Radiometer for Use on Various Emissivity Materials

 

This invention adapts a variable emissivity radiometer for non-contact temperature measurement by adding a programmable feature where a microprocessor and EPROM are incorporated into a radiometer. This enables the emissivity of the component to be measured to be pre-programmed into the device.  When the machine model number and part number is entered, the correct emissivity of that object is pre-selected so accurate measurements can be taken.  Without this information entry, the unit will not measure temperature. 

In remote temperature measurement, knowledge of the component’s emissivity is necessary for an accurate reading.  One type of radiometer, has been shown to be more accurate because it has a digital, adjustable emissivity feature.  However, the user must enter the correct number for the emissivity of the material whose temperature is being read.  For the field measurements, this is undesirable since mistakes on emissivity entry could result in incorrect temperatures being read. 

The use of a microprocessor and EPROM to select the proper emissivity based upon the requirement of entering machine model number and part number before it will read a temperature would allow this device to be used across multiple programs and applications and reduce the chance of incorrect measurements by unqualified personnel.
