Ultima OPIR-5 Detector

 

7 

In normal operation, the microprocessor program constantly monitors the two infrared 
wavelengths and performs mathematical operations on this information in conjunction with 
values obtained during the factory calibration process. 

The microprocessor derives output information and feeds it to the digital to analog converter 
to produce two 4 to 20 milliampere (mA) signals that are proportional to the 0 to 5,000 
ppm•meter and 0 to 5 LEL•meter for the methane sensing unit and 0 to 2,000 ppm•meter and 
0 to 1 LEL•meter for the propane unit. The 4-20 mA signal is converted to gas concentration 
in % of full scale using the formula [(Analog Output – 4)/16] * (100% full scale), where Analog 
Output is the 4-20 mA signal. 

  The microprocessor program also monitors aspects of system operation such as supply 

voltage and optical path integrity.
