ATi’s E12-15 IR Infrared High Level Ammonia Gas Detector is a rugged, reliable, microprocessor-based, intelligent gas detector. The E12-15 IR can be used to monitor from PPM levels to explosive levels of ammonia gas. The E12-15 IR is ideally suited for use in harsh environments where electrochemical sensor life can be short. Areas such as engine rooms, emergency vents, or other high level NH3 areas are excellent applications.
The E12-15 IR Infrared Gas Detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology. The E12-15 IR is a stand-alone device providing a linear continuous 4 to 20 mA output representing 0 to full scale.
The Model E12-15 IR Infrared Gas Detector uses infrared absorption technology for detecting ammonia gas. Gases absorb infrared light only at certain wavelengths. The concentration of a gas can be quantified by measuring and comparing intensities in light bands where there is significant absorption by the target gas in bands where there is little absorption by the target gas.
The Model E12-15 IR uses an infrared light source that passes collimated light through a waveguide containing the gas sample. At the other end of the waveguide is a multiple channel receiver. The measuring channel intensities and the reference channel intensities are then analyzed to quantify the gas concentration. The gas concentration is then represented at the output as a gas density measurement of % Vol measurement or PPM.
