A multiplexer system for measurement of gaseous emissions Conference Paper uri icon


  • A multiplexer was designed for measurement of gaseous emissions from ground level area sources (GLAS) in order to sample multiple receptors with a single sensor. This multiplexer may be used in both local and remote measurements systems to increase the sampling rate of gaseous emissions. The multiplexer, when used in the local mode, is divided into three distinct control sections: lift control, zero air input, and sample control. When used in remote mode, only the sample control is used. The multiplexer uses LabVIEW software to control Fieldpoint distributed I/O modules (National Instruments). The increased data collection capacity with the multiplexer allows for nearly twice as many samples to be taken in the same amount of time while using the same protocol for sampling.
