Study on portable motorcycle exhaust gas analyzer

in this paper, a new portable motorcycle exhaust gas method NDIR is used to measure CO, CO2 and HC, the electro-chemical mean is used to test NOX and O2. the speed and the thermal resistance is used to obtain the oil temperature. this analyzer is composed of the sample system, gas examination system, secondary integrated in a small box. its hardware includes an embedded 586 motherboard, a LCD display, a USB communication interface and a mini-printer. the operating mode law is used for date gathering and processing. the usability and beautify in the outward appearance is also considered. in the design precision, analyzers. moreover, the analyzer also can be easily maintained, so it can be widely used.

ir400 infrared gas analyzer

the ir400 is capable of simultaneously and continuously measuring sample gas concentrations for O2 and up to four additional components from the following NO,SO2 CO, and CH4. A highly sensitive and reliable mass flow type twin detector makes measurements much less susceptible to interference from other components. the ir400 has a large multiple function LCD that improves operability and enables high accuracy. the ir400 is an ideal system for the measurement of combustion exhaust gases from waste incinerator and boilers as well as gases from various types of industrial furnaces.

Microfabricated Gas Chromatograph for Trace Analysis

Microfabricated portable gas analyzers with high sensitivity and selectivity offer utility in a variety of critical applications including aviation security, food safety and toxic industrial waste monitoring. An integral component of such analyzers is the gas chromatographic (GC) colmn which is used for separations of an injected mixture based on the relative sorption of the various analytes in the carrier gas by the stationary phase. In this interim report, we describe out efforts in the design and development of a microfabricated GC column for the trace detection of hazardous chemicals. Specifically, in this work an optimized serpentine layout with a circular cross- sectional profile has been microfabricated. In this work, computational fluid dynamic (CFD)modeling has been employed as a method to aid in the GC column design optimization. Selectivity to hazardous hydrogen bond basic (HBB) analytes (e.g. TNT, GB, VX) was achieved by using an polymer HCSFA2 as the stationary phase. HCSFA2 offers a higher partition coefficient than the more commonly used polysloxanes.

Analysis and receiving of downlink GSM signal using spectrum analyzer

Coverage prediction can help cellular radio operator to predict the service area that to be covered based on received radio field strength. However, the field important and has to be carried out at a few locations. Receiving of cellular radio signal from a system operator including GSM (e.g. Maxis and Celcom)have been done by using spectrum analyzer around University of College Technology Tun Hussein Onn (KUiTTHO). This signal is t hen analyzed to determine strength, channels, etc. in this work, we have developed a monopole antenna to receive the signal for indoor and outdoor locations.

Spectrum Analyzer

when purchasing a spectrum analyzer you need to distinguish first between an analog type and a digital one. in an analog spectrum analyzer the middle frequencies are tuned in automatically. this means the machine will automatically measure and analyze the complete range of frequencies that is was originally programmed to do. the analog types are equipped with a variable band pass filter to do its job. unlike analog, digital spectrum analyzers incorporate the fast fourier transform of fft. fft is a mathematical process frequency spectrum. because the waveform is broken down into components and digitized, it is easier fro a computer to make precise measurements, compute the transformations, and process the audio information.
