4040 - Methane / Nonmethane analyzer - Teledyne Analytical ...

IntroductionIntroductionTeledyne Analytical Instruments Series 4040, Methane/ NonmethaneAnalyzer, is designed to measure the quantity of variety ofhydrocarbons present in the sample gas. The Analyzer is amicroprocessor controlled digital instrument based on Teledyne’s highlysuccessful Model 402R series analog Total Hydrocarbon Analyzer,coupled with a gas separation Column and a switching valve. TheAnalyzer allows for the separation and measurement of methanehydrocarbon from the rest of the hydrocarbons in the low ppm range.1.1 Main Features of the AnalyzerThe Analyzer is sophisticated yet simple to use. A dual display onthe front panel prompts and informs the operator during all phases ofoperation. The main features of the analyzer include:1. Easy-to-use front panel interface that includes a red 5-digit LEDdisplay and a vacuum fluorescent display (VFD), driven bymicroprocessor electronics.2. High resolution, accurate readings of concentration.3. Versatile analysis with three user-definable analysis ranges.4. Microprocessor based electronics: 8-bit CMOS microprocessorwith 32 kB RAM and 128 kB ROM.5. Auto ranging allows analyzer to automatically select the properpreset range for a given measurement. Manual override allowsthe user to lock onto a specific range of interest.6. Two adjustable concentration alarms and a system failure alarm.7. Extensive self-diagnostic testing at startup and on demand.8. RS-232 serial digital port for use with a computer or other digitalcommunication device.9. Analog outputs for concentration and range identification (0-1VDC standard and isolated 4-20 mA dc).10. Superior AccuracyTeledyne Analytical Instruments 15
