Model GFC7000E Instruction Manual THEORY OF OPERATION 10. THEORY OF OPERATION The Model GFC7000E Gas Filter Correlation Carbon Dioxide Analyzer is a microprocessorcontrolled analyzer that determines the concentration of carbon dioxide (CO2) in a sample gas drawn through the instrument. It requires that sample and calibration gasses be supplied at ambient atmospheric pressure in order to establish a stable gas flow through the sample chamber where the gases ability to absorb infrared radiation is measured.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.1.2. Measurement Fundamentals In the most basic terms, the Model GFC7000E uses a high energy heated element to generate a beam of broad-band IR light with a known intensity (measured during Instrument calibration. This beam is directed through multi-pass cell filled with sample gas. The sample cell uses mirrors at each end to reflect the IR beam back and forth through the sample gas to generate a 2.5 meter absorption path (see Figure 10–1).
Model GFC7000E Instruction Manual THEORY OF OPERATION Measurement Cell (Pure N2) Reference Cell (N2 with CO2) Figure 10-2: GFC Wheel A GFC wheel is a metallic wheel into which two chambers are carved. The chambers are sealed on both sides with material transparent to 4.3 µm IR radiation creating two airtight cavities. Each cavity is filled with specially composed gases. One cell is filled with pure N2 (the measure cell).
Model GFC7000E Instruction Manual THEORY OF OPERATION does not absorb IR light. This results in a fluctuation in the intensity of the IR light striking the photo-detector (See Figure 10-3) that results in the output of the detector resembling a square wave. The Model GFC7000E determines the amount of CO2 in the sample chamber by computing the ratio between the peak of the measurement pulse (CO2 MEAS) and the peak of the reference pulse (CO2 REF).
Model GFC7000E Instruction Manual THEORY OF OPERATION calibration SLOPE and OFFSET values to produce the CO2 concentration which is then normalized for changes in sample pressure.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.1.4. Ambient CO2 Interference Rejection CO2 absorbs IR light very well. So well that even the narrow volume of ambient air between the IR source and the sample chamber is enough to alter the analyzer’s measured concentration of CO2. Also, ambient air, which averages around 350 ppm to 400 ppm, will vary significantly over the course of the day.

Model GFC7000E Instruction Manual THEORY OF OPERATION CRITICAL FLOW ORIFICE AREA OF LOW PRESSURE AREA OF HIGH PRESSURE Sonic Shockwave SPRING Figure 10-8: O-RINGS FILTER Flow Control Assembly & Critical Flow Orifice The actual flow rate of gas through the orifice (volume of gas per unit of time), depends on the size and shape of the aperture in the orifice. The larger the hole, the more gas molecules, moving at the speed of sound, pass through the orifice.
Model GFC7000E Instruction Manual THEORY OF OPERATION Particulate Filter The Model GFC7000E Analyzer comes equipped with a 47 mm diameter, Teflon, particulate filter with a 5 micron pore size. The filter is accessible through the front panel, which folds down to allow access, and should be changed according to the suggested maintenance schedule described in Table 9-1. 10.2.1.4.
Model GFC7000E Instruction Manual THEORY OF OPERATION • Through the analyzer’s keyboard and vacuum florescent display over a clocked, digital, serial I/O bus (using a protocol called I2C); • RS 232 & RS485 Serial I/O channels; • Via an optional Ethernet communications card: • Various DCV and DCA analog outputs, and • Several sets of Digital I/O channels.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.3.2. CPU The Model GFC7000E’s CPU is a, low power (5 VDC, 0.8A max), high performance, 386-based microcomputer running MS-DOS. Its operation and assembly conform to the PC/104 Specification version 2.3 for embedded PC and PC/AT applications. It has 2 MB of DRAM on board and operates at 40MHz over an internal 32-bit data and address bus.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.3.3.2. IR Source The light used to detect CO2 in the sample chamber is generated by a element heated to approximately 1100oC producing infrared radiation across a broad band. This radiation is optically filtered after it has passed through the GFC Wheel and the sample chamber and just before it reaches the photo-detector to eliminate all black body radiation and other extraneous IR emitted by the various components of those components. 10.3.3.3.

Photo-Detector Temperature Control The synch/demod board also contains circuitry that controls the IR photo-detector’s thermoelectric coolers.
Model GFC7000E Instruction Manual THEORY OF OPERATION GFC Wheel Motor Control: The GFC wheel operates from a AC voltage supplied by a multi-input transformer located on the relay board. The step-down ratio of this transformer is controlled by factory-installed jumpers to adjust for 100 VAC, 115 VAC or 230 VAC line power. Other circuitry slightly alters the phase of the AC power supplied to the motor during start up based on whether line power is 50Hz or 60 Hz.

Should this LED ever stay ON or OFF for 30 seconds, the watchdog circuit will automatically shut of all valves as well as turn off the IR Source and all heaters.
Model GFC7000E Instruction Manual THEORY OF OPERATION For calibration purposes, two reference voltages are supplied to the A/D converter: Reference Ground and +4.096 VDC. During calibration, the device measures these two voltages, outputs their digital equivalent to the CPU. The CPU uses these values to compute the converter’s offset and slope and uses these factors for subsequent conversions. See Section 6.9.4 for instructions on performing this calibration. 10.3.6.2.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.3.6.4. Analog Outputs The analyzer comes equipped with four analog outputs: A1, A2, A3 and a fourth that is a spare. A2 and A1 Output The first two, A2 and A1 are normally set up to operate in parallel so that the same data can be sent to two different recording devices. While the names imply that one should be used for sending data to a chart recorder and the other for interfacing with a datalogger, either can be used for both applications.
Model GFC7000E Instruction Manual THEORY OF OPERATION 10.3.6.6. External Digital I/O This External Digital I/O performs two functions. Status Outputs Logic-Level voltages are output through an optically isolated 8-pin connector located on the rear panel of the analyzer. These outputs convey good/bad and on/off information about certain analyzer conditions. They can be used to interface with certain types of programmable devices (see Section 6.13.1.1).
