The Optopair consists of high-effective Photodetector and special solid state pulsed Light Emitter. The spectral response of the Photodetector and spectral emission of the Light Emitter are precisely coordinated for effective operation at absorption lines of measured gases. Additional built-in narrow band filters mounted onto Photodetector (or/and Light Emitter) provide high selectivity of measuring schemes. Standard options of the Optopairs are suitable for analyzing of CO2 (carbon dioxide), CH4 (methane), hydrocarbons mixtures (CnHm). Other gas options are available on request. Optopairs with built-in TE cooling and thermostabilization are presented as standard options, as well as uncooled simpler types. Two Optopair series are available: u Optopair consisting of discrete Light Emitter and Photodetector u Integrated Optopair consisting of two Light Emitters and Photodetector assembled in the single TO8 package. Features u u u u u u u No moving parts Miniature design Low power consumption Standard options for a range of measuring schemes Long operation lifetime High speed of response High selectivity Available Options Optopair Type Measured Gas Formula l1, mm l2, mm Dl, mm OPR(i)x-4239 Carbon Dioxide CO2 4.28 3.90 0.12 OPR(i)x-3439 Hydrocarbons CnHm 3.42 3.90 0.25 OPR(i)x-3230 Methane CH4 3.23 3.0 0.08 Notes: 1) Index “i” is valid for integrated type of optopairs 2) Code “x” means uncooled or TE cooled type (see chapter “How to select an Optopair”).

Advantages u u u u u u u u High selectivity and stability Wide range of measured concentrations Small gas sampling cell Fast response The principle of operation is based on selective absorption of IR radiation by gas molecules. The differential double frequency optical scheme provides a high accuracy in wide ranges of humidity and temperature due to the internal thermostabilization. A new type of middle infrared (IR) integrated Optopair (Detector and Light Emitters) with built-in thermoelectric cooling is used. The light sources are pulsed solid state middle-IR Light Emitters. The Photodetector is based on the Lead Selenide (or Lead Sulphide) photoresistor. There are several models suitable for the following gases: CO2, CH4, CnHm. Other optional gas analyzers are available on request. Both complete modular and OEM versions are available.

The analyzer provides gases concentration measurement based on the classical double channel optical scheme. One of the beams (measuring channel) has the wavelength tuned to the optical absorption line of the measured gas. The other beam (reference channel) has the wavelength that is out of the adsorption band of the measured gas. After passing through the gas sampling cell the two light beams intensities are compared. actual measurements conditions: total transparency of gas volume, optics imperfection and so on. The reference channel is used for indirect measuring of the initial light intensity and allows to eliminate The principle of gas concentration measurement realized in the DX6100 analyzer Design Features The DX6100 Gas Analyzer is specially designed for fast response, high sensitivity, low noise and low power consumption. A number of design features contribute to the performance : u The infrared sources are special narrow-band pulsed Light Emitters operating in a microsecond range. The light sources have long life (more than 10,000 hours). u Radiation from Light Emitters passes through gas sampling cell, reflects from the mirrors and is focused onto wide-band Photodetector. u Light Emitters and Photodetector chips are integrated into a single housing and placed onto a miniature TE cooler for thermostabilization. u Microcontroller provides temperature regulation with better then 0.1°C accuracy. The temperature is software selectable from the ambient value down to –20°C. u Heat dissipated from the warm side of TE coolers results in few degrees of overheating of gas sampling cell above the ambient. This factor plays the role of vapor anti-condensation at high moisture operation. u All driving function of Light Emitters and 24 u u u Detector are operated by the on-board microcontroller. Pre-amplified outputs are maintained by the microcontroller. The final result is digital data of measured gas concentration and is available in realtime through the RS-232C or an analog port. For the signal processing the calibrated data of Optical Unit is used. The data is stored in Optical Unit’s EEPROM. The RS-232C port is also used for the remote control from a computer.

The individual calibration of device is required using standard gas mixtures. The Detector output signal is non-linear with respect to the measured gas concentration. The intensity of light that passed through the gas sampling cell is the integral of various optical rays from Light Emitter. The sensitivity of Detector and performance of Light Emitter depend very much on their operating temperatures. The Detector output signals (both measuring and reference channels) are measured while calibration gases with known concentration are passing through the gas sampling cell. The data obtained are used for polynomial extrapolation of calibration results. The polynomial coefficients and the “zero” ratio are stored into the device internal on-board EEPROM memory. The first calibration is made by the manufacturer. The factory standard calibration uses not fewer than five standard gas mixtures. Several calibrations are made at different ambient temperatures (in the specified operating range) and at corresponding optimal operating temperatures of the integrated Detector-Emitter pair. It is possible to store up to 15 such calibrations for further application. Noise level Default values are extracted by the device microcontroller from the memory and correspond to the ambient conditions at calibration procedure. It is also possible to use the value of measured ambient temperature provided by the on-board digital thermosensor. 3. To preserve high accuracy of the device it is necessary to make “zero” adjustments periodically as recommended in the DX6100 User’s Guide. 4. Periodicity of the device recalibration is 1 year. It can be done at the Manufacturer’s factory or by a user with the help of the corresponding DX6100 Vision II software. 390 Time constant=1.0 s CO2 Concentration, ppm The main parameter of the digital filter is Time constant. It is adjustable in the range 0.1…60 s. The values of ambient temperature and pressure can be inputted by a user manually into the device memory at the beginning of the experiment. Time constant=0.1 s CO2 Concentration, ppm Adjustable noise level is realized due to application of digital filtration algorithm. 370 350 330 310 1 31 61 91 121 390 370 350 330 310 151 1 31 370 350 330 310 61 91 Time, s RMT Ltd. 91 121 151 121 151 Time constant=5.0 s CO2 Concentration, ppm CO2 Concentration, ppm Time constant=0.2 s 390 31 61 Time, s Time, s 1 Gas Analyzers 2. During a routine operation the detector output signals are measured. Using a known “zero” value and polynomial coefficients the gas concentration is calculated with a high accuracy as a function of measuring and reference channels signals ratio. Resulted concentration is calculated in absolute mmol/m3 units. The device provides (if required) recalculation of the concentration into relative ppm units. But to convert absolute units (mmol/m3) into relative (ppm) ones it is necessary to know ambient temperature and pressure. 390 370 350 330 310 1 31 61 91 121 151 Time, s 53 Leninskij prosp.

It consists of an isolated gas sampling cell (the spherical mirror and the sapphire window are placed at the end sides) and a new generation integrated optopair with the DX6102 electronic mating module. The internal volume of the gas cell depends on the Optical Unit version. The gas sampling cell has two gas inlets with 5.0 mm internal diameter. The gas sampling cell can be easily disassembled for the service of the internal optics (mirror and window). For this purpose both the top and bottom covers can be removed and the optical components extracted. The mirror has a special SiO2 safety layer. The DX6106 Optical Units are manufactured in two versions: with DX6106.C2 and DX6106.C4 gas sampling cells (See Table).

But for many purposes, such as the change of tunings of the analyzer, zero adjustment, calibration and so on, the control computer is necessary. A user can control the Analyzer with computer in two ways: 1) The remote control by the Analyzer is available using the RS-232 port by a set of microcontroller commands. The commands can be divided into two groups: driving commands and setting commands. All commands have the same format – the symbol string, which consists of the command name identifier and a list of its parameters. Some commands have no parameters. The commands are described in User’s Guide. This way is very useful if a user is going to integrate the DX6100 analyzer into a more complicated system. 2) The second way is based on using the DX6100 Vision II software. DX6100 Vision II Software The DX6100 Vision II software provides all possible operational modes of the DX6100 Gas Analyzer. The software has a simple interface and does not demand a User's special knowledge. The software is delivered with the DX6100 Gas Analyzer. Also it is available for free dawnload from RMT website: www.rmtltd.ru Setup Window System Requirements To run the DX6100 Vision II software the following system requirements must be met or exceeded: u Intel Pentium class computer with Windows 95/98/2000 operating system u Free COM port u 16 MB of RAM (32 MB recommended) u 6 MB free hard drive space u CD ROM drive u Mouse or compatible pointing device Main Window 28 RMT Ltd. 53 Leninskij prosp.

The following parameters are among them: u Parameters of Light Emitters and Photodetector operation (pulse duration, Emitter current, Detector gain, synchronization and others) u Telemetry structure (output parameters, repeating rate, duration of measurements and others) u Warning levels u Analog output adjustment and others But before editing a parameter study the device description thoroughly, please. Many of available parameters should be adjusted very carefully by experienced users only or along the manufacturer’s recommendation. Gas Analyzers Parameters of Analyzer Adjustment Setting Window Calibration One of the very useful utility of the DX6100 Vision II software is Calibration subroutine. The program allows users to carry out quite a complex procedure of the device calibration. The first calibration in a specified concentration range is made by the manufacturer. A user can perform any recalibration with the use of the program. According to the instructions the procedure consists of several steps that must be completed by a user. First of all, a user need to have a set of standard gases with concentrations in specified range. Then a user is to start the Calibration program and follow instructions step-by-step. The advisable periodicity of the device recalibration is 1 (one) year. It could be done at the factory of the manufacturer or by a User with the help of DX6100 Vision software. Zero Adjustment To ensure high accuracy, a simple adjustment can be made during operation to adjust the “zero” ratio. The procedure requires to start the sensor in the Calibration mode and to flow up any "zero" gas through the gas sampling cell. The new “zero” coefficient will be stored in EEPROM in place of the old value after the adjustment procedure is complete. RMT Ltd. Calibration Procedure 53 Leninskij prosp.
