2-1 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments Operational Theory 2. 1 Introduction The analyzer is composed of two subsystems: 1.
2-2 2 Operational Theory Model 3300 TB Teledyne Analytical Instruments Micro-Fuel Cell is therefore a hybrid between a battery and a true fuel cell. (All of the reactants are stored externally in a true fuel cell.
2-3 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments conductor connecting them, through some electrical circuitry, to one of the external contacts in the connector receptacle, which is on the top of the cell. 2.2.3 Electrochemical Reactions The sample gas diffuses through the Teflon membrane.
2-4 2 Operational Theory Model 3300 TB Teledyne Analytical Instruments external current, will increase, even though the proportion of oxygen has not changed. Fortunately, Dalton's Law confirms that every gas in a mixture contributes the same pressure to the mixture that it would exert if it were alone in the same amount in that same volume.
2-5 Trace Oxygen Analyzer Operational Theory 2 Teledyne Analytical Instruments 2. 3 Electronics 2.3.1 General The signal processing uses an Intel microcontroller with on-board RAM and ROM to control all signal processing, input/output, and display functions for the analyzer.
2-6 2 Operational Theory Model 3300 TB Teledyne Analytical Instruments In the presence of oxygen the cell generates a current. The sensor has an internal thermistor compensation network. The output of the sensor is converted to voltage millivolt range.
3-1 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments Installation of the analyzer includes: 1. Unpacking the system. 2. Mounting the Control Unit to a wall 3. Installing the Micro-Fuel Cell 4. Making the electrical connections. 5. Making the gas connections.
3 Installation Model 3300 TB 3-2 Teledyne Analytical Instruments 3 . 2 Location and Mounting 3.2.1 Control Unit Installation The 3300TB Control Unit is designed to be wall-mounted, in a general purpose, area. The unit should be installed at viewing level in a sheltered area.

3 Installation Model 3300 TB 3-4 Teledyne Analytical Instruments Analog Outputs: There are three DC output signal connectors with screw terminals on the panel.
3-5 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments The specific descriptions for each type of alarm are as follows: Alarm #1 Programmable as high or low alarm (actuates when concentration is above threshold). Can be set anywhere between 0 and 9999ppm, but must be set ABOVE the threshold set for the LO Alarm.
3 Installation Model 3300 TB 3-6 Teledyne Analytical Instruments 3.4.1 Vacuum Service Option For vacuum service pluming reference figure 3-4. The vacuum service option is recommended for applications in which the sample source is not pressurized. The customer must supply a pump and by-pass system to complete the sample system.
3-7 Trace Oxygen Analyzer Installation 3 Teledyne Analytical Instruments 3 . 5 Installation Checklist Before connecting the instrument to the power source and turning it on, make sure you have: • Correctly installed the Sample and Exhaust gas lines • Checked for leaks • Set the sample pressure to 5–10 psig (34.

Trace Oxygen Analyzer Operation 4 4-1 Teledyne Analytical Instruments Operation 4. 1 Introduction Once the analyzer has been mounted, the gas lines connected and the electrical connections made, the Analyzer can be configured for your appli- cation. This involves setting the system parameters: • Defining the user selectable analysis ranges.
4 Operation Model 3300 TB 4-2 Teledyne Analytical Instruments 4 . 2 Using the Function and Data Entry Buttons When no buttons on the Analyzer are being pressed, the instrument is in the Analyze mode. It is monitoring the anount of oxygen in the sample gas that is flowing through the sampling system.
Trace Oxygen Analyzer Operation 4 4-3 Teledyne Analytical Instruments 4.3.1 HI Range Setting the HI Range fullscale value defines the LEAST sensitive analysis range to be used.
4 Operation Model 3300 TB 4-4 Teledyne Analytical Instruments until the display reads the desired percent concentration. (if within 5 seconds no key is pressed, the instrument will return to the sample mode and display oxygen concentration).
Trace Oxygen Analyzer Operation 4 4-5 Teledyne Analytical Instruments 4 . 5 Selecting a Fixed Range or Autoranging The Model 3300TB can operate in fixed high, fixed low, or autoranging mode. To change modes: 1. Press and then release the SET HI RANGE and the SET LO RANGE buttons simultaneously.
4 Operation Model 3300 TB 4-6 Teledyne Analytical Instruments 4 . 7 Displa ying P er cent & PPM on the LED Display The analyzer displays the concentration in percent whenever the read- ing is over 9999 ppm. When the reading changes to percent, the LED display will alternate between flashing “PC” and the oxygen concentration.
5-1 Trace Oxygen Analyzer Maintenance 5 Teledyne Analytical Instruments Maintenance Aside from normal cleaning and checking for leaks at the gas connections, the Model 3300TB should not require any maintenance beyond replacement of expended Micro-Fuel Cells, and perhaps a blown fuse.
5-2 5 Maintenance Model 3300 TB Teledyne Analytical Instruments fuse holder will slide out. There are two fuses in use and are visible in the clip. 4. Remove the bad fuse and replace it with a 5x20mm 0.5 A, 250 VAC, IEC time lag (T) fuse (P/N F1128). 5.
