    Operational Theory Insta Trans-XD 2.2.2 Anatomy of a Micro-fuel Cell The Micro-fuel Cell is a cylinder only 1¼ inch in diameter with a length dependent on the particular cell. It is made of an extremely inert plastic, which can be placed confidently in practically any environment or sample stream.

  • Page 22: The Effect Of Pressure

    Operational Theory Insta Trans-XD (Two electrons are transferred for each atom of lead that is oxidized. Therefore it takes two of the above anode reactions to balance one cathode reaction and transfer four electrons.) The electrons released at the surface of the anode flow to the cathode surface when an external electrical path is provided.

    Figure 2-3. Measuring circuits do not have to compensate for nonlinearities. In addition, since there is zero output in the absence oxygen, the characteristic curve has close to an absolute zero (within ± 0.5 ppm oxygen).

  • Page 24: Sample System

    Depending on the mode of operation either sample or calibration gas is delivered. The Insta Trans-XD is designed and fabricated to ensure that the oxygen concentration of the gas is not altered as it travels through the internal piping. The sample encounters almost no dead space. This minimizes residual gas pockets that can interfere with trace analysis.

  • Page 25: Electronics And Signal Processing

    Oxygen Transmitter Operational Theory 2.4 Electronics and Signal Processing The Insta Trans-XD Oxygen Transmitter uses standard electronic circuitry. Power is supplied via the 4-20 mA current loop. The processing electronics are located inside the transmitter housing. The single PC board shown in Figure 2-5 is accessible after removing the front cover of the housing.

  • Page 26: Figure 2-6: Electronics Block Diagram

    Range selection and calibration information are entered from the keypad and processed by the microcontroller. All power needed to run the Insta Trans-XD transmitter is derived from the signal current loop. Range and calibration settings are maintained indefinitely when the signal current loop is disconnected.

    Immediately report any damage to the shipping agent. 3.2 Mounting the Transmitter The Insta Trans-XD transmitter is provided with a wall mount bracket. Refer to Figure 3-1 and the Outline Drawing in the Appendix for mounting information and dimensions. The display and operator control switches are located on the top of the transmitter.

    (9.3V + (5.1 + 250) ohms x 20ma). For Intrinsically Safe (IS) installation, special considerations are required. The Insta Trans-XD analyzer has been designed to be Intrinsically Safe when used with a properly selected and installed safety barrier. This design utilizes redundant safety features to prevent the Insta Trans-XD from becoming an ignition source in the event of a circuit failure.

    The characteristics of the sensor which is a micro-fuel cell, show an almost constant output throughout its useful life and then falls off sharply towards zero at the end. Cell failure in the Insta Trans-XD is usually characterized by the inability to span or excessive offset when used on low ppm ranges.

    Maintenance Insta Trans-XD The B1, B2C, Insta-Trace, and L2C cells are not designed for applications where CO is a major component in the sample, however intermittent concentrations of 1,000 pm or less will not adversely affect the cell performance. Consult TAI for available options for either intermittent or continuous CO exposure.
