  • Page 7: Overview

    Overview The Teledyne Electronic Technologies Analytical Instruments (TETAI) Model 3300PB is a microprocessor-based percent oxygen analyzer for real- time measurement of the percent of oxygen in inert gases, or in a wide variety of gas mixtures. It features simple operation, fast response, and a compact, rugged construction.

  • Page 11: Operational Theory

    Micro-Fuel Cell Sensor 2.2.1 Principles of Operation The oxygen sensor used in the Model 3300PB is a Micro-Fuel Cell de- signed and manufactured by TAI. It is a sealed, disposable electrochemical transducer. The active components of the Micro-Fuel Cell are a cathode, an anode, and the aqueous KOH electrolyte in which they are immersed.

  • Page 12: Anatomy Of A Micro-Fuel Cell

    The space between the active elements is filled by a structure saturated with electrolyte. Cathode and anode are wet by this common pool. They each have a Teledyne Analytical Instruments...

    If the pressure changes, the rate that oxygen reaches the cathode through the diffusing membrane will also increase. The electron transfer, and therefore the Teledyne Analytical Instruments...

    Model 3300 Location and Mounting 3.2.1 Control Unit Installation The 3300PB 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. Refer to the Outline diagram D-69220 for the physical dimensions of the analyzer.
  • Page 19 There is one set of contacts for each type of alarm. Contacts are Form C, with normally open and normally closed contact connections capable of switching up to 0.5 ampere at 125 VAC into a resistive load (2A for 30 VDC). Teledyne Analytical Instruments...

  • Page 31: Replacing The Fuse

    Maintenance Aside from normal cleaning and checking for leaks at the gas connections, the Model 3300PB should not require any maintenance beyond replacement of expended Micro-Fuel Cells, and perhaps a blown fuse. Routine maintenance includes occasional recalibration, as described in chapter 4, Operation.
