Page 7: Overview
Overview The Teledyne Electronic Technologies Analytical Instruments (TET/AI) Model 3300TA is a microprocessor-based trace oxygen analyzer for real-time measurement of the parts per million 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 3300TA is a Micro-Fuel Cell designed 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... -
Page 13: Electrochemical Reactions
If the pressure changes, the rate that oxygen reaches the cathode through the diffusing membrane will also increase. The electron transfer, and therefore the external current, will increase, even though the proportion of oxygen has not changed. Teledyne Analytical Instruments... -
Page 14: Calibration Characteristics
The cell itself does not need to be zeroed. As the cell reaches the end of its useful life, the slope seen in Figure 2-2 decreases. In the Model 3300TA, the slope is monitored. If the inverse of the slope: Span Value (ppm) / Cell Output (nA) is over 4.447 ppm/nA, a sensor failure alarm is triggered, indicating that the cell... -

Installation 3 Electrical Connections Figure 3-1 shows the Model 3300TA rear panel of the control unit. For detailed pinouts, see the wiring/interconnection drawings in the Draw- ings section at the rear of this manual. To gain access to the terminal blocks, the analyzer door screws must be lossened, and the door opened. - Page 20 HI alarm will activate when concentration is above treshold, while a LO alarm will activate concentration is below treshhold.

Page 21: Gas Connections
Gas Connections The standard Model 3300TA has two inlets and one outlet fixture only. Calibration gasses can be connected into the "Span" inlet. All of the gas connections are 1/4 inch brass fittings. - Page 22 This valve is used to adjust the span flow rate to match the sample flow rate. Do not adjust the span flow rate with the flow control valve located on the analyzer for units with vacuum service options. Teledyne Analytical Instruments...

Set the sample pressure to 5–10 psig (34.5 - 68.9 kpa), nominal (for non-vacuum service units) • Set the flow Once the above checks have been made, you can connect to the power source. The instrument is now ready for operation. Teledyne Analytical Instruments... - Page 24 3 Installation Model 3300 Teledyne Analytical Instruments...

Page 31: Maintenance 5
Aside from normal cleaning and checking for leaks at the gas connections, Category II the Model 3300TA 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. -

Trace Oxygen Analyzer Maintenance 5 WARNING: THE SENSOR USED IN THE MODEL 3300TA CON- TAINS AN ELECTROLYTE WHICH INCLUDES SUBSTANCES THAT ARE EXTREMELY HARMFUL IF TOUCHED, SWALLOWED, OR INHALED. AVOID CONTACT WITH ANY FLUID OR POWDER IN OR AROUND THE UNIT. WHAT MAY APPEAR TO BE PLAIN WATER COULD CONTAIN ONE OF THESE TOXIC SUBSTANCES. -

6. Reconnect the cell block electrical connector plug. 5.2.5 Cell Warranty Conditions The B-2C Class Micro-Fuel cell is used in the Model 3300TA. These cells are warranted for 6 months, with an expected life of 8 months from the date of shipment (under specified operating conditions—see Appendix). - Page 35 If it is determined that failure is due to faulty workmanship or material, the cell will be replaced at no cost to you. Note: Evidence of damage due to tampering or mishandling will render the cell warranty null and void. Teledyne Analytical Instruments...
