Trace Oxygen Analyzer Operational Theory Operational Theory 2.1 Introduction The analyzer is composed of three subsystems: 1. Analysis unit with zirconium oxide sensor(s) 2. Control unit with signal processing, display and controls 3. Interface unit, supplying signals between 1 and 2. The analysis unit is designed to accept the sample gas and direct it to the sensitive surface of the zirconium oxide sensor. The control unit processes the sensor output and translates it into an e

Operational Theory Model 3300ZB The sensor is designed for long term stability with an operating life of 5 years. This unit features one or two sensors, and can be custom-designed for a specific range of oxygen analysis. 2.2.2 The Effect of Pressure In order to state the amount of oxygen present in the sample as a specific portion of the gas mixture, it is necessary that the sample diffuse into the sensors under constant pressure. If the total pressure increases, the rate that o

Trace Oxygen Analyzer Operational Theory 2.3.2 Signal Processing Figure 2-1 is a block diagram of the signal processing electronics described below. Figure 2-1: Block Diagram of the Signal Processing Electronics In the presence of oxygen, the sensor(s) produce a current. A current to voltage amplifier (I–E AMPL) converts this current to a voltage. The output from the I-E amplifier and subsequent buffer circuit (not shown) is sent to an analog to digital converter (ADC), and

The same digital information is also sent to a 8-bit digital to analog converter (DAC) that produces the 0-10 VDC analog concentration signal and the 0-10 VDC analog range ID output. A current to voltage converter (E–I CONV) produces the 4-20 mADC analog concentration signal. Teledyne Analytical Instruments 8
