The Oxygen Analyzer is a complete solution consists of the oxygen sensor with all inbuilt electronics and mechanical filter assemblies.
The DX4P-ZrO2 transmitter is a complete solution for fast and accurate oxygen concentration measurements within the range 0...1000 ppm, 0...5%, 0...25% or 0.1...95%. The sensor and the measurement electronics are integrated into a stainless steel transmitter housing. The electronic amplifies the raw sensor signal and the output is a logarithmic current output signal 4...20mA as a function of oxygen partial pressure.
Zirconium oxide, heated to about 450 °C, is penetrable for oxygen ions. A voltage applied to the sensor therefore pumps the oxygen out of the inner chamber. At a constant gas pressure, the quantity of oxygen pumped out is equal to the quantity of oxygen molecules diffusing in through the capillary, and within a certain range it is independent of the voltage applied between the electrodes. The measurement current it proportional to the quantity of oxygen molecules pumped away.
- Regulation of the heating power of the sensor
- Amplification of the microampere signal from the sensor
- Conversion of the amplified signal into a standardized current output signal
