Therefore by carefully combining a magnetic field gradient and a temperature gradient with the TMO2 transmitter measuring cell an oxygen containing gas can be made to flow creating magnetic wind The intensity of this induced flow depends on the concentrations of oxygen in the sample The TMO2 Transmitter In the TMO2 transmitter measuring cell permanent magnets are used Oxygen Measurement to create a magnetic field The temperature within the measuring cell Bridge is controlled to a constant 113 45 C to maintain thermal equilibrium The cell also contains two pairs of thermistors with one thermistor of each pair located within the magnetic field Since the thermistors are electrically heated a temperature gradient is created within the magnetic field When a small sample of oxygen containing gas diffuses into the measuring cell it is attracted to the field causing the sample pressure to become locally higher The sample pressure is slightly lower in the vicinity of the thermistors because the gas is less strongly attracted at higher termperatures This difference in sample pressure causes the gas to flow out from the center of the magnetic field and over the thermistors The inner wind generating thermistors decrease in temperature as they lose heat to the magnetic wind while the outer wind receiving thermistors increase in temperature as they pick up heat from the magnetic wind The thermistor pairs are additively connected in an
