Axial gradient (in N-S direction) and magnetic field (N-S component) are shown--the recorded spikes are in the order of tens nT p-p (even larger for vans/busses); we show that there is a clear correlation of the spikes and car traffic.
Axial gradient of the magnetic field gradient (dB/dL) at the wall of the channel, which caused oxygen transfer towards the pellet surface was equal to 1.56 T/m, but it was not higher than 0.8 T/m in the central part of the flame.
The 9190A with "process" option features 4-20 mA connectors, a reference thermometer input, 4-wire PRT/RTD input with an accuracy of [+ or -]0.02[degrees]C, and a reference sensor control to minimise the effects of the axial gradient when a reference PRT is aligned with short sensors.
