Web18 mrt. 2024 · Trophy points. 1,393. Activity points. 28,740. The best approach depends greatly on the shape of the core, and the size/type of sensor you have. This is easiest when your core forms closed path (since that confines most of the field to a known path) except for a very small gap, and you sense the field inside that gap. WebTR may be measured at, say, 20% oxygen or 50%RH in which case the calculated P values (which are normalised to 100% of the gas) would be 1/5 or 1/2 of their true values. So you need to enter %TR, the test value, in order to get the right TR from P or the right P from TR. The calculations only work if the thickness units for P are the same as ...
