Any probe that measures temperature in boiling water system measures also pressure. That is because boiling point of water is directly depended on pressure.
Jouni, you can't see the forest for the trees. Sure, temperature will depend on pressure. But pressure is not being measured by a temperature probe. Rather, if we assume saturated steam and we know the temperate, and it's saturated steam, yes, we can calculate the pressure.
But Galantini measured the temperature and appears to have concluded that a temperature of 100.1 C. or more indicated dry steam. That isn't true if the pressure is elevated only a little. He also claimed that the pressure was "ambient." That was preposterous if this was under conditions of substantial steam generation, pressure would be elevated, and that's been calculated.
Galantini, with the probes he had, could not have measured the pressure inside the chimney, unless he took the probe with pressure measurement (he did not state he used that probe) and took it well beyond its rated temperature.
