Changes to tinman 2008-11-27The weighing system has changed fundamentally. Instead of measuring the deflection in the beam when it raised the water container, there is now a stiff beam with a counterweight, so the water tank is just overbalanced by the counterweight, even when it is full. A cam raises the back end of the beam to let the water tank fall onto the heat exchanger. For weighing, the cam releases the beam which tilts up to push on a load cell. See the diagram which will soon be added to this page. The precision of weighing is now at least ten times better. The program has been changed because the cam drive is different. The interuppted pulse is now the weighing pulse. The details are documented in the attached pdf. |
