Where the hell have you been for the last year. Don't you read when we post? There is no secreties on what loadcell we are using. Though we had that said and clear all the time.
We are using a dynamic loadcell (Quartz Crystal Loadcell). In opposite of "Strain" loadcell, which would read constant pressure, which has you press the loadcell further and further, the signal increase. As an exemple, if you press 100 pound on it for an hour, this loadcell will read 100 pounds for a steady period of 1 hour.
Now, a dynamic loadcell (Quartz Crystal) will give you voltages as the pressure goes up (Movement). As soon as you will stop increasing that pressure, even if you stop at 100 pounds, the voltage will drop until it reaches 0 volts. Now, when you will release that pressure down to 0, the voltage will reverse to a negative values and when the pressure is at 0 pound, you will read -100 pound on the display.
A dynamic loadcell is built to reack very fast in time, where your fishscale will ack like a strain loadcell and miss a big portion of the movement or "Blow" since it is too slow.
A Strain loadcell measures constant pressure. A Dynamic loadcell will read movement force, like a hammer blow.
We always said that since day 1 ... I though it was quite clear.
