"resistor , mechanical adjustment " That's pretty much the broad definition of a potentiometer. They are not all nice round twiddly knob thingys.
A resistor with a sliding contact is a potentiometer as far as I am concerned.
Are you sure it is a bimetallic strip? That doesn't make sense, as such strips are temperature sensitive, not pressure sensitive. And those gears in there look rather similar to the gears that drive the pointer in a typical bourden pressure gauge.

Ah, this page says the pressure pushes a diaphragm rather than a bourden tube, so I wasn't quite right, though why the lotus one uses gears in there is strange, I would think that reduces reliability.
