In general you'd be looking at a load cell and some signal conditioning
to do this sort of thing. It's unlikely you'll find a sensor that can be
connected directly to the ADC. Load cells are mechanical arrangements to
spread the load out and strain gauges, which are resistor networks that
shift slightly as the metal under them stretches (the strain) under stress.
They are very low level (thermocouple level) and often people want to
read them to very high resolution and accuracy.
