Load cell

We use a single point/beam load cell, because the force can be applied anywhere on the platform (here for example on a surface of 200x200 mm).

(Image source: “Single point cells differ from the other cells described thus far in that it is moment insensitive, meaning that it reads the same regardless of where the load is applied to the upper platform. Capacities typically range from 2 lb to 4,500 lb and can accommodate platform sizes up to 48 inches square.”)

Temperature Measurements

Currently done by the ADC (ADS1220), but non-ideal due to self-heating during constant acquisition. Therefore it is better to install an external temperature sensor (ideally measuring outside the case, can be surrounded by heat shrink around the load cell cable).
