Summation Boxes

Sumation boxes allow you to sum the signal from multiple load cells. They come in various capacities, depending on the number of load cells you wish to sum. They also come in various sizes depending on how much room you have to work with -- larger sum boxes are easier to work with but sometimes on-site space restrictions can limit their use. Summation boxes can also come with or without trim pots. Trim pots allow you to make slight adjustments to each load cell's output which allows you to fine tune each load cell's performance in relation to the others. Trim pots are mainly used in legal for trade applications.
