## Single strain
|
|
|
|
|
|
|
|
Individual strain consists of two 1k resistors connected as a voltage
|
|
|
|
divider. Connection with two fixed 1k resistors as a voltage divider
|
|
|
|
creates a full bridge. **50kg max.**

## Double strain
|
|
|
|
|
|
|
|
Using two single strain half bridges together forms a full bridge. **100kg
|
|
|
|
max.**

## Quadruple strain
|
|
|
|
|
|
|
|
Using four single strain half bridges together again forms a full bridge,
|
|
|
|
with the resistance doubled. **200kg max.**
