## Single strain |
|
|
|
|
|
|
|
|
|
Single strain consiss of two 1k resistors voltage divider. Fitting two more |
|
|
|
|
fixed 1k resistors creates a full bridge. 50kg max. |

|
|
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.** |
