Weight detection circuit for a load cell scale |
摘要 |
A weight detection circuit for a load cell scale which connects an operational amplifier directly to an-output of a bridge circuit of a load cell so as to simplify a conventional differential amplifier, thereby enabling simplification of the overall weight detection circuit to result in a reduction in manufacturing cost. Furthermore, a bias resistance is connected directly to the bridge circuit for the load cell thereby also to simplify the bias circuit to lead to a further reduction in manufacturing cost.
