Commentary
A highly sensitive electronic needle pressure meter that uses the piezoresistance effect that changes electrical resistance when stress (needle pressure) is applied.
High accuracy is achieved by electronic control using two semiconductor stress elements (semi-conductor stain gauge) and two transistors.
The needle pressure value is directly read by a large meter.
