Mini Force Sensor

Mini force sensor is a small size, low height, fully sealed force sensing device. It is suitable for space limited occasions, generally used in high-precision small-scale weighing occasions, with good anti-side, torsion, anti-partial performance.

1. The composition:

The mini force sensor consists of one or more bridge bodies (such as a Wheatstone bridge) consisting of an elastomer capable of deforming after force and a resistance strain gauge capable of sensing this deformation, and a resistance strain gauge Fixed adhesion on the elastic body and can transmit the amount of adhesive force sensor and the protection of electronic circuit sealant and other three parts of the composition of the force sensor.

2. The work process:

After the external force sensor is subjected to external force, the strain gauge which is affixed to the elastic body is deformed to cause the resistance to change. The change of the resistance causes the loss of the composition of the Wheatstone bridge to output a power electric signal which is linearly proportional to the external force.

1.     Features: 1) small size; 2) low height; 3) fully sealed.

2.     The application: micro-force sensor for space limited force, widely used in industrial, scientific research and other fields.
