LFP-10

Weighing load cell’ structural features

1.Core structure: It adopts parallel beam structure,where the elastic body of the sensor consists of two or more parallel beam-like structures. When subjected to force, the beam body undergoes slight deformation.Strain gauges attached to the beams convert this deformation into electrical signals to realize weight measurement.

2.Structural Advantages: The design of parallel beams ensures a clear and uniform force transmission path,which can effectively convert vertical weight loads into bending deformation of the beams,making it easy for the strain gauge to accurately capture the signal, laying the foundation for high-precision measurement.

Technical features

1.High precision:The parallel beam structure has good force transmission stability. Combined with high-precision strain gauges and signal processing circuits, it can achieve accurate measurement of tiny weights, especially in small-range scenarios.

2.Strong anti-eccentric load capability: The symmetrical structure of the parallel beam can to a certain extent,offset the measurement error caused by the offset of the weight placement position (eccentric load), ensuring the measurement accuracy can still be maintained when the load is slightly offset.

3.Range Characteristics: The range can be less than 50g, making it a typical small-range weighing sensor. It is very suitable for micro-weight weighing scenarios, such as laboratory precision weighing, small material quantitative filling, electronic balance core components, etc.

4.Dynamic response and application: The dynamic response frequency is less than 100Hz, and is mostly used for static testing.
