The weighing sensor Is it the resolution criterion of destruction

1. Testing characteristic impedance with digital multimeter

If the bridge arm of an inductor is 350 Ω, the input and output impedances should be 350 Ω by using a digital multimeter. Otherwise, it is determined that the sensor is damaged.

2. Zero point test

Generally, the working standard voltage of inductor is 5 ~ 12VDC. Use a digital multimeter to check the output terminal. If the zero point output (without load force) of inductor is within ± is regarded as normal, and if the zero point exceeds ± it is regarded as load damage.

Choose a high quality weighing sensor Weighing sensor (also known as load sensor or converter) is a kind of mechanical equipment for producing and processing metal materials. The bending load is converted into mechanical equipment force into electronic signal. The bending does not exceed the ductility of metal material and is measured by strain gauge bonded on the point module. Is a piece of production processing metal material bending and load of mechanical equipment force and mechanical force into electronic signals. Bending does not exceed the ductility of the metal material and accurately measures the point at which the strain gauge adheres to the rechargeable battery. If the load is released at a moderate position in the load module, the strain gauge will show a proportional electronic signal.

 Taizhou load cell manufacturer

In the important index value of the load cell, will show the accurate net weight information, the content is:

Discrete system: rated output of load cell is ± 0.018%.

Sluggish: rated output of load cell is ± 0.025%.

No net weight: the rated output of load cell is ± 0.01%.

Stress relaxation: load cell rated output ± 0.01% in five minutes.

Temperature hazard to output: ± 0.0008% load per Fahrenheit.

Temperature hazard Zero: ± 0.001% of the rated output of the rechargeable battery per Fahrenheit.

Master the specifications and models: although each specification and model may not be suitable for the installation of your weighing controller, the key is to master each specification and model to determine the comprehensive precision of the weighing sensor.

The inaccuracy is the error between the reading value of the load cell output (i.e., the load from zero without increasing the load or reducing the load from the short-circuit capacity of the load cell) and the natural environment standard under the same load standard. The inaccuracy of the specification model is ± 0.01% than that of the load cell in all categories. Inaccuracy can endanger the accurate measurement of dead weight in all weighing applications. It is able to define the inaccuracy standard under worse conditions according to the added inaccuracy deviation and the composition of the load cell.
