Dongguan Haibo Sensor weighing sensors need proper selection to unleash their optimal performance. The selection involves comprehensive considerations of structural form, quantity, range, measurement accuracy, and operating environment.

 

1. Structural Form of Weighing Sensor

 

Choose a sensor based on the structure of the weighing device and the sensor's installation position. Common structural forms include cantilever beam, corrugated pipe, single point, S-type tension-compression, column type, spoke type, axle type, etc.

 

2. II. Quantity and Range Selection of Weighing Sensors

 

Typically, use as many sensors as there are support points on the scale body. However, for special scales like electronic crane scales, only one sensor can be used. The selection of sensor quantity and range depends on factors such as the scale's maximum weighing value, the number of sensors used, the self-weight of the scale body, and potential maximum offset and dynamic load.

 

3. III. Measurement Accuracy Requirements

 

Consider accuracy levels, including non-linearity, creep, creep recovery, hysteresis, repeatability, sensitivity, etc. While pursuing high-grade sensors, balance accuracy requirements for electronic scales with cost considerations.

 

4. IV. Operating Environment of Weighing Sensors

 

Corrosive Environment: Choose sensors with good corrosion resistance, such as those with sprayed or stainless steel outer surfaces.

 

Temperature: Select sensors based on temperature requirements, especially for high-temperature environments. Use high-temperature-resistant sensors, and consider insulation or cooling devices.

 

Dust and Humidity: Choose highly sealed weighing sensors. Sealing methods include filling or coating with sealing glue, rubber pad mechanical fastening, welding (argon arc welding, plasma welding), and vacuum-nitrogen filling.

 

Electromagnetic Interference: Opt for weighing sensors with excellent anti-electromagnetic interference performance.

 

Flammable and Explosive Environments: Use weighing sensors that meet corresponding explosion-proof ratings.

 

5. V. Meeting the Accuracy Requirements of the Entire Electronic Scale

 

In selecting weighing sensors, ensure their accuracy slightly exceeds the theoretical calculated value, considering factors like scale body strength, instrument performance, and the harsh working environment.
