Semiconductor Strain Gauge

Load cell selection: Check the following information in turn to select a suitable load cell or provide detailed information required to design a custom load cell.

Maximum working load: Determine the maximum force that the load cell may receive in actual work and select the range of the load cell based on this;

Loading method: Determine the loading method of the sensor, compression, tension or compression and tension

Unit of measurement: Determine the unit of measurement for weighing, such as kg, N, t, lb, etc., in order to select and match the instrument.

Accuracy: The weighing system requires the accuracy of the load cell. The error calculation is usually the accuracy multiplied by the full range of the load cell.

Temperature: The working temperature of the load cell. If the working environment temperature changes greatly, the load cell needs to be temperature compensated, or the high temperature environment needs to be processed with high temperature.

Overload conditions: whether the load received by the sensor will exceed the maximum range, and how much it will affect our structural design of the load cell

Size requirements: Determine the size requirements of the installed equipment for the load cell.

Signal requirements: what kind of signal the receiving device needs to provide from the load cell: 1.mV signal 2. The converted standard analog signal, such as 4-20mA, 0-10V, etc. 3. Digital signal: RS232 or RS 485, etc., 4. Wireless transmission

Material requirements: Some environments have requirements for the sensor material, such as the use of stainless steel in a corrosive environment to make the load cell

Certification: Determine the identification certificate or qualification certificate required for the load cell

Protection level: determine the waterproof and dustproof level required by the load cell
