How to choose the overload protection level of load cell?

When selecting the overload protection level of the load cell, the following factors need to be considered.

Application environment: first, evaluate whether there is any situation that may lead to overload in your application environment. For example, in dynamic measurement or applications with shock and vibration, the possibility of overload is high.

Expected maximum load: determine the maximum load that may occur in your application, which should include all potential overload situations, and select a sensor with rated capacity greater than this maximum value.

Safety factor: In order to provide additional safety guarantee, it is usually recommended to choose a sensor that is higher than the actual maximum load by a certain proportion. This ratio depends on the specific needs and safety requirements of the application, and the common safety factor is 1.5 to 3 times.

Overload protection level: different load cells provide different levels of overload protection, and some load cells can bear up to 150% or even higher rated load without causing permanent damage. Please check the product specification to understand the specific overload protection capability of each model.

Balance between cost and performance: Sensors with high overload protection level are usually more expensive. Weigh whether it is worth investing in a higher level of overload protection according to your budget and demand for reliability.

Installation conditions: consider whether the installation mode of the sensor helps to reduce the risk of overload. For example, the impact and vibration can be effectively reduced by using buffers or other damping devices.

Industry standards and regulations: Some industries may have specific standards or regulations that require the use of sensors with specific overload protection capabilities to ensure that the products you choose meet these regulations.

To sum up, when choosing the overload protection level of the load cell, it is necessary to comprehensively consider the specific requirements of the application, the expected working environment and the cost to ensure that the load cell suitable for your project is selected.
