What are the misunderstandings of spoke type load cells that you don't know?

Now for the choice of spoke-type load cells, our first concern is its actual needs and application environment. For example, detecting environmental conditions, and the volume requirements of the object to be measured. In addition, there are signal output methods, whether wired transmission and measurement contact methods are all factors that we need to understand before selecting a sensor. However, there are many misunderstandings in the understanding of some users' symmetric weight sensors. Here are the 2 big mistakes that Ocean Xiaobian explained for you. Remember to collect them~
Myth #1: The higher the sensitivity of the spoke type load cell, the better. In our opinion, the high value sensitivity often means higher work efficiency. However, for the load cell, is this reference indicator correct?
However, we cannot ignore another problem: as the sensitivity of the spoke-type load cell increases, conditions unrelated to the object being measured are introduced more and are continuously amplified as the sensitivity increases. Such a result will eventually have a lot of adverse effects on the accuracy of the measurement. Therefore, high-sensitivity sensors are definitely aspects that we need to pay attention to but cannot be blindly chased.

Moreover, for sensors, their sensitivity is directional. When measured is a single vector, and its directionality has higher requirements, we do not need other sensors with less sensitivity. When the measurement is a multi-dimensional vector, we need to focus on sensing devices with small cross-sensitivity. It can be seen that the sensitivity of the sensor is not necessarily higher as possible.
Technically speaking, only when the sensor maintains a higher sensitivity, the value of the output signal corresponding to the measured change is greater, which may be more advantageous for signal processing. Therefore, from this perspective, the higher the sensitivity of the sensor, the better.


Misunderstanding 2: The greater the accuracy of the sensor, the better the accuracy of the weighing sensor must be selected. For the technical application of sensors, products with higher precision often mean higher prices. Is it only the high-end price to guarantee the needs of our measurement? Or, how can we grasp our needs?
The accuracy of the sensor is another important indicator to judge its characteristics. Accuracy can be said to be an important part of the accuracy and timeliness of the entire measurement system. Therefore, the accuracy of the sensor is also an important aspect that we cannot ignore.
In fact, if our measurement needs are relatively constant, we only need to choose a relatively cheap, repeatable load cell, and not necessarily choose a more expensive high-end product. Of course, if it is for quantitative analysis or has higher measurement requirements, then we must use more precise spoke load cells to meet our application.
Well, the above is a brief introduction of Xiaobian, the little friends who need it are welcome to call us...
