Important technical indicators:
Repeatability: the sensor maintains the consistency of the data for the same amount of force applied. In general, we recommend testing or calibration by adapting the sensors to "training"
Linearity: refers to the sensor's response to the load offset more than the actual range of the sensor. The calibration can keep the output linear as much as possible
Hysteresis: the difference in the actual output value of the sensor when the load is added and the load is removed. In static state, the hysteresis is very small when the load increases. But when the load is small for a long time, there will be errors caused by hysteresis
Drift: when the force is applied for a period of time, the output changes accordingly. If the output resistance continues to decrease under a fixed load, the output will slowly increase. On time, considering the factors of drift, it can reduce its influence. The easiest way is to ensure that the calibration is consistent with the actual test time period
Temperature sensitivity: normally, the output varies with the temperature at high loads. To ensure accuracy, maintain consistent temperature during calibration and testing. If inconsistent, it is best to make a calibration at different temperatures, and to preserve the standby
Life span: it depends on how you use it. General sensors can be used over and over again, except in some extreme cases, such as hard edges or shocks. After testing, the motion film pressure sensor can be used one million times. Physical damage will naturally decrease its life. Keep the sensor area clean, or dirt will cause inaccurate measurements and premature saturation |
