Danfoss pressure sensors have been used in the medical industry for a long time. Danfoss pressure sensors were considered for application in the medical industry since their inception. In recent years, with the further improvement of Danfoss pressure sensor performance, their application in the medical industry has also been well developed. With the use of new technologies and materials, the performance and stability of Danfoss pressure sensors will be better developed, and the development of Danfoss pressure sensors in the medical industry will also be further improved. Now, countries are investing a lot of manpower and funds to open up and develop medical Danfoss pressure sensors.
We are choosingDanfoss pressure sensorWhen we need to consider its comprehensive accuracy, what factors can cause errors in the accuracy of Danfoss pressure sensors? There are actually many factors that can cause sensor errors. Below, we will note four inevitable errors, which are the initial errors during the production of Danfoss pressure sensors.
1. Linear error: This is one of the reasons why the initial error of Danfoss pressure sensors is relatively small, and the reason for this error is the physical nonlinearity of the silicon wafer.
2. Offset error: Due to the constant pressure range maintained by Danfoss pressure sensors, changes in laser adjustment correction and transformer diffusion may have offset errors.
3. Lag error: In most cases, the lag error * of Danfoss pressure sensors can be ignored because silicon wafers have high mechanical stiffness. When there is a significant change in pressure, it is necessary to consider the factor of hysteresis error.
4. Sensitivity error: The magnitude of the error generated is proportional to the pressure. If the sensitivity of the device is higher than the normal value, the value of sensitivity error will be an increasing function of pressure. If the sensitivity is lower than the normal value, the numerical difference in sensitivity error will be a decreasing function of pressure. The factors causing this error depend on the changes in the diffusion process.
