1. Advantages of resistance strain gauge load cell.
1.High accuracy and sensitivity: Resistive strain gauges are very sensitive to changes in force and can therefore be used to measure even the smallest forces. At the same time, due to its high accuracy, it is widely used in various occasions that require high-precision force measurement, such as weighing, pressure detection, torque measurement, etc.
2.Good stability: The electrical strain gauge has a wide operating temperature range and can work normally in the temperature range of -50 150. At the same time, its performance is stable, and it is not easy to drift or error after long-term use.
3.High reliability: The structure of the resistance strain gauge is simple and not easy to be damaged. At the same time, its measurement circuit is relatively simple and reliable.
4.Adaptable: The resistance strain gauge can work under various harsh environmental conditions, such as high temperature, low temperature, humidity, vibration, etc.
Second, the shortcomings of resistance strain gauge load cells.
1.Susceptible to temperature: The resistance of the resistance strain gauge is not only affected by external forces, but also by temperature. Therefore, when using strain gauge load cells, measures need to be taken to reduce the influence of temperature on the measurement results.
2.Nonlinearity: There is a nonlinear relationship between the resistance change of the resistance strain gauge and the external force, which can lead to errors in the measurement results.
3.Susceptible to overload or shock: The structure of the resistance strain gauge is fragile and susceptible to overload or shock, resulting in damage or inaccurate measurement results.
3. Tips for using resistance strain gauge load cells.
1.Choose the right resistance strain gauge: Choose the right resistance strain gauge according to the measurement needs, such as range, accuracy, operating temperature range, etc.
2.Proper installation and fixation: When installing the electrical strain gauge, make sure that it fits snugly against the object to be measured, without bubbles or gaps. At the same time, measures should be taken to prevent the effects of overload or shock on the resistance strain gauges.
3.Reduced temperature influence: The influence of temperature on the measurement results can be reduced by using thermostatic measures or temperature compensation techniques. For example, measures such as thermostatic water baths or heaters are used to maintain a stable temperature environment.
4.Elimination of nonlinear effects: Nonlinear effects can be eliminated by linearizing the measurement circuit. For example, measures such as linearization circuits or software compensation techniques are used to reduce nonlinear errors.
5.Regular calibration and maintenance: To ensure the accuracy and reliability of the measurement results, the resistance strain gauge load cell needs to be calibrated and maintained regularly. For example, regularly check the appearance and performance indicators of the sensor to identify and fix potential problems in a timely manner.
