Fixed installation of load cell under vibration environment

Friends who are familiar with load cells know that the general installation of load cells is relatively stable. However, there are some problems in real applications that the environment in which the sensors are installed is not stable. Some problems such as shaking and vibration may occur. At this time, the stability of the load cell is very important, and in the case of vibration, the linear relationship of the sensor's sensitivity may be partially affected.

It can be said that the installation of the load cell under vibration is more troublesome and difficult to operate, and the output signal error is inevitable. Since the load cell is originally a device that converts force into voltage or current in real time, changes in external force directly affect the output signal. At this time, the error of the sensor is not only a problem of the performance characteristics of the sensor itself, but also a very important problem is the installation problem.

The stability of the load cell used in a vibrating environment is higher than that of ordinary ones. The sensor that is less affected by the external environment needs to be selected. Of course, it is also necessary to pay attention to that the load cell terminal must have good fixability to prevent Changes in force in a vibration environment cause problems such as poor contact. In understanding the fixity of the terminal block, the first thing we should pay attention to is the fixity of the entire load cell. Of course, in the vibration outside world, what we mean by fixing is only relative fixing. Only when the whole sensor is fixed can the stability of data signal transmission be maintained. Choose different installation methods for different environments. Before purchasing, technicians need to test the stability of the installation platform, and then communicate with the manufacturer. The manufacturer recommends which load cell to choose and how to install the sensor to greatly reduce the sensor error .
