Parallel Beam Load Cell Extensive Load Introduction

When weighing containers or monitoring the filling state, the horizontal movement of the containers and brackets due to temperature changes must be taken into account.Rigid mounting accessories prevent this movement and eventually produce horizontal lateral forces, resulting in measurement errors. This force sometimes causes the sensor to be damaged or even completely broken. This may occur at the load loading point, where the eccentric load or the oblique load may produce torque and lateral forces, so the structure of the horizontal force to avoid temperature deformation or other factors is chosen.

The use of mounting accessories to assemble the sensor's criteria is to eliminate a wide range of interference. And therefore require specific installation accessories depending on the application. However, in the final analysis, only the weighing engineers know the design engineers to determine the measurement process of interference. So the different sensor structure, not only a wide range of load introduction,there are a variety of options for the installation of accessories.

A typical elastomeric support is a plurality of overlapping plates and layers that are interconnected by a vulcanization process. A small force also moves the top and bottom load guides in parallel. So the top support plate to avoid lateral force, and not to the sensor under the support plate additional force. The horizontal translation between the container and the sensor can be up to 15 mm. At the same time, in the translation of the return force, so that the container back to the starting point,the force has nothing to do with the load, and is proportional to the translation distance, depending on the elastic support model up to 800 Newton, this support can balance tilt up to 1.7 ° Of the container.

In particular, the damping effect of the impact load on the impact load and other external vibration and elastic support is advantageous. In addition, the elastomeric support is designed to be well insulated and its layered structure minimizes the heat transfer between the container and the sensor. To limit the lateral offset, as long as the endpoint offset protection is set, the parts are not required to be operated.

The loading point in the displacement is slightly increased relative to the starting point. Resulting in the return force, the return force to the system back to the initial state,so put bearing and swing bearing seat can be seen as self-owned.
