Parallel Beam Load Cell Flexible Structure

 Parallel Beam Load Cell: 

    The load between the load points of the sensor, including between the object and the device and its bearing surface, Parallel Beam Load Cell to pay special attention to not be used in the direction of the load loader and its bearing surface between, does not act in the measurement direction The load component will cause the measurement error and may also shorten the life of the sensor.

    The sensor is only intended for the specified load direction. For example:our model QH-23,QH-22 and QH-21B, the load direction is indicated by an arrow.

    Load-bearing base which does not deform under load. In order to reliably transfer a uniform load from the bottom of the sensor to the base, the sensor must be secured to a solid base, especially for plane-supported sensors.The sensor base must be able to withstand the load corresponding to the load.

    Despite the overall stability, sometimes the base under the load can also be a strong deformation. Since this deformation can cause the settlement of the bearing surface at the same time, it is necessary in this case to keep the settlement size of all the bases equal to avoid the inclination and the resulting lateral force. In general, the rigid structure of the base is better than the flexible structure, soft structure throughout the difficult to achieve uniform subsidence, and will cause the entire structure of the additional stress.

    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 the installation of specific accessories depending on the application. However, in the final analysis, only the design engineers weighing the weighing technology can determine the interference in the measurement process. So the different sensor structure,not only a wide range of load introduction, there are a variety of options to install accessories.

    Typical elastomeric supports are many 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 upper support plate can 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, the return force is generated in the translation, so that the container is back to the starting point,which is independent of the load, and is proportional to the translation distance, according to the elastic support model of up to 800 Newton, this support can balance tilt up to 1.7 ° Of the container.

     In particular, it is advantageous to impinge on the impacted load vibration and other external vibration and elastic support. In addition, the elastic 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 standard beam sensor and C series sensors with pendulum support and swing bearing can achieve self-homing performance, which makes it possible to manufacture high-precision container scales. Pendulum bearing the structure, can reach 3 ° offset without obvious error, Parallel Beam Load Cell the horizontal displacement of the support point can be limited to a certain range.
