When weighing the container or monitoring the fill state, the horizontal movement of the container and bracket resulting from the temperature change must be considered.Rigid mounting attachments prevent this movement, resulting in a horizontal lateral force resulting in measurement errors. This force sometimes causes the sensor to be damaged or even completely fractured.This may occur at load-loading points where eccentric or oblique loads may produce torsion and lateral forces, thus selecting a structure that avoids the horizontal forces caused by temperature distortions or other factors.
The use of mounting attachments to assemble sensors is a rule that eliminates many aspects of interference. Therefore, depending on the application, it is required to choose the specific installation attachment.In the final analysis, however, only design engineers with symmetrical weight technology can determine the interference in the measurement process. Therefore, for different sensor structures,there is not only a wide range of load-import methods, but also a variety of installation accessories selection.
The typical elastic supports are many overlapping plates and layers, which are interconnected through the vulcanization process. A small force also moves the upper and lower load guide planes parallel. Therefore, the top support plate can avoid lateral force, without attaching the support plate to the sensor. The horizontal translation between the container and the sensor is up to 15mm. At the same time,in the translation of the recovery force, so that the container back to the starting point, this force is not related to the load, but proportional to the translation distance, according to the elastic support model of the different models can reach 800 newtons,this support can balance the tilt up to 1.7 ° container.
In particular, the impact of the load vibration and other external-induced vibration, elastic support of the damping effect is advantageous. In addition,the elastic support body is designed to be well insulated, and its layered structure makes the heat conduction between the container and the sensor very small. To limit the side offset, set the endpoint offset protection without having to manipulate the part.
Note: Since the container connection pipe makes the elastomer support at a nominal load of about a mm, this is significantly larger than the actual deformation of the sensor,if not considered will produce large errors.
Although the center of gravity is unstable, it is necessary to ensure that the container is firmly fixed. In the field of container weighing, the elastic support is a low-cost and simple component which can meet the requirement of low precision.
This is a sensor designed to return to the starting point independently of the weight-loaded eccentricity, which utilizes the physical characteristics of the stable balance. Load Cell As the sensor of the swing body occupies the load guide surface, its curvature radius is larger than the sensor height. The swing of the initial bit causes the load point to rise, thus making the sensor return.
