Several typical sensor installations
Vertical filling tank
For homogeneous objects such as liquids and bulk goods, it is possible to have two fixed bases and one sensor configuration. The condition is that the capacity structure is symmetrical and the center of gravity of the filling is approximately on a vertical line throughout the filling process. In other cases, especially at higher accuracy, three or more sensors must be equipped.
Rigid mounting of the sensor
This simple rigid mounting of the sensor on the load-bearing body is generally not recommended. This configuration does not allow the sensor to avoid measurement errors due to variations in loading conditions, vibrations, and temperature variations.
Vertical tank container with two supports and one sensor
This measuring system uses a pendulum sensor and two fixed supports, which also serve as a fixed vertical tank container. This low-cost structure allows the sensor to avoid certain measurement errors.
Vertical canister container supported on three or four sensors
Accurate loading conditions mostly use three sensors as measuring elements, however a four-point configuration is also visible in a right-angled symmetrical configuration, although this arrangement is not optimal in principle due to its ultra-freedom and price, but another On the one hand they are easily thought of by the designer. Although the double rocker elastic support does not require a guide rod, most need to be combined with a fixed limiter. For particularly tall vertical cans, additional guides are required in the upper part. In the illustration, the clubs are preloaded with a small preload. In this position, the fixed bar can touch the canister as long as it is inevitably misplaced, thereby causing additional forces by contact friction. Rolling or rope guides are generally not recommended here.
Use vertical tanks on three different weighing modules
The three weighing modules have a guide rod that is cut outside the outer edge of the structure so that the tank does not require other measures and remains horizontally stable. It also has anti-lift protection to prevent the cans from tipping over. This does not require a lot of structural details in the open-air construction. This illustration shows the weighing modules for small, medium and large loads. The use of standard weigh modules simplifies the structure and saves on the cost of the structure, but must take into account the parallelism of the bearing surfaces, the height alignment and so on.
Applying a vertical rim with a rim on the weighing module
In practice, it is generally found that the outer casing of the circular vertical tank generally reaches the bottom to ensure the stability of the entire structure, and a special installation method is required to properly mount the sensor. Figure 12 shows the principle of this structure measured with a sensor, by which it introduces weight into the sensor. Of course, the weighing module also contains lift protection (not shown in Figure 12 for clarity). Even a small lift of the structure is sufficient to introduce the entire weight into the sensor. Therefore, a circular seal is required to seal in this configuration, which is very soft enough to create additional forces.
Rectangular warehouse for loading stations with four sensors installed
At the loading station, vibrations from the conveying mechanism, loading and unloading equipment, and when the weighing chamber is part of the movable equipment, the rectangular chamber is unstable due to the influence of acceleration, which does not consider bulk mass in bulk. When the object is dropped into the bin, it passes through the extreme lateral force caused by falling on the inclined side. In this case, it is particularly necessary to consider the stable guide rod fixing of the preload force in advance. Sometimes the scale container is held fixed when no weighing is required and is only free when weighing. The right-angled symmetrical structure is extremely stable and is therefore also adopted in most sensor installations. At the same time, the sensor generally has an elastic support, such as a pendulum sensor.
