Weigh modules come in many types and configurations and are used in a wide variety of applications. The weigh module sensor can be completely floated from the ground weighbridge or it can be reliably linked directly through the grounding screw on the housing, depending on the customer's use of the weigh module.
Introduction to the grounding operation of the weighing module:
1. In order to meet the requirements of anti-common mode interference, a special grounding pile should be set between the sensor and the earth, and it should be reliably connected with the sensor casing.
2. After the sensor is properly grounded, it not only effectively suppresses the common mode interference introduced by the ground potential change, but also eliminates the interference signal generated on the bridge network due to the influence factors such as the space electromagnetic field and electrostatic induction, because the sensor housing itself is an external one. A shield that protects the electronics of the strain gauges inside the elastomer of the sensor.
3. If there is no interference introduced by the grounding conductor propagation path, for the general weighing module, the weighing sensor and the mounting base are not provided with insulating mats, but directly with the pre-embedded iron or anchor screws of the weighing module. connection.
Factors affecting the accuracy of the weighing module:
Pipeline design and principles are the main factors affecting the accuracy of the weigh module. Any tank scale has a feed discharge pipe. If the pipe is not properly installed, it may cause thrust or tension to the tank, resulting in weighing error. This should be avoided as much as possible in the piping design.
The following guidelines should be followed when designing a piping system:
1. All pipes connected to the tank should be laid horizontally to prevent the tank from being suspended due to the pipeline.
2. Minimize the deflection of the tank scale bracket structure to reduce the deflection of the pipeline.
3. The first connection support point of the pipeline should be placed as far as possible from the tank, which will increase the flexibility of the pipeline. In the case of meeting the process requirements, the smaller the diameter of the pipe, the better the pipe size is, the better, which also increases the flexibility of the pipe.
4. As long as it is possible to use a soft connection.
