The use of reactor weighing module

Detailed introduction of weighing module

Weighing modules are divided into two types in practical applications: static load weighing module and dynamic load weighing module. The static load weighing module is suitable for occasions where only vertical force is applied. Such as the weight detection of reactors, tanks and storage hoppers. The dynamic load module is suitable for occasions with obvious force. Such as platform, production line, conveyor belt weight detection
Precautions for weighing module selection

⑴The selection of electronic weighing module is generally based on the support point of the container to choose the range of 3 or 4 modules. Due to the weight of the scale body (container), vibration impact, partial load and other factors, generally Choose according to the following rules. Multi-sensor static weighing system:
Fixed load (weighing platform, container, etc.) + variable load (load to be weighed) ≤ the rated load of the selected sensor × the number of sensors × 70%, of which the 70% coefficient is added considering vibration, shock, and partial load of.

⑵Precautions for installation
Weighing modules should be adjusted horizontally, including the installation plane of a single module and the horizontal adjustment between a set of weighing modules.

The sensor cannot pass current during welding. When welding the top plate, the ground wire should be connected to the scale body, and when welding the bottom plate, the ground wire should be connected to the foundation to prevent damage to the sensor.

If the weighing module has a conveying pipe on the scale body, it should be replaced with a hose, or the connecting pipe should be as long as possible to prevent them from eating the real load of the sensor and causing errors.

It is necessary to weld a weight calibration station on the container for calibration. Generally, there is no place for weights to be placed on the container, and it is necessary to weld a platform to place the weights. Usually welded under the container to facilitate the placement of weights up and down.

The junction box must be protected from moisture, and the excess holes should be plugged with sealing plugs. If the junction box is installed outdoors, a protective box must be added to prevent rain. In use, the junction box is damp and cause failures from time to time, so sufficient attention must be paid.

⑶ Notes for debugging:

Before debugging the weighing module, be sure to check whether the nut on the top of the support screw of each weighing module has been loosened and whether the sleeve is in a free state, otherwise, large errors will occur and even weighing cannot be performed.

When debugging, check whether the factory setting value of each parameter meets the actual needs, especially the "reset at power-on" parameter, which is generally set to "automatically clear at power-on" at the factory, and it is changed to "prohibited" on the container scale. Automatic reset on startup" to prevent the material weight of the container from being reset to zero and lost due to power failure and other reasons.

The range setting does not refer to the rated total load of a set of weighing modules, nor does it include the weight of the container itself, but should be weighed according to the ^large material, and select greater than or equal to ^large scale from the number of divisions and division values given in the manual The weight is used as the range.

The power supply voltage of the weighing indicator must meet the requirements. If the voltage is unstable and exceeds the allowable range, it will cause digital drift. ^Use a regulated power supply.
Since the weighing system composed of weighing modules is easy to realize process automation weighing and is easy to network with computers, it will be more and more widely used in chemical enterprises.
