Which type of load cell should be used for weighing in a reaction kettle
Thread Content
The reaction tank is equipped with a stirrer, which causes vibration; what type of load cell should be chosen and how should it be installed? Thank you! I have seen weighing sensors from Mettler installed on the side of the reaction vessel at the site.
For reaction vessels equipped with agitators that generate vibration, shear beam or double beam load cells are recommended. Sensors of this type have high resistance to lateral forces and torque, and are capable of accurately measuring weight even in the presence of vibrations. During installation, it is necessary to fix the load cell at the bottom or side of the reaction vessel, ensuring a secure connection between the sensor and the vessel body. It is recommended to use shock-absorbing pads or elastic elements to reduce the impact of vibrations on the sensors, and to ensure that all sensors are at the same level in order to maintain the accuracy of the weighing data. .
It doesn’t seem like there are any special rules for this, haha
There aren’t any specific rules, but the data you obtain must be accurate
For the brand, Mettler is definitely the top choice. For installation requirements, just check the manufacturer’s documentation – they will recommend many new products as well as various measurement methods to you
Any form is not a big issue; the key is that the connection between the reaction vessels must be a flexible connection
Okay, thank you. I’ll contact the manufacturer right away
Bellows load cell: Advantages: 1. Strong impact resistance. 2. It has a relatively small volume, allowing for flexible installation. 3. It has a certain tolerance to minor vibrations. Disadvantages: 1. The measurement accuracy may be relatively lower. 2. The load-bearing capacity may be lower than that of columns. Column-type load cells: Advantages: 1. High load-bearing capacity, capable of handling heavy loads. 2. It has a robust structure and good stability. 3. The accuracy is reasonably guaranteed. Disadvantages: 1. It may be large in size, requiring significant installation space. 2. The ability to adapt to severe vibrations may be relatively limited. Shear beam type load cell: Advantages: 1. High measurement accuracy. 2. It has good resistance to eccentric loading. 3. It has the ability to adapt to a certain level of vibration. Disadvantages: 1. Relatively more susceptible to external interference. 2. The cost may be high. Double-beam load cell: Advantages: 1. Relatively stable structure. 2. It has good precision performance. 3. It can be applied to various operating conditions. Disadvantages: 1. The installation requirements are relatively high. 2. Prices may be at a high level.
I have used domestic Lijing products, which are available in single-point and multi-point versions. The single-point version works like a scale for lifting, while the multi-point version uses supports placed between the legs and the tank’s padding plates – three or four points in total
