Detailed overview of DE-CONscrew and Siwarex FTC

The following table gives you a comprehensive overview of the different or similar features of the DE-CONscrew and Siwarex FTC controllers for loss-in-weight feeders.

What are loss-in-weight feeders?

Loss-in-weight feeders are measuring devices that are used in many industrial processes to enable the accurate dosing of raw materials. These scales work on the principle of differential weight measurement and can deliver extremely precise results. They usually consist of one or more weighing hoppers, which are filled with the material to be dosed, and load cells that continuously record the weight changes throughout the dosing process. The data is transmitted to a control unit, which monitors and regulates the precise dosing of the material. Loss-in-weight feeders are often used in the chemical, pharmaceutical and food industries, where the precise composition of substances is essential. Their use ensures efficient and accurate dosing and helps to improve product quality and prevent material loss.

 

The function of the control unit for loss-in-weight feeders

The control system of a loss-in-weight feeder plays a crucial role in the correct dosing of the raw material. It monitors and regulates the entire dosing process to ensure that the desired amount of material is dispensed precisely. To do this, the control system continuously evaluates the data from load cells that record every change in the weight of the dosing system. This information is then used to determine the actuating variable of the dosing unit, which is used to control the required quantity of material to be dosed. At the same time, the filling of the dosing container is controlled by activating the corresponding refill units.
Otherwise, the control system continuously monitors the entire dosing process and can make adjustments to correct any deviations. In this way, the control system guarantees accurate dosing of the raw material and ensures efficient and high-quality production.

In the following overview, we take a closer look at the key features of the two control systems DE-CON and Siwarex.
