Checkweighing according to OIML


Especially in the food industry, checkweighers make a significant contribution to product quality since the accuracy of the quantity specified on a package can only be guaranteed in this manner.

In addition to the mechanical design, the weighing electronics is of decisive significance. The SIWAREX FTA and SIWAREX WP231 from Siemens provides fast, high-resolution electronics which is highly suitable for use in static checkweighers. As a component of the SIMATIC automation system, integrated control of the complete checkweigher presents no problem, i.e. covering the drive, image processing or implementation of the HMI.
