Weighfeeder JesBelt A

– approved weighing of edible fish….

At Eurobaltic in Rügen Germany, they wished to weigh edible herrings directly from cutter and subsequently invoice the amount weighed. Eurobaltic required a weighing accuracy of +/-0.5%. As the fish came directly from the cutter, it was also very important that the amount of water weighed with the fish, was reduced considerably. Also it was important that Eurobaltic could monitor how many kg were sent into the factory. Further, the weight control had to send a signal to the superior system through a profibus.

The weigher was to be approved according to the existing regulations for purchase and sale, and as to OIML R-50 and PTB (the German national metrology institute for scientific and technical services). Eurobaltic urged Jesma to lead the dialogue with the German Metrology Institute in Rostock ”Eichamt Rostock”, so that the running-in and the approval of the weigher was controlled by Jesma technicians.

Jesma suggested implementing a Jesbelt A weigh feeder. To avoid weighing to much water along with the fish, a draining belt was inserted, where the fish could leave extra water before the actual weighing. The weighers were connected to a 1.5 m long display, which was mounted on the quay where the cutters called in. The Jesma WC9604 weighing computer made it possible for Eurobaltic – via a profibus - to get access to all the weighing data from the weighing computer.
