World Premiere at FoodTech Fair: HBM leads the way with the new digital load cell FIT7A

Load cells are no longer just used in large food processing plants. Over the past 60 years, HBM has developed strain gauge load cells that are fast, accurate, small and economical - they can now be used in new areas of food production. Today, load cells are used in many steps throughout the food production process; from chickens hatching and the feeding and milking of cows, to the packing and shipping of meat and dairy products to supermarkets.

HBM has become a key player in the food industry and therefore chose to launch their brand new digital load cell, FIT7A, at Northern Europe's largest FoodTech fair in Herning, Denmark. The three day fair was well attended by 8,300 guests, who were shown everything from checkweighers with integrated HBM load cells to finished dairy products. HBM chose to present their brand new load cell in Denmark’s growing food production industry.

Danish agriculture and the Danish food sector is one of Denmark's largest export industries, with a total export value of 20 billion Euros. In addition, significant exports of derivative products such as agricultural machinery, equipment and technology for agriculture and food production are also included to the export value.

Product and application manager from Darmstadt, Germany, Bernd Knöll visited Denmark to hear customer responses to the new load cell FIT7A. He had the Danish sales engineer Henrik Bache Jensen, who works at HBM's Danish headquarters to help him, and the following section explains what they discovered.

Versatility is key

FIT7A's new digital technology has higher precision and can perform accurate measurements under temperature fluctuations and in dynamic applications.

“Weighing processes can result in bottlenecks which can affect the production rate. To prevent this, HBM focuses on intelligent software and correct weight in the first weighing - also of dynamic applications,” says Danish sales engineer Henrik Bache Jensen. “For example, FIT7A is approved by OIML R60accuracy class up to C4 and up to y = 20000, which means a maximum of 0.5 g deviation at a load cell with total capacity of 10 kg. This was specially developed to address these bottlenecks and still be easy to fit in machine design and maintenance.”

“FIT7A's new digital technology has higher precision and can perform accurate measurements under temperature fluctuations and in dynamic applications. This means, the load cells can be installed on multiple production machines in various production environments,” states Bernd Knöll. Bernd has been involved in the development of the FIT load cells and also in the development of the aseptic load cells in stainless steel specifically for the food industry.

“Previous load cells in strain gauge technology could handle up to 100 weighings per minute, but with the new technology in the FIT7A, it is now possible to do 180 weighings per minute or more if less accuracy is tolerated,” says Bernd Knöll. “This increases production speed, which can lower production costs per unit produced.

HBM expects to see FIT7A used in new production-contexts where it can replace other types of load cells, including load cells in flow measurement applications. Possible new areas could be in the pharmaceutical industry as well as in filling / dosing applications that require high precision and high speed.

Future of food

PW27 hygienic load cell

In addition to the newly developed load cell, HBM also showed their product line specially developed for the food industry. One of these load cells is the analog strain gauge load cell PW27.

The advantage of PW27 is that it can be cleaned to aseptic degree and has an IP69K approval. This means that it has received the EHEDG certification and it can withstand high pressure cleaning as the only one in its capacity class. However, it is still analog which means in order for the load cell to be able to communicate with the other components or processes in the production line, it has to be connected to an external amplifier such as the new PAD4000 digital amplifier in IP68/IP69K protection class, provided by its rugged hermetically sealed stainless steel tube housing.

The Danish and international participants at the fair all welcomed the FIT7A load cell.
“Overall the fair was a success. Many attendants inquired more information about the FIT7A and how they can use it in their operations, production and packaging,” concludes Henrik Bache Jensen.
