New Digital Load Cells for Packaging Machines Provide High Performance of EFC Sensors at 60 Percent Less Cost

HBM , Inc. has introduced its FIT7A digital load cell. The FIT7A load cell not only provides nearly the same speed and accuracy of Electromagnetic Force Restoration (EFR) sensors normally found in modern packaging machines, but it does so at 60 percent less cost. This new strain gauge-based load cell makes it possible to develop completely new machine types and will allow OEMs to serve new market segments.

For example, FIT7A load cells are a perfect fit for sorting weighers and checkweighers used in the food industry. These load cells will help manufacturers package products quickly with the lowest possible amount of overfilling. With the FIT7A, machines can make up to 180 weighings per minute, more than any competing weight sensor.

The FIT7A is as accurate as it is fast. It has an accuracy class C4 per OIML R60 and a maximum scale interval factor Y of up to 25,000 in legal for trade applications. However, in non-legal for trade applications where the value is extremely low, a Tco of less than 40ppm/10k is guaranteed.

Because the FIT7A is a digital sensor, it is easily configurable and offers many signal conditioning functions. The PanelX HBM software provides support for the configuration process with an intuitive user interface. In addition, the FIT7A enables signal analysis and adjustment of the digital filters to effectively suppress all kinds of interference. Other key features include a dosing mode, four limit value switches, trigger mode (external or level), and an IP66 rating.
