Why Interface Load Cells Stand Out from the Competition
As you might expect, there’s a lot of care and attention to detail in our product development methods that allow Interface to create the most accurate and reliable force measurement tools on the market. Honed over our 51 plus years in the manufacturing of force measurement products, we have among the most refined and thorough processes in the industry. Today, we are going to reveal one of the unique testing processes in our LowProfile® load cell development which sets us apart from the competition, by a landslide!
It’s no secret, Interface LowProfile load cells are reliable and offer repeatable results. What isn’t widely known is this is because of the product’s overall capability to handle loads with minimum error due to misalignment. In plain English, these load cells are very forgiving to general misalignment when they are installed into the application. Why? Because of a process called moment compensation. This is one of the primary differentiators from other pancake load cells in the marketplace.
Moment compensation is one of the many production tests we run on our LowProfile load cells to guarantee minimal influence from off-axis loads known as “moments.” We compensate for moments by hanging a weight from a fixture and rotating it around the LowProfile load cell. The offset weights go around and take readings at specific locations. The computer records the data and identifies the highest readings and locations. The operator then modifies the geometry of the material from the beam to make the beamless stiff. Once this process is completed, we go around and repeat the process to confirm results until the product passes the specification criteria.
Moment compensation is performed on every individual Interface LowProfile load cell and most other Interface load cell models to ensure repeatability and accuracy. This is a big deal in the force measurement industry because most load cell manufacturers don’t test and compensate or have a specification for eccentric load sensitivity like we do.
Interface takes these extra steps because we understand that as product development becomes more complex, the margin for error gets smaller and smaller. Moment compensation also helps to maximize the operating life and minimize performance errors. With Interface LowProfile load cells, customers know that every step in our design and development process is conducted to ensure the premium quality which exceeds their needs and quality expectations.
