While many people may see a scale as all one system, it is really made up of different components with very different jobs. Each of the components is designed and configured to work with the system, providing accurate weights in a wide range of different environments and workplaces.
The Purpose of a Load Cell
A load cell is like the brain of the scale system. It takes the actual force or the change when the object is placed on the platform of the scale and converts it into an electronic signal. That electronic signal is sent from the load cell as a current, voltage or a frequency change. Different types of scale systems will use various types of load cells to provide this function.
The tension load cell is used to measure loads that pull down on the scale rather than by being placed on the scale. When the load is placed on the scale the force measured is compressive in nature which is perhaps the more familiar concept of weight measurement.
Options to Consider
There will be several different options in the tension load cell for consideration with most applications. These includes s-beams, shackle, and link, as well as column styles of load cells.
Regardless of the style or type of tension load cell selected, it will be critical to consider the weight capacity of the system as well as the design of the load cell itself. Since these load cells may be exposed to moisture, humidity, and dust when installed, it will be important to make sure they are sealed and protected for durability.
The more accurate these load cells are, the higher the level of performance and the smaller the downtime for the scale. Look for weightless calibration through software to further decrease downtime and verify accuracy.
