IP ratings are typically identified with the nomenclature of “IP” followed two or three characters, for example: IP68 or IP69K. The first character after the IP identifies the level of protection against the ingress of solid foreign objects. The second character identifies the level of protection against moisture/liquids. The third character is a special identifier used to provide additional information related to the protection of the device. A detailed explanation of these codes can be found at IP Code - Wikipedia, the free encyclopedia. Read more about IP69K here

A load cell is a device that is used to measure weight or force. W hen a force is applied to it in a specific manner, a load cell produces an output signal that is proportional to the applied force. One end of a load cell is typically supported on a rigid structure while the other end supports a load-receiving device through which the load or force is applied. Load cells can be used individually or in combinations in weighing devices, as dictated by the geometry of the object to be weighed. Read more about load cells here.

Many manufacturing facilities currently have load cells installed in tank systems that are no longer operational. Most of the times the load cells are left in place and the electrical cables connecting to the controls are simply cut. Production Managers, QC Managers, and maintenance personnel alike have surely encountered “that tank” or “vessel” which never weighed correctly.
