Phidgets Button Load Cell (0-1000kg) - CZL204 3141_0
A load cell is a force sensing module - a carefully designed metal structure, with small elements called strain gauges mounted in precise locations on the structure. Load cells are designed to measure a specific type of force, and ignore other forces being applied. The electrical signal output by the load cell is very small and requires specialized amplification. Fortunately, Phidget Bridge Interfaces will perform all the amplification and measurement of the electrical output, see under Connection & Compatibility for details.
This Button Load Cell is used in heavy applications. The bottom of the load cell can be bolted to a surface, and force applied to the button on the top. By loading only the button, which is slightly rounded, the load cell is less sensitive to errors resulting from the load not pushing down exactly straight on the load cell.
Connection
Load cells require a power source and produce a very small voltage differential when under strain. In order to read this signal, an amplifier or a board with a high-precision analog-to-digital converter is required. For more details and a list of Phidgets that will connect to this load cell, see under Connection & Compatibility.
Warning
Make sure to calibrate your load cell before using it. You should also have a look at the User Guide for the bridge interface board that you're using to read the load cells.
Connection & Compatibility
Bridge Interfaces
Load cells and strain gauges produce a very tiny voltage differential and must be read by a high-resolution analog-to-digital converter. You can connect this load cell to a bridge interface.
