3137 - Button Load Cell (0-200kg) - CZL204E, 3137


This load cell measures compressive forces of up to 200kg and connects to a bridge input.


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 force and ignore other forces being applied, this load cell is designed to measure compression. 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.

This Button Load Cell is used in applications that require a thin form factor. The bottom of the load cell is bolted, 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.


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.


warning Make sure to calibrate your load cell before using it. You can find information on how to calibrate the cell in the Load Cell Primer. You should also have a look at the User Guide for the bridge interface board that you're using to read the load cells.

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 as described in this table:
