Product Features

This small load cell measures shear forces of up to 100g and connects to a bridge input.
Product Description

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, the 1046 PhidgetBridge will perform all the amplification and measurement of the electrical output.

Load cells are designed to measure force in one direction. They will often measure force in other directions, but the sensor sensitivity will be different, since parts of the load cell operating under compression are now in tension, and vice versa.

This Single Point Load Cell is often used in small, high-precision scales. It’s mounted by bolting down the end of the load cell where the wires are attached, and applying force on the other end. Where the force is applied is not critical, as this load cell measures a shearing effect on the beam, not the bending of the beam. If you mount a small platform on the load cell, as would be done in a small scale, this load cell provides accurate readings regardless of the position of the load on the platform.


The 3139 connects to a bridge on the 1046 – PhidgetBridge 4-Input


The following table shows how to connect the Load Cell Wires to the bridge connectors.
