What is a Load Sensor?

A load sensor, also called a load cell, is a transducer that converts force or weight into an electrical signal. Combined with an amplifier and microcontroller, load sensors enable smart systems, including digital scales, feeders, and industrial automation.

Common Load Sensor Types:

• Strain Gauge Load Cells – Most widely used for precision applications.

• Shear Beam Load Cells – Industrial hoppers and heavy platforms.

• Single-Point Load Cells – Small scales or DIY projects.

• Hydraulic Load Cells – High-capacity industrial systems.
