How It Works

The straight bar load cell uses a strain gauge principle. When a weight or force is applied, the strain gauge slightly deforms, producing a millivolt-level analog signal proportional to the applied load. This signal can be amplified and processed using a microcontroller with an HX711 amplifier module.

The sensor is calibrated to ensure linear response with minimal hysteresis, providing stable and precise readings for weights up to 20kg. Its robust alloy steel construction ensures reliable performance even under continuous or repeated loading.

Example Project

A typical application is a smart digital scale. The load cell measures weight, and an Arduino or Raspberry Pi reads the signal via an HX711 amplifier, displaying the accurate weight on an LCD or touchscreen interface.

Another application is a robotic gripper where the load cell detects gripping force for medium-weight objects, ensuring safe handling. It is also suitable for industrial conveyor monitoring, automated packaging, or laboratory force measurement projects.
