Straight Bar Load Cell 20Kg

The Straight Bar Load Cell 20Kg is a premium strain gauge-based load sensor engineered to measure forces up to 20 kg with high accuracy and stability. Its straight bar design ensures minimal deformation, precise linear response, and consistent measurement across multiple load cycles. This makes it an ideal choice for industrial weighing, precision electronic scales, laboratory testing, robotics, and smart IoT projects.

Equipped with a strain gauge technology, the sensor converts mechanical load into a measurable electrical signal, which can be amplified using modules like HX711 and easily interfaced with microcontrollers such as Arduino (https://electroway.org/product-category/arduino-and-accessories/arduino-boards/) or NodeMcu (https://electroway.org/product-category/iot-and-smart-solutions/iot-modules/nodemcu/) for digital readouts. Its robust alloy steel or stainless-steel construction ensures long-term reliability, even under frequent use.
