Used widely in hopper scales, platform scales, platform balance, belt scales and other electronic weighing devices This is a half-bridge load sensor, which is widely used in weight scales. When the half-bridge is being stretched, it sends signal via the red signal wire. You can use multiple load sensors simultaneously to increase the capacity range. Two sensors full-bridge measurements: 5kgx2=10kg Four sensor full-bridge measurements: 5kgx4=20kg Parallel use to add additional capacity. Notice: The Pressure head is not included.
