1.This is a half-bridge load sensor, widely in hopper scales, platform scales, platform balance, belt scales and other electronic weighing devices.
2.When the half-bridge is being stretched, it sends signal via the red signal wire.
3.You can use multiple load sensors simultaneously to increase the capacity range. Such as two sensors full-bridge measurements: 50kgx2=100kg; four sensor full-bridge measurements: 50kgx4=200kg Parallel use to add additional capacity.
4. Wires connected: white wires are connected in series, black wires are connected in series, and red wires for power supply and output.
