Loadstar Sensors RSP1 resistive load cells are built using strain gauges and offer excellent accuracies, good off-center tolerance and temperature compensation.  Most common scales use these type of load cells. They are available in 5 kg, 10 kg, 20 kg and 50 kg capacities and accurate to 0.03% of full scale. This kit includes a RSP1 load cell, an AI-1000 Analog load cell interface with 0-5V DC output.
