Load Cell Redesign Improves Accuracy, Performance
IRVINE, Calif.--FUTEK Advanced Sensor Technology's redesign of its LCF400 Tension and Compression Load Cell has improved the output symmetry and accuracy of the sensor, the company said in a recent press release. The new design is a one-piece construction with "structural changes and complete welding," and is available with USB output and metric threads. It uses heat-treated 17-4 Stainless Steel construction for optimal performance.
The LCF400 is offered in the 500- to 5000-pound range and in various outputs (3 mV/V, ±5VDC, ±10VDC, 4-20 mA). According to the manufacturer (www.futek.com), it has advantages of zero-joint failure, low impact due to extraneous loads, and the capability of handling off-center loading more efficiently and effectively.
FUTEK Engineering Manager Richard Walker began the process of redesigning the LCF400 Tension and Compression Load Cell in August of 2006. Using Finite Element Analysis (FEA) software, FUTEK engineers reportedly achieved a design that would improve the accuracy of the model by 20%.
Manufactured in the U.S., the Tension and Compression Load Cell utilizes metal foil strain gauge technology and has nonlinearity of ±0.10%, bridge resistance of 700 Ohms, and deflection of 0.002 to 0.005 inch (nominal). The standard LCF400 Tension and Compression Load Cell can be modified or customized to meet customer requirements.
