Futek redesigns tension and compression load cell

A Futek Advanced Sensor Technology product story
Edited by the Engineeringtalk editorial team Nov 19, 2008

Futek Advanced Sensor Technology has unveiled the redesigned LCF400 tension and compression load cell.

The new design features structural changes and complete welding which drastically improves this models output symmetry and accuracy.

In addition to this, the LCF400 is now available with USB output and metric threads.

The model is offered in 500 to 5,000lbs, various outputs (3mV/V, +/-5VDC, +/-10VDC, 4-20 mA), and uses heat-treated 17-4 stainless steel construction for optimal performance.

The modified LCF400 has advantages of zero-joint failure, low impact due to extraneous loads, and has the capability of handling off-centre loading more efficiently and effectively.

Futek engineering manager Richard Walker began the redesign process of the LCF400 Tension and Compression Load Cell in August 2006.

Using Finite Element Analysis software, Futek engineers achieved a design that would improve the models accuracy by 20 per cent.

The first prototype model was first tested in 2007 where minor design modifications, such as USB output, were implemented.

Following the successful testing procedures, the LCF400 tension and compression load cell is now ready for release.

The load cell utilises metal foil strain gauge technology that offers the highest accuracy.

It has nonlinearity of +/-0.10 per cent, bridge resistance of 700 ohms and deflection of 0.002 to 0.005in nominal.

The standard LCF400 tension and compression load cell can be modified or customised to meet a user's requirements and most models are in Futek's inventory making them available for quick delivery.

The model is manufactured in the US.
