Miniature Load Cells

For over two decades, FUTEK has been a leader in sensor miniaturization, researching and developing high-performing micro-miniature sensor load cells (aka mini load cell) that push the boundaries of measurement technology. These models measure both tension and compression, have a collective capacity range from 10 grams to 20000 pounds of force, and are ideal for applications that require high precision and endurance. FUTEK also offers submersible option for this series.

Nano Sensors (< 10mm)	QLA414	QLA424	QLA427
The Nano load cell series includes micro-miniature sensors with unprecedented capabilities. Mounting provisions in this series include load button, through-hole, and monolithic crip, an industry breakthrough for a sensor this small. In addition, the Nano sensors' multi element, side load compensated 1000 Ohm full-bridge instrumentation is encased with laser-welded construction with patent-pending non-active interconnect packaging providing environmental protection. The Nano sensors (aka subminiature load cells), open up a world of possibilities for industries such as advanced automation, semiconductor, electronics assembly, and robotic tactile sensing.
