Fatigue-Rated Load Cells

The rated output of a load cell is the signal produced at full-scale capacity under specified excitation, typically expressed as a percentage of full scale or in mV/V. SensorData Technologies' fatigue-rated load cells are precision strain gage-based sensors designed to deliver highly accurate outputs, with nonlinearity and hysteresis as low as 0.07% on models like the F341–F347 series and 0.15% on the F502 series, ensuring repeatable and precise force measurement across their full rated capacity ranges.

A fatigue-rated load cell is specifically designed and tested to withstand millions of repeated load cycles without structural failure. SensorData's fatigue-rated load cells use a shear web design and are guaranteed against fatigue failure for 100 million fully reversed load cycles, making them suitable for dynamic testing, durability testing, and cyclic force measurement applications.

SensorData's fatigue-rated load cells cover a wide range of capacities. The F312 series handles 200 to 3,000 lbs, the F200 and F341–F347 series reach up to 50,000 to 500,000 lbs, and the F502 series spans 5K to 100K lbs. The F654 series covers 5K to 25K lbs, allowing selection for light to very heavy-duty applications.

SensorData Technologies' fatigue-rated load cells serve a broad range of industries. They are used in material and structural testing machines for repeatable force measurement over millions of cycles, in aerospace and defense airframe test fixtures, in automotive manufacturing for hydraulic actuator force measurement and press calibration, and in industrial weighing and civil engineering applications such as tank, silo, and hopper level control, as well as rolling mill force monitoring.

Yes. Many SensorData fatigue-rated load cells support both compression and tension measurements. The F654 series, for example, features male and female thread configurations (1-14 UNF-2A and 1-14 UNF-2B), enabling tension and compression mounting. Optional tension plates and spherical load buttons are also available to adapt sensors for various loading orientations.

SensorData Technologies' fatigue-rated load cells are constructed from SAE 4340 alloy steel, a high-strength material known for excellent fatigue resistance and toughness. All units feature a satin nickel finish that enhances corrosion resistance and durability, ensuring long service life in demanding industrial and laboratory environments.

SensorData Technologies offers in-house calibration with customer-supplied electronics, technical consultation for custom designs and capacities, and mating connectors supplied with each product. Interconnecting cable assemblies are available as options. The company also provides a 100% satisfaction guarantee and free calibration on certain models for the first four years after purchase. With over 25 years of experience since 1993, their team supports automotive, aerospace, military, and material testing clients worldwide.
