A 7075-T6 aluminum alloy has been used for the elastic column, in which 8 uniaxial, 120-Ω strain gauges have been bonded and connected to form a full Wheatstone bridge to detect the strain. The chosen geometry makes the transducer insensitive to moments and, also, to the temperature. Experimental tests using a universal testing machine to imposed compression force to the load cell have demonstrated that its behavior is linear, with sensitivity of 2.90 μV/kgf ± 0.34%, and negligible hysteresis. The designed force transducer response to a dynamic test has been comparable to that of a commercial load cell. © 2005 IEEE.1767-1772engForce measurementForce transducerLoad cellsLoad measurementRocketsStrain gaugeThrust measurementForce transducersUniversal testing machineAluminum alloysHysteresisMilitary rocketsPropellantsStrain gagesStructural loadsTrabalho apresentado em evento10.1109/IMTC.2005.1604475Acesso aberto2-s2.0-33847138063
