For two types of load cell which includes a load-receiving member coupled to a support member by three or two parallel beams, temperature and strain distribution caused by step increase of surface temperature were calculated by using the finite element method. For the initial short duration about several seconds, load-sensing beams were deformed by the temperature gradient within the load-receiving member that had been exposed to a step increase of temperature. Beyond this short time, the beam deformation was caused by the temperature difference between the support member and the load-receiving member. Based on the observation of the transient behavior of beam deformation, the nature of zero-shift induced by transient temperature could be clarified. The mechanism of beam deformations suggested be the calculations was confirmed by a experiment using radiant-heat flux.
