System and method for microstrain measurement

摘要: A microstrain sensor is provided for measuring deformation, and indirectly, other parameters such as acceleration, temperature, pressure, force. Rather than providing several discreet resistance paths, the utilizes input output conductors connected to a single piece of film through which current travels indicate resistance. The provides superior external effects, temperature gradients, that decrease accuracy sensor's readings. Such sensors may be easily adapted use in situations opposing stresses are present, dually constrained members, by disposing separate or unitary sections on opposite sides zero stress point, central plane fixed-guided beam. utilized many different applications, including automotive safety systems. system utilize measure weight-in-seat, frame seat belt tension, order properly control elements vehicle belts airbag installed buckle lath/unlatch characteristic belt, well tension belt.
