Seat belt Load Cell

Measurement of the tensile forces in the belt during crash

The seat belt will follow two fully separable shafts of the measuring body.
The shafts can be unlocked by pushing a button. The shafts can rotate in the locked state.
The induced force causes an elongation of the measuring point of the body. Elongation is measured by using strain gauges. The strain gauges are connected into a Wheatstone bridge circuit in order to eliminate the temperature effect on zero.
The use of light titanium minimizes the influence of the measuring system by the low weight of the transducer.
The non-linearity, that is dependent on the system, can be compensated by an integrable optional linearization circuit part.
The standard model without linearization is delivered with a calibration in accordance with SAE (Polynomial 3. Grades).

Up to 11 consecutive events can be captured at a rate of 250ms per event. 2s of video can be stored when operating at 1,000FPS.
