ABSTRACT:
An arrangement for registering loads includes an elongated transversely flexible element having two end portions and an intermediate portion therebetween. The end portions are rigidly fastened so as to preclude all lateral movement of the end portions. A compressive force is directed lengthwise of the element and towards the center thereof so that the intermediate portion suddenly flexes laterally when this force exceeds a predetermined limit. Strain gauges are mounted on the elongated element. The strain gauges become stressed when the intermediate portion flexes. The strain gauges generate a signal in response to stressing due to the flexing of the intermediate portion.
