Abstract
An electronic weighing scale that includes an inner housing and an outer housing surrounding the inner housing. In one embodiment, the inner and outer housings are not secured to one another and are spaced apart by shock-absorbing spacers designed to absorb shock of impact loads such as may be caused by the scale being dropped. The inner housing includes a chassis defining a load cell cavity that contains a load cell. The inner housing also includes an electronics compartment closure that together with the chassis define an electronics compartment that contains electronics of the scale, including display electronics and user-controls electronics. In one embodiment, the electronics compartment is hermetically sealed to protect the electronics from moisture.
