PORTABLE MODULAR SCALE SYSTEM
First Claim
1. A modular scale system comprising:
- at least three load sensors for being removably positionable under a platform, each of the least three load sensors housing a load cell and having an extension foot in physical communication with the load cell for relaying a force to the load cell, the load cell providing weight data in response to the force;
a display unit releasably coupled to at least one of the at least three load sensors for displaying text corresponding to the weight data provided by each of the at least three load sensors; and
,winder cables for releasably coupling each of the at least three load sensors to the display unit.

Abstract
A modular scale in the form of a kit or a system includes a plurality of load sensors, a display unit, and a plurality of electrical communication links for electrically connecting the load sensors to the display unit. The load sensors include connectors, such as jacks, for releasably receiving a complementary plug of a cable. The other end of the cable includes another plug for releasable insertion into a complementary jack of the display unit. One of the load sensors can be a master load sensor for receiving weight data of the other load sensors, referred to as slave load sensors. The master load sensor sums the weight data provided by itself and the slave load sensors, for providing combined weight result data. The scale also includes a rigid case for carrying the various modules of the scale, the case being adapted for use as a weighing platform when opened and supported by the load sensors over a surface.
