This design provides an elegant solution to elevator load weighing applications. The purpose of this control is to provide meaningful feedback pertaining to the load that is in the elevator cab. This system can accept any one of four different types of sensor for determining cab displacement. A linear potentiometer, LVDT, proximity sensor on a strain gauge may be used with this system. Load feedback is provided by these different mechanisms. Relays are provided and may be programmed, for example, to turn ON and OFF at user defined loads.
