Page 5: Introduction
1.0 INTRODUCTION • The CBC series provides accurate, fast and versatile counting scales. • There are 2 type of scales within the CBC series- CBC scales are gram / kilogram only scales and the CBCa scales are changeable from pounds to kilograms. The scales have the same functions except that CBCa scales have the ability to toggle between the two weighing units. -

Page 10: Cbc Description
4 strain gage sensors mounted in a particular way on the metal structure. These 4 strain gauges are connected in such a way that they form a wheatstone bridge. See figure below. In the simplest load cells there are only the 4 resistances of the strain © Adam Equipment Company 2007... - Page 11 Most load cells used in scales are not as simple as this example. They have additional resistance elements added to compensate for temperature variations and to set the outputs to correct voltages. The circuit of a typical load cell is shown below- © Adam Equipment Company 2007...
- Page 12 If the load cell has been damaged the no load voltage will likely be greater than 3mv or the loaded voltage will be grossly different from the expected value. Remember the loaded voltage will be offset by the amount of zero load voltage measured. © Adam Equipment Company 2007...
