03 - SGA Half bridge circuit
Wires can be run into the Strain Gauge Amplifier using the three mini cables glands. This allows the lid to be replaced, enabling secure connections to the internal screw terminals without leaving them or the scale and offset adjustment screws exposed.
When using the SGA with a half bridge load cell, two additional resistors must be placed in the circuit. The resistors should be rated to the same value as the maximum resistance of the load cell’s internal resistors and must be placed as shown in the diagram above.
