04 - SGA Quarter bridge circuit

Table of contents
No headers

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 in conjunction with a quarter-bridge load cell, three additional resistors must be placed in the circuit. These resistors should be rated to the same value as the maximum resistance of the load cell’s internal resistors and must be placed according to the diagram above.
