Page 3: Introduction
Each channel is DC isolated, with an output range of ±9V and a signal gain adjustable between approximately 25 and 1000. Connection to the SGA01 is made via screw terminals, with mini cable glands to allow wires to be run out of the unit when the lid is in place, preventing interference with the screw terminals and the scale and setting adjusters. -
Page 4: Half Bridge Circuit
SGA01 Strain Gauge Amplifier Half Bridge Circuit 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. -
Page 5: Calibration
SGA01 Strain Gauge Amplifier Calibration Calibration of the Strain Gauge Amplifier takes place in two steps, or two steps per channel if more than one channel is being used: offset calibration and scale calibration. First calibrate the offset by subjecting the load cell to the conditions that relate to a zero value (typically no load). With the required load applied, adjust the “Offset”... -
