Description
The Michigan Scientific SGA3A Strain Gage Amplifier Box is ideal for use with any of MSC’s wide
variety of three directional load cells. The SGA3A provides highly accurate excitation voltage to the
load cell, a stable differential amplifier, and a remotely activated shunt resistor for system span
verification. The result is an accurate high level voltage output signal. The shunt calibration can be
easily invoked with the flip of a switch when used with a Michigan Scientific PS-DC or PS-AC power
supply.
MSC will select the appropriate amplifier gain and shunt resistors for use with your selected load cell. The fixed precision resistors are factory installed.
The standard SGA3A is comprised of three independent miniature strain gage amplifiers. MSC can customize the amplifier box to any number of channels desired. The SGA3A can also incorporate strain gage summation wiring. This saves cost when using an array of load cells to measure three directions of force because only one amplifier box is required.
