The SGA has adjustable excitation voltage and a high accuracy amplifier to provide a high level DC voltage output. An offset adjustment potentiometer is easily accessible on the front panel. The output is ideal for direct connection to data acquisition boards or test controllers which require high level voltage or current inputs. All models are supplied with a universal power supply and adapters for your country: specify regional adapters when ordering. A 2.5 m (8 ft) output cable is included to connect to external systems. Calibration with an extensometer (for each channel) is included.
