Analog signal conditioner SGA series

multi-channelamplifiersingle-channel

The SGA series signal conditioners are ideal for cyclic and high speed testing where no display is needed. Available in single and dual channel versions, they provide the signal conditioning electronics needed for a strain gage based extensometer. 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. Specifications • Zero Adjustment Knob(s): On front panel.
