Analog Converter for connecting Load Cells
SGA
The SGA Converter is an analog signal conditioner specific for load cells and for transducers based on strain gauges Wheatstone bridges
SGA converts the load cell output signal to different kinds of analog standard outputs used in industrial instrumentation. With DIL switches can be selected: Current output 0-20 mA or 4-20 mA; “Unipolar” voltage output 0-5V or 0-10V and “Bipolar” voltage output ±5V o ±10V
It has integrated filter with selectable cut-off frequencies from 1Hz to 5 KHz, for reducing oscillations induced by mechanical vibrations and/or electrical noise, providing stable readings under adverse conditions
