The SGA range of strain gauge amplifiers offers great flexibility. Both the 110/230Vac powered SGA/A and 18-24Vdc powered SGA/D offer 10volt on-board excitation, capable of powering up to four 350ohm strain gauge bridges. Please note that the 110/230Vac version can also be DC powered.
With an input sensitivity range of ±0.06 to ±29 mV/V. Any sensor in this input range can be amplified to give ±10V, ±5V, 0-10V, 0-5V, 0-20mA or 4-20mA outputs.
There is also a wide offset control, using a combination of switches and a potentiometer. This gives an adjustment range of ±70%.
The SGA is an ideal product for many OEM customers, as its flexibility means that it can be configured to suit most applications.
The SGA can be supplied calibrated with any of LCM Systems sensor range or could be integrated within a larger instrumentation system.
