SGA/A & SGA/D Analogue Strain Gauge Amplifier / Signal Conditioner Introduction The SGA offers a wide bandwidth and a wide input signal range. The device can be powered from AC or DC supplies providing excitation for up to 4 x 350 ohm strain gauge bridges. The conditioned output signal can be selected from 0-20 mA, 4-20 mA, 0-10 V, 0-5 V, ±5 V or ±10 V. Options include. Isolated DC supply, DIN rail mount and OEM module. The Strain Gauge Amplifier (SGA) is supplied in a waterproof IP65 NEMA 4 bulkhead mountable case and is robust and fully CE compliant. For a digital version with set point relays, communications and display options please see our Load Cell Amplifier Model (LCA20).
