Aim Strain Gauge Amplifier

Technologies 24-Bit ADC-to-CAN Amplifier is designed to measure the voltage signal from a strain gauge or load cell with class-leading precision & ultra-low noise, and outputs the raw voltage, temperature, and user-calibrated output with advanced temperature compensation via CAN. The amplifier measure’s differential voltages with a resolution of 1μV and RMS noise of only ±750nV at a sampling frequency of 100Hz. The differential voltage and temperature is broadcasted via CAN but it may also be programmed to simultaneously transmit a calibrated output (convert voltage to strain/force) with linear or advanced tabular temperature compensation.
