For 4 gauge 120–350Ω! Amplifies the bridge voltage by 200 to 1600 times and converts it to a ±5V DC voltage.
The "STA-04G" is an amplification amplifier that connects strain gauges to a voltage logger. It is specifically designed for 4 gauges, amplifying the bridge voltage from 200 to 1600 times and converting it to a ±5V direct current voltage. This is an outdoor specification static strain amplifier powered by DC12V, and when used at a gain of 800 times, it outputs "1μStrain = 1mV," making conversion easy. 【Features】 ■ Gain selectable at 200, 400, 800, or 1600 times ■ Amplifies to 1μStrain = 1mV at 800 times ■ Low power consumption of 15mA (with 350Ω gauge connected) ■ Zero adjustment range of ±2mV (input voltage equivalent) ■ Compact and low-power converter ■ Suitable for civil engineering and construction sites *For more details, please refer to the PDF document or feel free to contact us.
