Distortion Gauge Amplifier "STA-04G"

Distortion Gauge Amplifier "STA-04G"

For 4-gauge 120 to 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 a strain gauge to a voltage logger. It is dedicated to 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 an amplification factor of 800 times, it outputs "1μStrain = 1mV," making conversion easy. 【Features】 ■ Amplification factors selectable: 200, 400, 800, 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.

Distortion Amplifier "STA-12G"

Distortion Amplifier "STA-12G"

The successor to "LCA-124"! The 1 gauge is dedicated to 120Ω, but the 2 gauge can be used for 100 to 1000Ω.

The "STA-12G" is an improved version of the old 120Ω gauge amplifier "LCA-124 (discontinued)," designed for 1 and 2 gauge applications. It has changed the amplification ratios from 1,000 and 2,000 times to 800 and 1,600 times. With this change, for example, when set to 800 times, a strain of 1μStrain is output as exactly 1mV, making conversion easier. Although the reduction in amplification ratio has decreased amplification accuracy, it has become an overall user-friendly, low-power strain amplifier. 【Features】 ■ Amplification ratios selectable: 200, 400, 800, 1600 times ■ Amplifies 1μStrain to 1mV at 800 times ■ Low power consumption of 25mA (when connected to a 120Ω gauge) ■ Zero adjustment range of ±2mV (equivalent input voltage) ■ Compact strain amplifier with low power consumption *For more details, please refer to the PDF document or feel free to contact us.

Distortion Amplifier "STA-12L"

Distortion Amplifier "STA-12L"

For measuring the strain of steel materials and concrete at civil engineering sites! Measurable with commercially available 0-5V loggers.

The "STA-12L" is a distortion amplifier that simplifies the functions of the standard 120Ω gauge amplifier "STA-12G" and offers it at a lower cost. It has a fixed amplification rate of 1μ strain = 0.5mV, with zero distortion and a 2.5V output. It converts changes in strain from -4000 to 5000 microstrains into a voltage range of 0.5V to 5V. Additionally, while the amplification rate is lower and there is no zero-point adjustment, the output voltage remains within the 0 to 5V range, allowing for measurement with commercially available 0 to 5V loggers. 【Features】 ■ Accuracy and stability are comparable to the higher-end STA-12G, making it suitable for practical measurement tasks. ■ The terminals are soldered, reducing contact resistance errors from lead wires. ■ The gain is fixed at 400 times, amplifying 1μ strain to 0.5mV. ■ Outputs -4000μ = 0.5V, 0μ = 2.5V, 5000μ = 5V (max 9000μ = 7V). ■ Operates on a 9 to 15V power supply with a current consumption of 25mA, making it energy-efficient. *For more details, please refer to the PDF document or feel free to contact us.
