High-precision pressure amplifier circuit is mainly used in small amplification system. The AD624 is a precision low-noise instrumentation amplifier which can be used in a small sensor output signal amplification system. The figure shows the high-precision pressure amplifier circuit composed of the AD624. The sensor is a standard strain gauge bridge sensors. The bridge voltage uses+ 9.00V, potentiometers R8 and R6 to zero, in which R6 is coarse, R8 is fine. The amplifier output can be directly related to high-precision A / D converter connected.
