Product outline
A general-purpose DC amplifier with expanded basic functions. With built-in bridge power supply voltage for strain gauge type sensors, this is ideal for the measurement of pressure, load, torque and displacement. Because AM20AZ equipped with current output and electronic auto zero function in addition to standard voltage output is also included in our product lineup, it extends the range of applications.
