DM221/DM222: Strain Gauge Amplifier >>> Analog
DM221: one strain gauge input and one analog output
DM222: two strain gauge inputs and two analog outputs
Strain gauge measuring amplifiers are used to transfer measured values from force sensors and load cells externally into analog signals. Measuring amplifiers are therefore used in many areas, such as in hydraulic presses, rolling machines, bending machines and strength testing machines. In addition to the measuring amplifiers, a strain gauge indicator from our touchMATRIX® series is also available.
