Strain gauge measuring amplifiers are used to transfer measured values from force sensors and load cells externally into analogue signals. Measuring amplifiers are therefore used in many areas, such as in hydraulic presses, rolling machines, bending machines and strength testing machines. The motrona DM222 (2-channel) measuring amplifier transfers the strain gauge signals, which can then be processed by end devices with an analogue input. The special feature is the equipment of the measuring amplifier with two strain gauge inputs and two analogue outputs. The measured values of the inputs can be linked with one another or also operated independently. Our strain gauge measuring amplifier is also available as a 1-channel version DM221. In addition to the measuring amplifiers, a strain gauge indicator from our touchMATRIX® series is also available.
