Description

of the strain-gauge amplifier ZET 052

Measuring strain-gauge amplifier ZET 052 is represented by 2-channel DC amplifier with differential output, adjustable amplification ratio, and power supply voltage. This instrument is intended for connection of the strain-gauge transducers, amplification, and transmission of the analog output signals to the measurement unit. The principal task of the strain-gauge amplifier is to increase the output signal level from several mV up to several V. In this particular example, we use balancing, i.e. compensation of the initial offset of bridge or transducer within the limited range. In addition to that, there is also used calibration (also referred to as “gauging”), i.e the known offset value allows to evaluate sensitivity level of the measuring circuit.

Amplifier ZET 052 can also be used for static and dynamic measurements of loads, deformations, torque, temperature, and other physical values.

Simple controls and compact dimensions allow to integrate this module into various multi-channel data acquisition systems, while the analog output can be connected to the FFT Spectrum analyzer or ADC module.
