The compact analog charge amplifier PACEline CMA converts signals from all piezoelectric sensors into a +/- 10V standard signal. Due to this, it can be used for many measurement tasks involved in production, e.g. joining processes, press applications, or assembly monitoring.

Simple and secure handling, absolute reliability and a good price-performance ratio are the outstanding features of this product. Integrated into the piezoelectric force measuring chain “HBM PACEline“, the analogue charge amplifier CMA enables reliable measurement results in very short set-up times.

• Accuracy class: 0.5
• A measuring range of 1000 .. 5.000.000pC (pico-Coulomb) is available, depending on the version being used
• Two calibrated measuring ranges 100% and 20%
• The signal inputs and outputs are galvanically insulated.

• Fixed measuring ranges depending on the model –  from 1000 to 5,000,000 pC
• 2 calibrated measuring ranges per model 100% and 20%
• Accuracy is always guaranteed, even with small partial load ranges (accuracy class 1%)
