Hydraulic control engineering CommonTec electronics was in its origins hydraulic control engineering. Over 20-year of experience in hydraulic control engineering like servo hydraulic or proportional hydraulic ensures practicable solutions. From the initially extensive and expansive 19 " - racks became ever more compact electronic units. Some years ago CommonTec developes solutions with a mix of digital signal processing and analog circuits. Both ways, the digital as well as analog signal processing owns their advantages and disadvantages. CommonTec combines, where it is possible, to offer to the customer the optimum at dynamics and accuracy. This guarantees cost-conscious systems with a high sensibility and dynamic.
