The German Voith electro-hydraulic converter DSG-B07212 can efficiently convert the 4-20mA signal of the electronic governor into a hydraulic signal to provide precise control for the power cylinder. The following is a brief introduction to the main features of the Voith DSG series of electro-hydraulic converters.
The magnetic drive of the Voith electro-hydraulic converter DSG-B07212 works together with the pressure reducing valve in the hydraulic section to give it the function of a pressure regulating valve. Its dynamic and hysteresis-free conversion results are better than 0.1% accurate and are not affected by air gaps, hysteresis, temperature or voltage fluctuations.
It is recommended to use a filter oil that meets NAS1638 class 7 or IS04408 class 16/13. The short time (t<35 ms) from the change of the mA input signal to the proportional stable pressure ensures that the electronic and mechanical parts are fully functional even in harsh environments.
All electronics of the Voith electro-hydraulic converter are contained in the vessel and are designed to ensure higher input pressures, ranging from 0~3000psi.
