Abstract (en)

[origin: EP0730972A2] The power electronic system for the pressure control unit (14) regulates the amplitude of the pressure head voltage corresponding to the ambient temperature. The power electronic system is combined with a control unit (6) which operates with pre-heating and pressure impulses. A voltage distributor (R8,R9) incorporates the temperature sensor (R9) in the form of a thermistor for measuring the ambient temperature.
