摘要：The inventive device comprises a voltage divider (Rv1, Rv2) to whose twoterminals the oscillator signal with a phase position (area 2) that is mutually opposed issupplied until, in the instance of a switched-on probe heating, the voltage (VRpvs) that isproportional to the probe internal resistance (Rpvs) falls below a predetermined setvalue (set), whereby, at this point in time, the output signal of the oscillator (OSZ) issupplied to both terminals of the voltage divider (Rv1, Rv2) with the same phase position(area 1) thus effecting an amplitude change-over (amplitude amplification).
