Core liquid position detector is piled to nuclear power station reactor

The utility model provides a core liquid position detector is piled to nuclear power station reactor which characterized in that: including the pressure -bearing sleeve pipe, armor heating cable, armoured thermocouple, nickel powder and al2O3 powder, contain armoured thermocouple in the pressure -bearing sleeve pipe, N (N >= 2 a) armoured thermocouple who is heated and the armor heating cable that includes N (N >= 2) section heating resistor silk, armoured thermocouple is located pressure -bearing sheathed tube bottom, fill the compacting nickel powder in the regional intussuseption of N section heating resistor silk axial length, in addition's axial is regional, fill compacting al2O3 powder, armoured thermocouple is right with the thermocouple measurement that the liquid level was measured to the armoured thermocouple constitution of heating department. Its sensitivity that had both increased liquid level measurement has improved the measuring interference killing feature again. 种核电站反应堆堆芯液位探测器,其特征在于:包括承压套管、铠
