Claims
- 1. A nuclear hardened controller apparatus for automatically adjusting the pump speed according to the temperature of oil to be pumped comprising:
- means to generate a voltage differential based on the temperature of the oil in a reservoir;
- means to adjust the load to the motor correlated to the viscosity of oil in a reservoir, said means to adjust comprising a network of parallel thermal switches;
- means to connect said means for generating voltage differential with those of said means which adjust the load to the motor.
