DEVICE FOR MEASURING TEMPERATURE DIFFERENCE Russian patent published in 2008 - IPC G01K3/08 G01K7/24 

FIELD: measuring technique.

SUBSTANCE: device comprises two temperature-sensitive resistors connected to the arms of the electric bridge whose measuring diagonal is connected with the input of the amplifier, peak detector connected with the output of the amplifier, store condenser, and pulse generator whose output is connected with the power bridge diagonal and the control input of the peak detector through the delay unit. The storage condenser is connected with the insulated control electrode of one of the temperature-sensitive resistors and output of the device.

EFFECT: enhanced precision.
