DEVICE FOR MEASURING TEMPERATURES DIFFERENCE Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: device has two thermo-resistors, amplifier, indicator or registration device, voltage splitter. Also, device has serially linked selected peak detector, recording capacity, controlled frequency generator, pulse delay cascade, strobe pulse generator. Strobe pulse generator is connected to control input of detector. Output of controlled frequency generator is additionally connected to diagonal of bridge power and to input of indicator or registration device. Input of peak detector is connected to output of voltage splitter.

EFFECT: higher sensitivity and precision of measurements.
