DEVICE TO DETERMINE CHARACTERISTICS OF MATERIALS Russian patent published in 2010 - IPC G01N25/18 

FIELD: test equipment.

SUBSTANCE: invention relates to thermal control over materials. Proposed device comprises additionally three thermocouples, three amplifiers, four comparators, two storage units, two integrators, three subtraction units, two adders, two scalers and division units. Note here that outputs of 2^nd, 3^rd and 4^th thermocouple are connected via 2^nd, 3^rd and 4^th amplifiers with first inputs of 2^nd, 3^rd and 4^th comparators, respectively. Output of 2^nd comparator is connected with first control input of 6^th integrator with its second control input connected to output of 3^rd comparator. Third control input of 6^th integrator is connected to first control input of 7^th integrator, starting terminal, control input of 3^rd storage unit and first control input of 4^th storage unit. Data input of 6^th integrator is connected with reference voltage source output and data input of 7^th integrator.

EFFECT: expanded operating performances.
