ZERO HEAT FLOW TEMPERATURE MEASUREMENT SENSOR Russian patent published in 2014 - IPC G01K1/16 G01K13/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to thermometry and can be used for measurement of inside temperature of an object body. Zero heat flow temperature measurement sensor (100) includes layer (107), sensor (105) of the first temperature gradient, modulator (103) of the first heat flow and controller (102) of the heat flow modulator. Layer (107) has the first side (112) and the second side (108), which are located opposite each other. When being used, the first side (112) is the closest one to object (113). Layer (107) is intended to obtain the first temperature difference above layer (107) in response to the first heat flow in the first direction from the first side (112) to the second side (108). Sensor (105) of the first temperature gradient reads off the second temperature difference in the second direction on the first side (112) of layer (107). The second direction comes from the first boundary of the first side (112) in the direction to the second boundary of the first side (112). Modulator (103) of the first heat flow is arranged on the first side (112) of layer (107) and is designed so that it can change the second heat flow in the second direction on the first side (112) of layer (107) to have an effect on the second temperature difference. Controller (102) of the heat flow modulator controls modulator (103) of the first heat flow based on the read-out second temperature difference to reduce absolute value of the second temperature difference.

EFFECT: improving accuracy of determination of inside temperature of an object body.
