HEAT FLUX SENSOR Russian patent published in 2005 - IPC

FIELD: measurement technology; heat supply systems for metering heat fluxes of liquid or gas.

SUBSTANCE: proposed sensor designed for measuring heat flux of energy carries having various compositions and temperatures has signal coil as well as thermal element, first support of turbine shaft, turbine, reset spring, and second support of turbine shaft, all mounted in tandem on turbine shaft. Thermal element is made in the form of case filled with working medium and accommodating bellows. One end of turbine shaft is inserted in thermal-element bellows. Turbine is made in the form of bladed wheel whose rim carries permanent-magnet inserts and is mounted in sleeve bearing. Power coil is disposed so that magnetic field of permanent-magnet insert crosses its circuit.

EFFECT: enhanced reliability and measurement accuracy, enlarged functional capabilities.
