DEVICE FOR MEASUREMENT OF MIRROR ABSORPTION FACTOR Russian patent published in 1997 - IPC

FIELD: metering equipment. SUBSTANCE: the device uses a radiation source optically integrated with an absorbing cone through a mirror, mirror and cone cooling system with coolant inlet and outlet manifolds, temperature-sensitive elements. In addition the mirror and absorbing cone are furnished with branch-pipes accommodating the temperature-sensitive elements made in the form of a multiple- junction thermocouple and oriented in the direction opposite the motion of coolant. The coolant inlet and outlet manifolds of the absorbing cone are arranged on its back surface, and the cone cooling ducts are made on its lateral and back surfaces. The branch-pipes are connected to the coolant inlet and outlet manifolds of the absorbing cone and mirror. EFFECT: enhanced accuracy. 2 cl, 2 dwg
