An Adiabatic Calorimeter for Contact Calibration of Heat Flux Sensors,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
The characteristics of calibrating heat flux sensors by radiation and contact methods are examined. Described are the design and theory of a quick-response adiabatic calorimeter with automatic compensation for heat losses, developed in the Institute of Technical Heat Physics of the AS USSR. As the zero-indicator, monitoring the presence of heat leaks in the calorimeter, a high-discrimination thermoelectric battery with a given number of microelements is used, which prevents heat losses of the calorimeter from exceeding 0.1-0.2 percent. The calorimeter was designed for contact calibration of heat flux sensors. Author
