PYROELECTRIC TRANSDUCERS FOR HEAT-TRANSFER MEASUREMENTS
Thomas A. Perls, J. J. Hartog · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1961
The state of the art for heat-transfer measurements is briefly reviewed. It is shown that heat-transfer rate may be measured with extremely short response times by the use of a variety of temperature-sensing devices followed by a simple electrical differentiator. Theoretical considerations are presented for pyroelectric ceramic transducers, and it is shown that these sensors constitute a particularly simple type of temperature-measuring device with differentiation. Evaluation and calibration procedures, applications, advantages, limitations, as well as typical circuitry and installations are discussed. (auth)
