An Evaluation of Radiation Compensating Thermocouple Temperature Sensors

摘要

A copper constantan thermocouple temperature sensor designed to automatically compensate for the effect of radiation sources or sinks in the field of view of the sensor is evaluated as a meteorological air temperature sensor. Performance is compared with a conventional thermocouple sensor during various exposures, both shielded and unshielded from solar radiation and clear night sky. Findings indicate the compensated sensor is superior to a shielded conventional sensor. (Author)
