Abstract
The effectiveness of a 2 inch diameter black globe thermometer was evaluated. Stabilized temperatures and response time for 2, 4, and 6 inch diameter globes were determined by placing the globe in a radiant field and air stream. Results were compared with thermocouple configurations and a mercury in glass thermometer. The glass thermometer required a long stabilization time. Thermocouples gave the fastest response. Response time was not significantly improved using the 2 inch globe. The 2 inch globe had an error of 9 degrees F. The authors conclude that the errors from the 2 inch globe thermometer are excessive. They suggest that a satisfactory response time can be achieved using a 6 inch globe with a small gauge thermocouple.
