Abstract
A review of the literature pertinent to globe thermometers reveals that there is some disagreement as to the exact time and manner of response of the instrument to changing thermal conditions. The paper presents several theories of globe thermometer response and examines the transient thermal responses of various configurations of 10 cm and 15 cm diameter globe thermometers in relation to basic parameters of heat transfer. An electrical analogue of the globe thermometer is discussed from which suggestions for the improvement of its response are obtained. These include the use of a gas of low thermal capacity and high thermal conductivity in the globe, reduction of the thickness of the globe material and the use of small central temperature sensors of low thermal capacity.
