| 摘要 | A temperature-sensitive unit operative for generating an analog temperature-indicating electrical signal is placed in the veryhigh-temperature environment and generates a signal indicative of the temperature to which it is exposed. Also placed in the veryhigh-temperature environment is a heat-insulating container containing an electrical-energy-consuming electronic buffer storage circuit generating heat during operation and protected by the container from the heat of the very-high-temperature environment. The electronic buffer storage circuit is electrically connected to the temperature-responsive unit and is operative for receiving the analog temperature-indicating signal and temporarily storing a corresponding signal indicative of the value of the analog temperature-indicating signal. Subsequently, the electronic buffer storage circuit is brought into a cooler environment and is there connected to an electrical-energyconsuming readout device, such as a digital display device which generates heat during operation, and the stored signal is read out. This results in a slower build-up of temperature in the heat-insulating container than if the read-out device were incorporated therein. The electronic buffer storage circuit can include an analog-to-digital converter circuit, and preferably is a very small electronic circuit having a very low heat generation rate, to minimize the rate of temperature build-up in the heatinsulating container. | ||||||
