Thermoelectric Bimetal Thermometer

Temperature Insensitive Curved Bimetal Elements

Space structures are subjected to appreciable temperature variations when they enter and leave direct solar radiation zones. These variations cause thermal strains and related structural distortions. Such deformations are often a nuisance and much engineering e ort, such as active control methods, is currently being invested in reducing the deformations and alleviating their e ects.

An Imaging Radiation Thermometer

For many years radiation thermometers have been used to make non-contact temperature measurements of hot objects, particularly in industrial situations such as reformer furnaces, steel reheat furnaces, and ceramics kilns. They occupy an important niche in temperature measurement since any other type of thermometer would have very slim chances of surviving in these and other such hostile environ...

An improved tele-thermometer.

A thermistor leaf thermometer.

An instrument is described which allows measurements of leaf temperature within about 0.3 C. It consists of a special thermistor probe, a small circuit box, and a standard ammeter. The circuit box can easily be fixed to the meter and contains a battery, which passes 0.3 milliampere through the thermistor, and also contains an integrated circuit amplifier, so that the meter reads 20 C full scale...
