Performance in Magnetic Fields |
Figure 2 shows the remarkable performance of the RO-600 in high magnetic fields. With a temperature error of less than +-1.6%, a simple linear formula allows correction of any apparent temperature, measured in a field up to 16 Tesla, to the actual temperature. This result may extend to higher fields, and is useful for a broad temperature range down to 36mK. It is independent of the orientation of the sensor in the magnetic field. Since errors in temperature of uncalibrated thermometers, in any magnetic field up to 16 Tesla, accumulate to only a few percent, the RO-600 is exceedingly useful in most low temperature applications, and is versatile enough to use in most low temperature environments.
|
Interchangeability |
Besides being remarkable repetitive on successive cooldowns, RO-600 series exhibit uniform response within groups. Figure 3 shows a typical R vs T curve for Grouping Sensors. Resistance variation at a given temperature is less than 1% for temperatures above 70mK.
|
Sensitivity |
Figure 4 represents the sensitivity of a typical RO-600. This sensitivity is a smooth and monotonic increase at lower temperatures.
