A Fine-Wire Microtemperature Probe for Atmospheric Measurements
Abstract
Refractive-index fluctuations which affect optical propagation depend mostly on microthermal variations. Fine wire probes are sufficient to measure microtemperature so long as we have ready access to the propagation medium. A complete sensor unit currently in use includes the probe, a Wheatstone bridge and amplifier circuit, and a mechanical support assembly. In providing complete details on how to construct such a unit, we concentrated on a design developed in-house which we know to be effective. The unit is found to have a frequency range better than 0.01 to 100 Hz and responds to minimum temperature fluctuations of 0.015C. Of special importance is the low construction cost of only about $200.
