Abstract
The present device is a light transmission probe which is designed to transmit light through a fluid, which is held by a tank or in a pipe or the like. By analyzing the change in amplitude and/or frequency of the light transmitted, certain parameters of the fluid can be determined. The present light transmission probe, in a preferred embodiment, includes a sapphire rod or window as the light conducting medium. Further, in a preferred embodiment, the sapphire rod has a layer of titanium molymanganese metallized to its lengthwise surface and the metallized larger is fused to the inside cylindrical aperture of a stainless steel housing. The combination just described provides a probe which does not react to the presence of chemicals normally used in the chemical industry and can withstand relatively high pressures and relatively high temperatures.
