Total Dissolved Gas sensor for Fluidic Systems

TauTheta Instruments (www.tautheta.com) proposes to develop and commercialize a Total Dissolved Gas sensor for fluidic systems used in industrial, military, aerospace and petrochemical applications. The proposed sensor uses an innovative combination of materials and operating principles that enable it to withstand high temperatures, harsh chemical and abrasive mechanical environments. The primary objective of the Phase II will be the development of a Total Dissolved Gas (TDG) sensor for use in hydraulic fluid using the patent-pending sensing technology developed in Phase I. The multi-purpose sensor developed in Phase II will function as a stand-alone dip probe, or be incorporated into a purifier or multi-sensor suite using standard fittings. The output of the sensor will be readable by computer or handheld device, and will also be compatible with the sensor suite under development by WPAFB. The technology will be designed for compatibility with fluids 2006-552-MIL-PRF-5606, 2006-379-MIL-PRF-87257 and 2006-505 MIL-PRF-83282. The target specifications are a 10% accuracy in TDG reading over 1% to 18% TDG, at up to 100psi, and over the temperature range -40C to 135C.
