Environmental Insturments, Inc. (EII) Proposes to conduct advanced engineering development of its model 200m solid state (no moving parts) wind velocity and wind direction measurement system with the objective of adapting the system for operation in a naval environment. This advanced engineering development will include modification neccessary to pass electro-magnetic interference tests, interrogation relating to the possible effects of salt air on performance, feasibility of different non-corrosive probe envelopes, and compliation of concrete evidence that EII's solid state wind measurements systems peforms in severe naval environments including high winds, tropical storms, driving rain, freezing rain, and snow storms. EII's state-fo-the-art wind system combines the accuracy of a research tool with the durability of an all-weather instrument. Other solid state wind measurement system exist; however, each of the them possesses technical characteristics that make them unsuitable for at sea operation. EII has concentrated development efforts on thermal resisistive film sensors as being within the realm of feasibility for the naval environment. Our company is confident that within six months after award the model 200m solid state system will meet U.S. Navy specifications.
