Three-Component Pitot Tube Sensor Development for Physical Oceanographic Investigations

9730433 Moum这个海洋仪器开发项目是为了建造和测试一种低成本、低功率的传感器，用于在小空间尺度上进行海洋速度的原位测量，这在微观结构和湍流研究中是至关重要的。拟议的方法是将目前用于飞机大气测量的三组分皮托管探针用于不同的海洋仪器套件。最近商业上可获得的低成本和低功率差压应变计表明，新设计的速度传感器可以取代某些现有的相对昂贵且功率要求高的海洋传感器。新的传感器应该能够在几厘米的尺度上以毫米-1的分辨率分辨速度。这些传感器将适用于放置、拖曳和系泊的仪器包，并将有助于计划和设想的观测平台的长期部署，以进行物理海洋调查。

9730433 Moum This oceanographic instrumentation development project is to build and test a low-cost and low power sensor for in situ ocean measurements of velocity on small space scales that are critical in microstructure and turbulence studies. The proposed approach is to adapt a three-component pitot tube probe, presently used for atmospheric measurements on aircraft, for use on different oceanographic instrumentation packages. The recent commercial availability of low-cost and low-power differential pressure strain gauges suggests that newly designed velocity sensors can replace certain existing oceanographic sensors that are relatively expensive and that have high power requirements. The new sensor should be capable of resolving velocities with mms-1 resolution on scales of a few centimeters. The sensors will be adapted for dropped, towed, and moored instrument packages and will be useful for planned and envisioned long-term deployments of observational platforms for physical oceanographic investigations.
