在科罗拉多州立大学，发动机和能量转换实验室(EECL) 是一个独特的跨学科研究/教育计划的实验室。EECL成立于1992年，迄今被公认为是一所在生物燃料研究项目、发动机、发动机控制、智能电网技术及能源 开发的全球领先的实验室。2011年，EECL创业进取卓有成效，被“大众科学”杂志命名为顶尖的研究实验室。他们以创业为方针，倡导以学生实践学习为中 心，在其研究的学科领域对全球具有影响效应。由于这个富于进取的能源技术研发，EECL及其附属公司已得到国际媒体的青睐（如《时代周刊》，《经济学 家》，《纽约时报》，《连线》，《大西洋月刊》，美国国家公共电台，TEDx杂志，微软全国广播公司, 美国广播公司, 哥伦比亚广播公司; 以及全球认可的《科学美国人》，劳力士企业精神奖，世界能源清洁奖; 史密森学会，皇家可持续发展奖，科技博物馆奖等。 ) 实验室通常有50-60位研究生和本科生。

The Engines and Energy Conversion Laboratory (EECL) is a unique interdisciplinary research/education program at Colorado State University. Established in 1992, the EECL is now recognized as a leading global research program in advanced biofuels, engines and engine controls, smart grid technology, and energy for development. In 2011, the EECL was again named one of the top University research labs in the nation by Popular Science magazine because of its entrepreneurial approach, global influence, and, as a pioneer of student-centeredexperiential learning. As a result of this enterprising approach to energy technology R&D, the EECL and its affiliates have received international press (Time, The Economist, The New York Times, Wired, The Atlantic, NPR, TEDx, MSNBC, NBC, CBS; as well as global recognition (Scientific American 10, Rolex Award for Enterprise, World CleanEnergy Award, The Smithsonian Institute, Royal Award for Sustainability, Tech Museum Award, etc.) The labtypically employs 50-60 graduate and undergraduate students.

EECL的研究任务是“创造创新的能源解决方案和创业模式，造福人类的条件和实现全球性的影响”。这也通过了：

? 基础和应用研究 – 开发新理念的发动机，能量转换，智能电网的电气化，生物燃料和智能建筑系统。

? 技术的发展和传播 – 通过与业界的伙伴关系，把EECL研究转变成现实世界的商业解决方案。

? 外联和协作 – 提供地方、国家和国际政府和环保机构支持，并在科罗拉多州柯林斯堡和国家支持清洁能源经济的发展。

? 教育培养 – 知识传播，人才培训，跨学科合作，发展和提高学生潜力和机会。

The Research Mission of the EECL is to “create innovative energy solutions and entrepreneurial models that benefit the human condition and achieve global impact.” This is addressed through:

? Basic and applied research – to develop new understanding of engines, energy conversion, smart grid electrification, biofuels and smart building systems.

? Technology development and dissemination – to turn EECL research into real-world commercial solutions through partnership with industry.

? Outreach and collaboration – to provide support to local, national and international government and environmental agencies, and to support the development of a clean energy economy in Fort Collins, Colorado and the nation.

? Education – dissemination of knowledge, training of people, interdisciplinary collaboration and the development and enhancement of student capabilities and opportunities.

最近EECL在一家当地的公司进行测试，他们制作了一个计算机模型，用于空气/能源存储设备。该测试需采集和记录超过40个不同的数据采集通道。其中一个 非常关键的测量要求是设备功率状况。该测量有两种实现方法：一个是用电表测量电压和电流，另一种是测量轴扭矩和转速。由于建立测试的空间有限，(< 5英寸的轴长度)、小轴直径(1¼英寸直径的轴), 能够测量正负的扭矩，并有好的分辨率和灵活的量程范围， 对扭矩测量装置要求比较高。该项目采用并安装了Binsfeld TorqueTrak10K扭矩遥测系统，应变片、发射机非常小巧，可以适应小的轴径，14位的分辨率，并对数据采集系统有很好的通用适应性，非常成功地 完成了这个测试项目。

Recently the Engines and Energy Conversion Laboratory (EECL) was approached by a local company to test, characterize, and generate a computer model for an air/energy storage device. This testing would require the construction of a new project specific test cell that would capture and record over 40 different data acquisition channels. One of the most critical measurements required is device power. This measurement was achieved in two ways; first by using an electrical power meter that measure electrical voltage and current and second by measuring shaft torque and speed. With the test cell setup having limited space (<5 inches of shaft length), a small shaft diameter (1 ¼ inch diameter shaft), the ability to measure both positive and negative torques, and have a fine resolution with scalability the requirements for the torque measurement device are very restrictive. A Binsfeld TorqueTrak 10K Torque Telemetry System was acquired and installed for usage on this project. With its minimal strain gauge/transmitter foot print, small shaft diameter capability, 14 bit resolution, and adaptability into the rest of the data acquisition system this device has fulfilled all the requirements for this project.
