电子测量尺 电子测量尺是应用航天技术生产出来的一种能够自动监测机动车辆的曲轴箱或变速箱中的液体高度的工具,它能够向驾驶员直接显示液面高度。这种电子测量尺是由CDI公司研制的,该公司专门向用户提供应用航天技术生产的工业产品。 图1的右侧是用于改造车辆和船只的仪表板,右侧是一个安装在轿车上的小型控制盒。图中的管状玻璃纤维是电子测量尺,前面为电子测量尺中的几个传感器。 这种电子测量尺采用微型负热敏电阻元件,该元件的电阻随着温度的变化而变化,这是液面测量工具所需的最基本的特性。 负热敏电阻元件在航天飞机发射中起了重要作用。轨道器上
Electronic measuring rulers Electronic measuring ruler is the application of aerospace technology to produce a can automatically monitor the motor vehicle crankcase or gear in the liquid height of the tool, which can be directly to the driver to display the liquid level. The electronic measuring ruler was developed by CDI Corporation, which specializes in providing industrial products to users using aerospace technology. The right side of Figure 1 is a dashboard for retrofitting vehicles and boats and the right is a small control box mounted on a car. Tubular glass fiber in the figure is an electronic measuring scale, in front of several electronic measuring scale sensor. This electronic measuring scale uses a miniature negative thermistor element whose resistance changes with temperature, which is the most essential characteristic of a level measuring tool. Negative thermistor elements play an important role in the launch of the space shuttle. Orbiter
