| 产品规格 | Used to determine the average effective pressure from the indicator diagram of the engine indicator easily and accurately. Also capable of, similarly to ordinary planimeters, measuring the area of intricate plane figures. Clip the figure to be measured on the plate to move the stylus along the closed figure. The difference between readings on the graduated ring before and after the stylus trip will provide the movement area of the figure in cm2. Range of the stylus: within 65 x 130 mm, One gradu |
| 中文汉化 | 652621 发动机示功器用面积仪 -----描述-----：该仪器用于从发动机示功图中简便且准确地测定平均有效压力，具有较高的测量精度。同时，它还可像普通面积仪一样，用于测量复杂平面图形的面积。使用时将待测图形固定在平板上，用探针沿封闭图形轮廓移动，移动前后指针在刻度环上的读数差即代表该图形所围面积，单位为平方厘米（cm2）。该仪器探针的测量范围为65 x 130 mm以内，刻度环每一格代表1 cm2，读数可精确到0.1 cm2，适用于工程计算和动力设备性能分析中的多种场合。 |
