多点动态温度巡回检测装置是为发电厂冷却水模型测量温度而进行设计的。在潮汐河道模型中进行冷却水试验,流体温度变化快,温差小,测温点多,测点布置密,所以对测温传感器的要求是:反应时间快、体积小、分辨率高、二次装置做到快速巡回检测。为了能测量模型试验瞬时温度场,首先要解决测温传感器的时间响应。只要测温传感器的响应时间短,再配上快速采集的二次装置,就能做到动态测温。根据试验要求,对几种常见的测温方法进行了分析研究,并进行厂试验。最后提出用露体热电偶作为测
Multi-point dynamic temperature circuit detection device is designed for measuring the temperature of the cooling water model of the power plant. In the tidal channel model for cooling water test, the fluid temperature changes quickly, the temperature difference is small, the temperature measurement points, measuring points arranged dense, so the temperature sensor requirements are: fast reaction time, small size, high resolution, secondary Device to do fast circuit detection. In order to measure the instantaneous temperature field of the model test, we must first solve the time response of the temperature sensor. As long as the temperature sensor response time is short, coupled with the rapid acquisition of the secondary device, you can do dynamic temperature measurement. According to the test requirements, several common methods of temperature measurement were studied and carried out. Finally, the use of dew thermocouple as a measure
