Downscale burnout什么意思啊？ upscale 和 downscale burnout 的意思： the thermocouple burn-out function is mostly used in a temperature control system with a thermocouple input. if the thermocouple burns out, the controller loses the input signal. this is equivalent to the measured temperature becoming very low. then, the controller responds by trying to increase the heat typically, overheating the process, like a furnace. in order to prevent the overheating, a burn-out function is provided with the transmitter. the simple circuit of burn-out function generates a dummy signal of a high emf when the thermocouple or the extension wires' circuit opens. it drives the transmitter output higher than the 100% (or lower than 0%, if so chosen.) the controller will respond to the higher-than 100% signal to lower the controlled output. the temperature control system with the burn-out function prevents overheating of the process in a case of thermocouple burn-out. a thermocouple transmitters can have three options of the burn-out function: 1. the output signal becomes higher than 100%. (= upscale burn-out) 2. the output becomes lower than 0%. (= downscale burn-out) 3. no burn-out function查看更多
初次接触Aspen，遇到问题现请教各路大神？ 使用aspen运行后出现此问题，不知道是哪里出错了求大神指导，谢谢 - processing input specifications ... * warning in the "stream" paragraph which begins on line 40 stream name: 1 component mass fractions are normalized to unity. 查看更多
