传感技术中的硬件软化

利用微型计算机及其智能软件来仿效有关领域专家的设计思想,可使相应仪器仪表中的硬件结构减至最小限度,同时还提高了仪器仪表的功能:热电偶参考端智能补偿的精度优于0.02℃,所能补偿的环境温度范围为-200~+650℃,变压降节流式流量测量系统的在线自设计精度则优于0.2%。

Softenization of Hardware in the Transducer Technique

Mcrocomputer and an intelligent software embodied are used, so as to simulate expert's design ideas to minimize the hardware construction in related instrument and to improve its function, intelligent compensation accuracy of the reference junction of thermocouple can be better than 0.02℃, whereas the compensable temperature range of the circumstance is-200-650℃; the on-line design accuracyof flow measurement system with a variable pressure-drop type throtlling element is better than 0.2%.
