采用热敏电阻作感温元件的温度指示控制仪已得到广泛应用.本文提出一种新型设计方案,即保持原来仪表的基本机械结构,采用统一规格、单只普通热敏电阻作感温元件及相应的电子线路.文中介绍了该方案的原理,并对其可行性及其误差进行了论证和分析.
The thermistor as a temperature sensing element temperature indication controller has been widely used.This paper presents a new design, that is, to maintain the original mechanical structure of the instrument, using a uniform size, a single common thermistor as a temperature sensing element and Corresponding electronic circuit.This paper introduces the principle of the scheme, and demonstrates its feasibility and error.
