在农业工程中,特别是当前环境工程、农业工厂化生产以及畜牧业、禽类饲养、农产品贮藏加工等高速发展中,都必须对于环境的温度进行有效地检测和控制,那么怎样去实现有效地检测和有效地控制呢?近年来,热敏电阻在这些方面得到了广泛应用,并显示出它体积小、成本低、检测准确、反映速度快、使用方便、维修容易等几大特点。那么什么是热敏电阻呢?热敏电阻当然也是一种电阻。它是用热敏半导体材料加有机粘合剂高温烧结制成的。因此它有个特点:电阻值随着温度变化而改变,而且反映非常灵敏,同时还可根据需要制成各种不同的外形结构。热敏电阻就因为它具有这一大符点,随着技术科学的发展,它越来越广泛地被采用,如:温度测量、温度补偿、温
In agricultural engineering, especially in the current rapid development of environmental engineering, agricultural industrialization and livestock husbandry, poultry breeding, storage and processing of agricultural products, environmental temperature must be effectively detected and controlled, so how to achieve effective detection And effective control? In recent years, thermistors in these areas has been widely used, and showed its small size, low cost, accurate detection, reflecting the speed, ease of use, easy maintenance and several other major features. So what is a thermistor? Thermistor of course, is a kind of resistance. It is made of thermally-sensitive semiconductor material and organic binder sintered at high temperature. Therefore, it has a characteristic: the resistance changes with the temperature, but also reflects the very sensitive, but also can be made according to the needs of a variety of different shape and structure. Because it has this big point, the thermistor is being used more and more widely with the development of technological science, such as temperature measurement, temperature compensation, temperature
