本文介绍一种压力、压差、流量和液位测量变送器,其工作原理是利用人造兰宝石单晶基片上异质外延硅膜的压阻效应。文中指出,在半导体应变测量装置中,使用单晶硅-兰宝石结构的基本优点。同时,文中给出兰宝石-22新系列测量变送器的基本性能指标。新产品的涌现、原有产品的发展与更新,是我们这个时代一个最显著的特征。核动力工程、化学工业和机械制造业已有了令人满意的发展。全新的工业体系和技术领域变成了现实。这些发展导致了对各种非电参数,例如压力、温度、液体和气体介质的流量、密闭容器中的液位、密度等进行测量的测量变送器需求量的增加。
This article describes a pressure, pressure, flow and level measurement transmitter, the working principle is the use of artificial sapphire single crystal substrate heterostructure silicon piezoresistive effect. It is stated in the article that the basic advantages of a monocrystalline silicon-sapphire structure are used in semiconductor strain gauges. At the same time, the article gives the blue gem -22 series of new measurement transmitter basic performance indicators. The emergence of new products, the development and updating of existing products is one of the most prominent features of our time. Nuclear power engineering, chemical industry and machinery manufacturing industry has been a satisfactory development. The new industrial system and technology became a reality. These developments have resulted in increased demand for measurement transmitters that measure various non-electrical parameters such as pressure, temperature, flow of liquids and gas media, liquid level, density in a closed container, and the like.
