CEC系列电容式变送器可以测量差压、压力、绝对压力、流量、液位、介质密度等参数,在结构上还有带远传法兰、带现场指示表等,广泛应用于冶金、石油、电力、化工、化肥等工业部门的生产过程。本文就以其中最典型的差压变送器为主,简要介绍工作原理、结构、研制过程中解决的几个主要问题和若干应用情况。关于变送器的规格、参数可参阅本期插页。
CEC series of capacitive transmitter can measure parameters such as differential pressure, pressure, absolute pressure, flow rate, liquid level and medium density. There are also far-field flanges in the structure, with on-site indication meter and so on, which are widely used in metallurgy, petroleum , Electricity, chemicals, fertilizers and other industrial sectors of the production process. In this paper, the most typical of the differential pressure transmitter based, briefly introduces the working principle, structure, the development process to solve several major problems and a number of applications. Transmitter specifications, parameters, see this insert.
