1.前言差压变送器的诞生要追溯到30多年以前。此后,各种原理的变送器得到了开发。迄今,传感元件已有力平衡式、半导体式、电容式和振弦式等。美国的罗斯蒙特(Rosemount)公司成功地开发了电容式差压变送器。作为这种方式的开拓者,公司成为世界上公认的差压、压力变送器的供应厂家。它生产的差压变送器占美国市场的百分之六十。2051型高精度差压变送器是由1151型差压、压力变送器加以改进而成的,产品达到了高性能化。 2.特点 2051型通过采用浮动结构的传感元件和 1. Introduction Differential pressure transmitter birth dates back more than 30 years ago. Since then, a variety of principles of the transmitter has been developed. To date, sensing elements have been force balanced, semiconductor, capacitive and vibrating wire. Rosemount Inc. of the United States has successfully developed a capacitive differential pressure transmitter. As a pioneer in this way, the company became the world’s recognized supplier of differential pressure and pressure transmitters. It produces 60% of the differential pressure transmitter market in the United States. 2051-type high-precision differential pressure transmitter is 1151 type differential pressure, pressure transmitter to be improved from, the product reached a high performance. Features 2051 through the use of floating structure of the sensing element and
