电动差压变送器在工业检测测量中得到广泛的应用(如流量、液位),目前常见的DDZ—Ⅱ型、DDZ-Ⅲ型都是按力平衡原理来进行工作的,如图1所示。一髻二些三国厂’上一,一一一匕竺当T森伽图l测云杠杆系统的力平衡一、机械力变送器的几个主要调整装置 1.测量范围调整装置:它用来调整输入100%的差压
Electric differential pressure transmitter has been widely used in industrial testing and measurement (such as flow, liquid level), the current common DDZ-Ⅱ type, DDZ-Ⅲ are based on the principle of force balance to work, as shown in Figure 1 Show.
