一用途矢量机构力平衡变送器与原生产的杠杆式力平衡变送器的用途相同,分别用于测量液体、气体或蒸汽的差压、压力、流量,或测量开口和密封容器中的液位,或测量气体的负压。它可以把被测参数转换成0～10mA、D、C,电流输出,它们与DDZ—Ⅱ型仪表的其他单元可组合成自动测量、记录、调节、控制等系统。这种类型的变送器还有防爆型产品,经国家检定机关检定合格,可以适用于有爆炸性气体的危险环境中。二结构及工作原理本仪表的结构及工作原理如图1所示。 (以差压变送器为例) 作用于膜盒1上的差压转换为力,通过连接簧片2将此力作用于主杠杆4上,主杠杆以
One purpose vector force balance transducer with the original production of leveraged force balance transmitter uses the same, respectively, for measuring liquid, gas or steam pressure, pressure, flow, or measuring the opening and the liquid in the sealed container Bit, or measure the negative pressure of the gas. It can be measured parameters into 0 ~ 10mA, D, C, current output, they and other units of DDZ-II instrument can be combined into automatic measurement, recording, regulation, control and other systems. This type of transmitter also explosion-proof products, accredited by the national test authority qualified, can be applied to dangerous atmospheres with explosive gases. Second, the structure and working principle The structure of the instrument and working principle shown in Figure 1. (With differential pressure transmitter as an example) The differential pressure acting on the bellows 1 is converted into force, which acts on the main lever 4 by connecting the reed 2, the main lever
