3151差压型液位变送器的工作原理(通用双语)

3151差压型液位变送器的工作原理.在立足西北,恩泽西北地区工业自动化进程,在在西安液位变送器厂家生产的过程中,时长会提到差压变送器的使用,差压液位变偶送器是在石油化工,市政控制中都有非常重要的使用.
The working principle of 3151 differential pressure liquid level transmitter. Based on the process of industrial automation in Northwest and northwest of Enze, in the production process of Xi'an liquid level transmitter manufacturer, the use of differential pressure transmitter will be mentioned for a long time. The differential pressure liquid level transformer coupling transmitter is very important in petrochemical industry and municipal control

3151差压型液位变送器的工作原理/3151液位变送器在西北地区,复杂工况应用中非常常见的一种液位变送器常见,在常见的液位变送器使用中都使用,在西安仪表制造厂家使用的过程中,由于差压型液位变送器能够利用金属电容式液位变送器的工作中,西安华恒仪表制造厂家的独立自主的金属电容式传感器,通过压力作用膜片作用到导压结算的金属表面产生的作用力.通过有效的膜片形变而产生微电压,形成差压信号,形成电压信号.
Working principle of 3151 differential pressure liquid level transmitter / 3151 liquid level transmitter is very common in the application of complex working conditions in Northwest China. It is used in common liquid level transmitters. In the process of using by Xi'an instrument manufacturer, because differential pressure liquid level transmitter can use metal capacitance liquid level transmitter, The independent metal capacitance sensor of Xi'an Huaheng instrument manufacturer acts on the metal surface of the conduction settlement through the pressure diaphragm. Through the effective deformation of the diaphragm, micro voltage is generated, differential pressure signal is formed, and voltage signal is formed
差压液位变送器指标测量原理
Measurement principle of differential pressure liquid level transmitter
水位变送器显示负值是水位测量上经常出现的问题之一,根据经验来看水位变送器显示负值可能有两种情况,一是变送器本身出现问题,即是产品质量或者安装过程出现问题,二是工艺设计本身需要变送器显示负值,最后一种情况是水位变送器经过负迁移。这两种情况都会导致变送器以负值的形式显示。
The negative value of water level transmitter is one of the common problems in water level measurement. According to experience, there may be two situations when the water level transmitter displays negative value. One is that the transmitter itself has problems, that is, the product quality or installation process has problems. The other is that the process design itself needs the transmitter to display negative value. The last situation is that the water level transmitter has undergone negative migration. Both conditions cause the transmitter to display as a negative value.
压式液位计测量原理图。当差压计一端接液相,另一端接气相时,根据流体静力学原理,有:
Measurement schematic diagram of pressure type liquid level gauge. When one end of the differential pressure gauge is connected with the liquid phase and the other end is connected with the gas phase, according to the principle of hydrostatics, there are:
PB=PA+Hρg (2-1)
PB=PA+Hρg (2-1)
式中: H——液体高度;
Where: H - liquid height;
ρ——被测介质密度;
ρ - density of measured medium;
g——被测当地的重力加速度。
G - the acceleration of gravity in the area to be measured.
由式(2-1)可得:
From equation (2-1), we can get:
ΔP= PB-PA= Hρg
ΔP= PB-PA= Hρg
一般来说,测量介质的密度和重力的加速度是已知的,因此由差压表测量的压差与液体H的高度成比例,使得测量的高度液体成为测量差压的问题。我们公司目前拥有三大技术实力,一是全隔离的智能电路处理单元技术,二是金属电容传感器的制造技术,三是全系列节流装置的多参量技术。
Generally speaking, the density of measuring medium and acceleration of gravity are known, so the pressure difference measured by differential pressure gauge is proportional to the height of liquid h, which makes the measured height liquid become the problem of measuring differential pressure. At present, our company has three technical strength, one is the fully isolated intelligent circuit processing unit technology, the other is the manufacturing technology of metal capacitance sensor, and the third is the multi parameter technology of the whole series of throttling devices.
