压力变送器的原理--是将一个空间用敏感元件(多用膜盒)分割成两个腔室,分别向两个腔室引入压力时,传感器在两方压力共同作用下产生位移(或位移的趋势),这个位移量和两个腔室压力差(差压)成正比,将这种位移转换成可以反映差压大小的标准信号输出。
3151/3051数显微差压液位变送器取压点的选取:
测量液体压力时,取压点应在设置工艺管道的下半部与工艺管道的水平中心线成0度~45度夹角的范围内;
量程的确定从扩散硅压力变送器的压力测量系数决定,一般选择量程时,我们通常使工作压力值大于标准量程值30%为宜,整个测量系统中可能出现的异常情况所导致的过载压力不得超过扩散硅压力变送器允许的过载量。测量动态管路液体压力时,还应考虑水垂效应,适当增大扩散硅压力变送器载量,如需相关技术帮助可咨询我公司技术部。
3151/3051数显微差压液位变送器怎样计算高度
1.显示百分比的计算方法
方法:如果表头看到显示了一个百分数,那么用百分数乘以量程则得出液位高度。百分比*量程=液位高度
举例:显示数值是30%,变送器量程是10米,那么液位就是3米了。
差压液位变送器怎样计算高度
常规时候还需要考虑毛细管的长度设计和稳定性考虑,
其典型的特征就是有1条或者两条长长的毛细取压管,我们也管这叫做单/双法兰差压变送器,有两条就是双法兰了。那么差压液位变送器毛细管长度有标准规定吗
通常在差压液位变送器选型表里面会给出这种关键参数指标的,常用的规格有3米,5米和10米三种,两跟毛细管长度都是一样长的。
最长最好不要超过10M,有的差压变送器厂家的毛细管是达不到10米的,所以具体要问,不过最好是最短越好的,价格就摆在那里。
在如航空航天、 军工、 石化、 化工、 油井、 电力、 船舶、 建材、 管道等众多行业。 一般用在液体、 气体或蒸汽的压力或绝对压力的测量,介质温度不太高,腐蚀性不强,粘稠度不高,不容易结晶等环境。3151/3051数显微差压液位变送器怎样选择取压位置
When measuring the liquid pressure, the pressure measuring point should be within the range of 0 ~ 45 degrees between the lower half of the set process pipeline and the horizontal center line of the process pipeline;
The determination of measuring range is determined by the pressure measurement coefficient of diffusion silicon pressure transmitter. Generally, when selecting the range, we usually make the working pressure value 30% higher than the standard range value. The overload pressure caused by the possible abnormal conditions in the whole measurement system should not exceed the overload allowed by the diffusion silicon pressure transmitter. When measuring the dynamic pipeline liquid pressure, we should also consider the water drop effect and appropriately increase the load of diffusion silicon pressure transmitter.

How to calculate the height of 3151 / 3051 digital display micro differential pressure level transmitter
1. Calculation method of display percentage
Method: if the indicator shows a percentage, then multiply the percentage by the range to get the liquid level height. Percentage * range = level height
For example: the display value is 30%, the transmitter range is 10 meters, then the liquid level is 3 meters.
How to calculate the height of differential pressure level transmitter
The length design and stability of the capillary tube should be considered in normal conditions,
Its typical feature is that there is one or two long capillary pressure pipes, which we call single / double flange differential pressure transmitter. There are two double flange. Is there a standard for the capillary length of differential pressure liquid level transmitter
This key parameter index is usually given in the selection table of differential pressure liquid level transmitter. The commonly used specifications are 3 m, 5 m and 10 m, both of which are the same length as the capillary.
The maximum length is not more than 10m. Some manufacturers of differential pressure transmitters have capillaries less than 10m, so we have to ask specifically, but the shortest is the best, and the price is there.
量測液體壓力時,取壓點應在設定工藝筦道的下半部與工藝筦道的水准中心線成0度~45度夾角的範圍內;
量程的確定從擴散矽壓力變送器的壓力測量係數决定,一般選擇量程時,我們通常使工作壓力值大於標準量程值30%為宜,整個量測系統中可能出現的异常情况所導致的超載壓力不得超過擴散矽壓力變送器允許的超載量。量測動態管路液體壓力時,還應考慮水垂效應,適當增大擴散矽壓力變送器載量,如需相關科技幫助可諮詢我公司技術部。

常規時候還需要考慮毛細管的長度設計和穩定性考慮,
其典型的特徵就是有1條或者兩條長長的毛細取壓管,我們也管這叫做單/雙法蘭差壓變送器,有兩條就是雙法蘭了。那麼差壓液位變送器毛細管長度有標準規定嗎
通常在差壓液位變送器選型錶裡面會給出這種關鍵參數名額的,常用的規格有3米,5米和10米三種,兩跟毛細管長度都是一樣長的。
最長最好不要超過10M,有的差壓變送器廠家的毛細管是達不到10米的,所以具體要問,不過最好是最短越好的,價格就擺在那裡。
