壓力式液位變送器_遠(yuǎn)傳式液位邊變送生產(chǎn)廠家/靜壓誤差的產(chǎn)生原因
1、對(duì)于差壓變送器來說，由于它的差壓刻度的檢驗(yàn)一般實(shí)在負(fù)壓室通大氣的狀態(tài)下完成的。但是，在現(xiàn)場(chǎng)操作過程中，常會(huì)存在這樣一個(gè)問題，對(duì)變送器進(jìn)行實(shí)際靜壓校零時(shí)可以發(fā)現(xiàn)，負(fù)壓室通大氣校驗(yàn)時(shí)的零位輸出與此刻的零位輸出值是存在差別的。
2、造成這一現(xiàn)象最主要的原因就在于，正負(fù)壓室膜盒的有效面積是不同的。當(dāng)它們處于同一壓力環(huán)境下時(shí)可以發(fā)現(xiàn)，由于它們的有效面積不同，所以膜盒上產(chǎn)生的合力是不等于零的。在這種情況下，就容易引起主杠位置發(fā)生偏移現(xiàn)象的出現(xiàn)，最終的結(jié)果就是造成零位漂移的情況。

As the main application direction in the manufacturing process of Xi'an Huaheng instrument, the remote liquid level transmitter is one of the application and use directions provided to customers by the manufacturer of Xi'an liquid level transmitter. In the production process of Xi'an instrument manufacturer, the long time is that the remote liquid level transmitter needs to use impulse pipe when using the measured medium, which is easy to solidify or crystallize, In the process of using the level transmitter, the pressure type level transmitter_ In the opinion of the manufacturer / instrument in Huaheng, if the temperature of the measured medium is too high or the corrosiveness cannot be measured directly, the remote liquid level transmitter will be used
At present, Xi'an liquid level transmitter 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.
Pressure type liquid level transmitter_ When the remote liquid level side transformer manufacturer / differential pressure liquid level transmitter is used, the static pressure influence (DP transmitter) can generally achieve the characteristics,
Zero error: for 14MPa, it is + 0.25% of Zui high range, and for range code 3, it is + 0.5% of Zui high range, which can be corrected by zero adjustment.
Range error: it can be corrected to + 0.25% of the input reading every 6Mpa, or + 0.5% for range code 3. This kind of error can be adjusted and eliminated before installation.
Pressure type liquid level transmitter_ Cause of static pressure error of remote liquid level side transformer manufacturer
1. For the differential pressure transmitter, because of its differential pressure calibration test is generally completed when the negative pressure chamber is open to the atmosphere. However, in the process of field operation, there is often such a problem. When the transmitter is calibrated by static pressure, it can be found that there is a difference between the zero position output when the negative pressure chamber passes the atmospheric calibration and the zero position output value at the moment.
2. The main reason for this phenomenon is that the effective area of the capsule is different. When they are in the same pressure environment, it can be found that the resultant force on the capsule is not equal to zero because of their different effective areas. In this case, it is easy to cause the offset of the main bar position, and the final result is to cause the zero position drift.
In the process of production, Xi'an Huaheng instrument manufacturer relies on its professional technical advantages, with the unique advantages of the process design of the metal capacitance sensor and the process manufacturing of the circuit board, which are rare in Northwest China, for example, the wind tunnel experiment of the county Jiaotong University, the industrial design of the two-way flow industry of the Northwest University of technology, etc., which can be applied in the design and manufacturing. In the production process of Xi'an liquid level transmitter, Based on the strong industrial plant in Northwest China, the process design with high stability and 0.1 precision based on the professional, economic and practical basis has a very important application in Gansu, Ningxia, Shaanxi, Qinghai, Xinjiang, many oil pipeline design, coal coking industry, natural gas production and exploitation
