      压力式液位变送器_远传式液位边变送生产厂家/  差压液位变送器在使用时，静压影响（DP变送器）普遍能做到的特点，
        零点误差：对于14MPa为zui高量程的+0.25%, 对于量程代号3为zui高量程的+0.5%，通过零点调整可以得到校正。
        量程误差：每6MPa可校正到输入读数的+0.25%，或对于量程代号3,为+0.5%。这种误差在安装前可以调校消除。
        压力式液位变送器_远传式液位边变送生产厂家/静压误差的产生原因
        1、对于差压变送器来说，由于它的差压刻度的检验一般实在负压室通大气的状态下完成的。但是，在现场操作过程中，常会存在这样一个问题，对变送器进行实际静压校零时可以发现，负压室通大气校验时的零位输出与此刻的零位输出值是存在差别的。
        2、造成这一现象最主要的原因就在于，正负压室膜盒的有效面积是不同的。当它们处于同一压力环境下时可以发现，由于它们的有效面积不同，所以膜盒上产生的合力是不等于零的。在这种情况下，就容易引起主杠位置发生偏移现象的出现，最终的结果就是造成零位漂移的情况。

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
