西安华恒变送器制造商已经开发出传感器和智能电路板这两项核心技术。 不仅掌握了所有产品的所有核心组件技术,而且工业自动变送器制造商的精度也在不断提高,从0.2提高到0.1。 通过扩展精通的核心技术,它还可以改变其他测量流量和温度的产品,华恒仪表-液位变送器厂家生产的3151智能型液位变送器在立足西北工业动化工业生产的过程中相对重要的仪器仪表.所测液体静压与该液体高度成正比的原理,采用扩散硅或陶瓷敏感元件的压阻效应,将静压转成电信号。

经过温度补偿和线性校正,转换成4-20mADC标准电流信号输出。


3151优质法兰式液位变送器安装过程中的特点/ 减少误差的方法如下:

The features of 3151 high quality flange type liquid level transmitter during installation / methods to reduce error are as follows:

1.导压管应尽可能短些;

1. The pressure pipe should be as short as possible;

2.当测量液体或蒸汽时,导压管应向上连接到流程工艺管道,其斜度应不小于1/12;

2. When measuring liquid or steam, the pressure pipe should be connected upward to the process pipeline, and its slope should not be less than 1 / 12;

3.对于气体测量时,导压管应向下连接到流程工艺管道,其斜度应不小于1/12;

3. For gas measurement, the pressure pipe should be connected downward to the process pipeline, and its slope should not be less than 1 / 12;

4.液体导压管道的布设要避免出现高点,气体导压管的布设要避免出现低点;

4. High points should be avoided in the layout of liquid pressure pipes, and low points should be avoided in the layout of gas pressure pipes;

5.两导压管应保持相同的温度;

5. The two pressure pipes should keep the same temperature;

6.为避免磨擦影响,导压管的口径应足够大;

6. In order to avoid the influence of friction, the diameter of pressure pipe should be large enough;

7.充满液体的导压管中应无气体存在;

7. There should be no gas in the pipe filled with liquid;

8.当使用隔离液时,两边导压管的液位要相同。

8. When using the isolating fluid, the liquid level of the pressure pipes on both sides should be the same.

9.清洁变送器压力接口和引压孔时,应使用三氯乙烯或酒精注入引压孔中,并轻轻晃动,再将液体倒出,如此反复多次。禁止使用任何器具伸入引压孔中,以避免损伤敏感芯体。

9. When cleaning the pressure interface and pressure hole of the transmitter, trichloroethylene or alcohol should be used to inject into the pressure hole, and shake it gently, and then pour out the liquid, and repeat for many times. It is forbidden to use any instrument to extend into the pressure hole to avoid damaging the sensitive core.

10.注意保护变送器引出电缆。在工业现场使用时,建议使用金属管保护或者架空。切勿松动电缆引出端的密封螺帽,避免潮气进入。

10. Pay attention to protect the outgoing cable of transmitter. It is recommended to use metal pipe for protection or overhead when using in industrial field. Do not loosen the sealing nut at the cable outlet to avoid moisture.
