Tantalum ground ring in the instrument electromagnetic flowmeter has the following important applications:
1. Eliminate static interference: When the electromagnetic flowmeter works, the flow of fluid in the magnetic field will cause the measuring electrode to produce a potential signal, but the signal is generally weak, only a few millivolts, and is susceptible to static interference.The tantalum grounding ring directly contacts the medium through the grounding electrode, and then ground with the instrument flange, which can introduce the generated static electricity into the ground in time, thus eliminating static interference, ensuring the accuracy and stability of the measurement signal, and effectively improving the measurement accuracy of the electromagnetic flowmeter.
2. Reduce electromagnetic radiation error: The electromagnetic flowmeter may be affected by the surrounding electromagnetic field during operation, resulting in electromagnetic radiation error.The tantalum grounding ring has good electrical conductivity and can form a good grounding loop to guide the interference current generated by electromagnetic radiation to the earth, reduce the impact of electromagnetic radiation on the measurement results, and improve the stability of the electromagnetic flowmeter.
3. Prevent lightning damage: If the electromagnetic flowmeter is installed in an outdoor environment, it is vulnerable to lightning strikes.The tantalum ground ring can quickly introduce the current generated by lightning strikes to the ground, avoid the current to the electromagnetic flowmeter sensor, converter and other components caused damage, and play a role in lightning protection.
4. Adapt to harsh conditions: tantalum has very high corrosion resistance and high temperature resistance, in harsh working conditions, such as the measurement of highly corrosive media or high temperature media, tantalum ground ring can maintain good performance and stability.Compared with other ground rings, the tantalum ground ring has a longer service life, which can reduce the meter failure and maintenance costs caused by ground ring damage.
In short, the tantalum ground ring plays a vital role in the electromagnetic flowmeter, which can improve the measuring accuracy, stability and reliability of the instrument, and ensure the normal operation of the electromagnetic flowmeter, especially in some occasions with high measurement accuracy and stability requirements, such as chemical industry, metallurgy, electric power and other industries, the application of tantalum ground ring is of great significance.
