Tantalum Electrode

Tantalum electrode is suitable for: concentrated hydrochloric acid, nitric acid, sulfuric acid, and other acid solutions, including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 175 ° C. In this paper, a tantalum electrode electromagnetic flowmeter to do to explain.

It is mainly used to measure the volume flow of conductive liquid and slurry in closed pipes. Strong corrosive liquids include acids, alkalis, salts, etc. . The part of the electromagnetic flowmeter in contact with the medium is not only the inner lining but also the electrode. It is important to choose the measuring electrode of the electromagnetic flowmeter correctly and reasonably to prolong the service life of the electromagnetic flowmeter.

Tantalum electrode electromagnetic flowmeter has full digital processing, strong anti-interference ability, reliable measurement, high accuracy, flow measurement range up to 150:1 ultra-low EMI switching power supply, suitable for a wide range of power supply voltage changes, and good anti-EMC performance.

Flowmeter features:

1. The Coil, an important part of the sensor, is designed optimally, and the measuring accuracy of the product is ensured by a strict real-flow test.

2. The signal electrode makes the thorough electrostatic shielding processing, guarantees the small signal not to be disturbed by the coil, and guarantees the low flow velocity the measurement accuracy.

3. The coil is isolated from the outside world to ensure the long-term insulation strength of the coil and the long-term measurement accuracy of the sensor.

4. All welding processes of the sensor are argon arc welding process, although the cost is higher, to ensure the reliability of welding (welding is the main production process of the sensor), especially after the installation of the coil welding process, the installed coil can not be damaged by argon arc welding process.

5. The structure of the grounding electrode is adapted to form a balance electrode plane, which ensures that the whole process of measuring average velocity is confined to the balance electrode plane, can eliminate the interference of electrical noise, and provide accurate measurements.

6. Use the custom-made double-shielded cable.

7. Programmable frequency low-frequency rectangular wave excitation, improves the stability of flow measurement, and low power loss.

8. High-frequency excitation is used in special medium measurements (such as grout) to eliminate clutter interference.

9. Using 16-bit embedded microprocessor, the operation speed is fast, and the precision is high.

10. All digital processing, strong anti-interference ability, reliable measurement, and high accuracy.

11. Ultra-low EMI switching power supply, suitable for a wide range of power supply voltage changes, anti-EMC performance is good.

12. Complete all functional designs with a single circuit board, using SMD device and SMT technology, the circuit reliability is higher.

13. High-definition backlit Chinese LCD display, showing the cumulative flow, instantaneous flow, flow rate, flow percentage, etc.

14. Menu operation, easy to use, easy to operate, easy to learn and understand.

15. The two-way measuring system has three accumulators which can display the positive accumulator, the reverse accumulator, and the difference accumulator.

16. With self-examination and self-diagnosis function, and on-screen display.

17. Lightning protection design.
